As the school year winds down and we approach summer, charter schools across the country are deep into budgeting for the next fiscal year. One crucial component of charter school financial planning that deserves your attention right now is cash flow forecasting. In simple terms, cash flow forecasting means planning out how money will flow into and out of your school month by month, so you don't find yourself short on cash when bills are due. While budgeting for charter schools typically focuses on your revenue and expenses for the year, cash flow forecasting digs into the timing of those transactions.
Why focus on cash flow now? Because a budget alone isn't enough. You might have a solid annual budget on paper, but if the timing of revenues and expenses isn't aligned, your school could run into trouble paying teachers or keeping the lights on. In fact, many charter schools that have closed did so not because they lacked overall funding, but because they ran out of cash on hand at a point in time. Cash flow is the oxygen of charter schools—without steady access to it throughout the year, even a school with a balanced budget can financially suffocate.
This article will walk you through why cash flow forecasting matters (especially at this time of year), and, best practices for building a 12-month rolling cash flow forecast, and how to align your forecasts with key factors like enrollment trends, grant cycles, and compliance requirements. Our goal is to keep it professional yet conversational, breaking down advanced charter school finance best practices into accessible tips you can act on right away. Let's ensure your school stays financially healthy and ready to fulfill its mission in the coming year.
For charter school leaders, mid-May is a critical time. Most charter schools operate on a July 1 – June 30 fiscal year, which means right now you're likely finalizing budgets for the upcoming school year. It's tempting to think the hard work is done once you've balanced next year's budget. However, even a balanced budget can mask serious risks if you haven’t planned when cash actually comes in and goes out throughout the year. That's where cash flow forecasting comes in.
Cash flow forecasting is especially important now as you prepare for the next fiscal year because it acts as an early warning system. It lets you spot months where expenses might exceed incoming funds, so you can take action before a crisis hits. For example, many charter schools receive the bulk of their public funding in specific cycles or installments (e.g. state aid that might come monthly or quarterly, and grants that reimburse expenses only after documentation). Without a forecast, you might not realize that a large expense in August (like purchasing curriculum or funding summer teacher training in preparation for the start of the school year) will happen before your big per-pupil funding payment arrives in October. A cash flow forecast will highlight that gap, giving you time to adjust spending or arrange short-term financing to cover the difference.
Another reason forecasting matters now: the financial environment for schools is changing. During the COVID-19 pandemic, many schools benefited from one-time federal emergency funds; by fiscal 2025 those cushions are gone, meaning schools must return to pre-pandemic funding levels and stand on their own financial feet. At the same time, costs like salaries and facilities are rising with inflation, and enrollment trends are uncertain in some areas. In this context, having a clear picture of your cash flow is vital to avoid surprises. The majority of charter schools are financially stable with solid management and healthy liquidity, but for those with tight budgets, there is less flexibility now if something goes awry. A proactive cash flow plan can be the difference between calmly navigating a tough month or scrambling to pay the bills.
Finally, consider accountability and oversight. Charter school authorizers and boards are paying close attention to financial health. Schools that show signs of cash trouble – like low cash reserves or deficit spending – may get flagged for financial monitoring. Nobody wants their school landing on a “watch list” or being a recipient of a corrective action notice due to a preventable cash shortfalls. By forecasting cash flow, you demonstrate prudent financial management and can ensure you meet your compliance benchmarks (for ex: some authorizers or lenders require charter schools to maintain a minimum of 60 days of cash on hand). It’s all about being prepared. If you know a cash crunch is coming in March, you can plan for it in September – instead of being caught off guard. In short, now is the time to integrate cash flow forecasting into your planning process so that you enter the new school year confident and prepared.
How do you actually create a useful cash flow forecast? Here are some best practices to guide you when building or reviewing a 12-month rolling forecast for your charter school:
1. Start with your budget, then map it over time: Think of your cash flow forecast as your annual budget broken down by month (or even by week, if needed). List out all your expected cash inflows (e.g. state funding, federal grants, donations, etc.) and outflows (payroll, rent, utilities, supplies, etc.) for each month. Many schools use a simple spreadsheet with one column per month for 12 months. The goal is to see the net cash position at the end of each month (beginning cash plus inflows minus outflows). This exercise forces you to consider when each dollar comes in and goes out.
2. Make it a “rolling” forecast: A rolling 12-month forecast means you always maintain a forward-looking view for a full year ahead. For example, once July is over, you record the actual cash activity for July and then add July of the next year to the forecast. This way, you’re continuously planning a year out. By updating each month (dropping the month that passed and adding a future month), the forecast stays current and useful. Financial experts recommend updating cash flow projections monthly and extending them at least 12 months (even 18–24 months if your cash situation is tight). The payoff is early detection of issues; you won’t be caught by surprise by a cash shortfall in, say, next spring, because you'll see it coming this fall.
