Understanding Operating Reserves for Schools

What are operating reserves?

Operating reserves are the savings your school keeps on hand to cover unexpected expenses or revenue shortfalls. Think of them as your school's financial cushion - the safety net that keeps you operating when something doesn't go as planned. Reserves are typically expressed in "days of operating expenses" - how many days your school could continue operating using only its cash reserves, with no new revenue coming in.

Why reserves matter so much

Schools face all kinds of financial surprises:

• A grant you were counting on gets delayed by three months
• Enrollment comes in 15% below projections
• Your building needs an unexpected repair
• A key donor doesn't renew their annual gift
• Insurance premiums increase more than expected

Without reserves, any of these situations could force difficult decisions - cutting programs, delaying payroll, or worse. With adequate reserves, you can absorb the hit and keep your focus on educating students.

How much is enough?

There's no single "right" answer, but here are widely accepted benchmarks:

• 30 days - The absolute minimum. Enough to handle minor disruptions.
• 60 days - A reasonable target for schools in their first 2–3 years of operation.
• 90 days - The standard recommendation for established schools. This is what most financial advisors and authorizers consider healthy.
• 120+ days - Excellent. Provides significant flexibility for strategic investments or weathering major disruptions.

For context, 90 days of operating reserves for a school with $1 million in annual expenses means keeping about $247,000 in accessible cash.

How to calculate your reserves

The formula is straightforward: Days of reserves = (Cash + liquid investments) ÷ (Annual operating expenses ÷ 365) If you have $150,000 in cash and your annual operating expenses are $900,000: Days = $150,000 ÷ ($900,000 ÷ 365) = $150,000 ÷ $2,466 = 61 days

Building reserves into your financial model

The best time to plan for reserves is before your school opens - during the financial modeling phase. Here's how: Year 1: Don't expect to build significant reserves in your first year. You may even operate at a small deficit as enrollment ramps up. That's okay. Year 2–3: As enrollment grows and revenue stabilizes, your budget should show a net surplus each year. That surplus goes toward building reserves. Year 3–5: By Year 3, you should be targeting 60 days of reserves. By Year 5, aim for 90 days. In your model: Show a line item for "contribution to reserves" or "net surplus to cash reserves" that clearly demonstrates the path from startup to financial stability.

Where to keep your reserves

Reserves should be liquid - meaning easily accessible when you need them. Good options include:

• High-yield savings accounts
• Money market accounts
• Short-term Treasury bills or CDs (for the portion you won't need immediately)

Avoid tying reserves up in investments that are hard to access quickly or that could lose value.

Reserves and lender confidence

When lenders evaluate your school, reserves are one of the first things they look at. A school with 90 days of reserves demonstrates:

• Financial discipline and planning
• Ability to weather disruptions
• Lower risk of default on loan payments
• Mature financial management

Conversely, a school with no reserves (or a plan that never builds them) signals higher risk.

Common misconceptions

"We can't afford reserves - every dollar needs to go to students." Building reserves doesn't mean shortchanging students. It means protecting the school's ability to serve students over the long term. A school that runs out of cash can't serve anyone. "Reserves are just savings we're not using." Reserves aren't idle money. They're working capital that gives you the flexibility to make good decisions under pressure instead of desperate ones. "We'll build reserves later." If your financial model doesn't show a clear path to adequate reserves, lenders and authorizers will