3. Be realistic and ideally, somewhat conservative: Base your forecast on sensible assumptions. If you know enrollment tends to come in a bit under projections, factor that in (ex: assume 90 - 95% of your target enrollment for funding, just in case). Likewise, don't assume that expenses will magically be lower than expected. It's better to slightly overestimate expenses and underestimate revenues. This creates a buffer in your forecast. If you end up with more cash than expected – great! You can then decide how to utilize the surplus (e.g., add to reserves or cover other needs). On the other hand, if something goes wrong, your conservative forecast has built-in wiggle room.
4. Incorporate seasonality and known patterns: Charter schools often have seasonal cash flow trends. For instance, expenses often spike in August/September as you purchase supplies and ramp up for the new year, and certain funding streams often hit later in the year. Plot these known timing events into your forecast. Identify your likely “low cash” point(s) during the year. If you know that, for example, right before the second state payment in winter your cash will be at its lowest, you can plan to hold back on discretionary spending until after that payment arrives. By mapping out the ebbs and flows, you won’t be caught off guard by predictable cash swings.
5. Use the right tool for your school (and know when to level up): While a well-structured Excel or Google Sheet can work for some smaller or less complex schools, many charter schools—especially those with multiple revenue streams, restricted funds, or growth plans—need more robust tools and expert guidance. Relying solely on a spreadsheet can lead to blind spots, errors, and missed early warning signs. Partnering with a firm like Charter Impact helps ensure your forecast is accurate, comprehensive, and strategic. At minimum, your tool should track operating revenues, operating expenses, and one-time sources and uses (like loans or capital purchases), with a clear line for ending cash each month. That ending cash number is your financial pulse—if it goes negative, treat it like a fire alarm and act fast to adjust inflows, cut expenses, or secure financing.
6. Review and adjust regularly: Set a routine (perhaps as part of your monthly financial review with your business manager or back-office provider) to look at the cash flow forecast. Compare what you projected for last month with what actually happened – are there big variances? If so, update future months accordingly. Maybe you expected 100 students but only 90 enrolled; then your revenue forecasts for the remaining months should be adjusted down. Or if a planned expense got delayed, move that cash outflow to a later month. Treat the forecast as a living document that evolves with new information.
7. Engage your team and board: Don't do forecasting in a silo. Involve key team members when building the assumptions – for example, talk to the enrollment coordinator about enrollment projections, or the development director about the likelihood of that big donation coming in. And share the forecast with your board finance committee or treasurer. In fact, many charter school boards expect to see a cash flow projection as part of regular monthly or quarterly financial reports. The best boards look at metrics like days cash on hand and rolling monthly cash flow forecasts to gauge financial health. Showing that you maintain a rolling forecast instills confidence that management is on top of cash management. It can also spur useful questions or advice from board members with finance expertise.
By following these practices, you'll transform cash flow forecasting from a tedious chore into a powerful tool. Instead of reacting to financial problems, you’ll be anticipating them and steering your school proactively. A bit of effort each month to update your forecast can prevent many headaches down the road.
Financial forecasting isn't just about plugging in numbers – it's about aligning those numbers with your school's strategy and obligations. Pay special attention to the following areas when developing your cash flow projections:
Enrollment drives the bulk of your revenue, so you need to align your financial forecasts with realistic enrollment expectations. Start by using historical data: What has been your student retention rate? Do you typically hit your enrollment targets, or do you see mid-year attrition? If your school is growing or adding new grades, factor in the ramp-up (e.g. new grade levels might not fill to capacity in year one). Conversely, be mindful of any local factors that could impact enrollment (such as a new charter school opening nearby or demographic shifts in your community). Monitor enrollment trends and use community insights to forecast enrollment and funding more accurately for example, if you know there's a healthy waitlist, you might be comfortable forecasting full enrollment, but if applications are soft, it’s prudent to project a lower number.
In practical terms, aligning with enrollment means if you project 5% fewer students, you also project the corresponding drop in per-pupil revenue and adjust expenses if possible. The goal is to avoid a scenario where you're expecting funding for students who don't materialize. It’s wise to build what-if scenarios: What if enrollment comes in 10% lower than expected? Your 12-month forecast can model that, letting you see how a shortfall would affect cash – and enabling you to plan how to cope (perhaps by delaying a hire or using a reserve fund). On the flip side, if enrollment surprises on the upside, your forecast will show additional cash coming in that you can allocate strategically (after ensuring any new expenses for those students are covered).
Also consider attendance if your state funds based on average daily attendance (ADA) rather than enrollment. If your ADA is typically, say, 95%, you might forecast revenue on 90% of enrolled students to be safe. Aligning to enrollment trends is about being honest with yourself; as one charter finance advisor put it, everything starts with your student count leading to your revenue, and then you have to adjust expenses accordingly. Keeping that principle in mind will ground your forecast in reality.
Charter schools juggle multiple funding streams – state aid, federal programs, grants, donations, etc. Each comes with its own timing and conditions. Align your cash flow forecast to these cycles so you anticipate when money will actually be in hand. For instance, if you receive state funding in equal monthly installments, your forecast can reflect that regular cadence. But many funds are not so uniform: perhaps your school receives 40% of its per-pupil funding in October and 60% in February (a pattern in some states), or federal Title funds arrive only after quarterly reimbursement requests are processed. Plot these specifics in your forecast.
Grant funding in particular requires strategic alignment. If you have a grant that runs on a different schedule or one that ends mid-year, mark those dates. Ensure your forecast shows the grant revenue stopping after its end date, so you can see the impact and plan accordingly. Also, plan the spending of grant money in your forecast: for example, if a technology grant of $100k must be fully spent by June, you might plan a cash outflow of $100k by that deadline (even if the cash was received upfront when the grant was awarded). This way your cash projection doesn’t falsely assume you still have that $100k available for other needs later on.
Be cautious about one-time and uncertain funds. If you've applied for a new grant but haven’t received confirmation, consider leaving it out of the main forecast (or create an alternate version that includes it). That way, you can see that you’re secure even without it – and any addition will be a bonus. Authorizers warn against over-reliance on tenuous funding sources; schools that depend too much on uncertain or one-off grants can find themselves in trouble if those funds vanish. A solid forecast will demonstrate how you plan to sustain operations as grants come and go. If a big federal relief fund (like ESSER) kept you afloat last year, show that you've adjusted expenditures or found new revenue to replace it this year.
Lastly, align with the mechanics of your funding streams: many grants are reimbursement-based. This means you spend first (cash out) and then get paid back (cash in). Always forecast the gap between spending and reimbursement. For example, if you know you'll spend $50k in October on a program and get reimbursed in January, your forecast for October should reflect the $50k cash outflow and only show the $50k inflow in January. This will make any temporary cash dips visible, allowing you to ensure you have enough liquidity or a line of credit to bridge the wait. In short, match your forecast to when funds actually move, not just the total amounts, to get a truthful picture of your cash position.
Every charter school operates under a set of financial compliance requirements - some formal, some informal. These could be conditions from your authorizer, state law, or even loan covenants if you have financing. Your cash flow forecast should be aligned to meet these benchmarks and requirements.
A common benchmark is having a minimum cash reserve or a certain number of days cash on hand. For instance, an authorizer or state rule might expect at least 30 days of cash on hand at all times. Use your forecast to check this: does your ending cash each month equal at least one month's worth of expenses? If not, that’s a sign you may need to build up more reserves or adjust spending. Financial oversight bodies often monitor things like low liquidity or continual deficit spending your forecast is the tool to ensure you’re not on a path toward those red flags. If you do see a projected deficit at year-end or a dip below required cash levels, you can course-correct now, rather than face consequences later.
Additionally, align your forecast with required reporting. Many charters must submit a budget and cash flow projection to their board or authorizer annually. Ensure the numbers you’re forecasting align with those official submissions (and if they change due to new information, be prepared to explain why). If you have debt (like a facilities loan or bond), check any covenants: you might need to maintain, say, a 1.1x debt service coverage ratio or a certain cash reserve for that lender. Your cash forecast can include debt service payment schedules and help confirm you'll have the cash on hand to meet those obligations and still satisfy the covenant.
Remember that compliance isn’t just about avoiding penalties – it’s about maintaining the trust of your stakeholders and your freedom to operate. A forecast aligned with compliance means you’re not just planning for cash; you’re planning to be financially sound by all required measures. This protects your school’s long-term health and ensures you can continue focusing on students rather than putting out financial fires. In short, use your cash flow forecast as a strategic tool to hit all the marks: keep your school solvent, accountable, and poised to seize opportunities (like a new grant or expansion) because you know exactly where you stand financially at any given time.
Cash flow forecasting might not be the most glamorous part of running a charter school, but it is certainly one of the most important. The good news is that with a bit of attention and the right approach, it becomes much less intimidating. By understanding why cash flow matters, avoiding common pitfalls, and implementing best practices like a rolling 12-month forecast, you've put your school on a path to financial stability. Aligning your forecast with enrollment realities, grant cycles, and compliance needs ensures there are no surprises waiting for you in the months ahead. This proactive approach means you can focus more on your school's educational mission and less on emergency financial firefighting.
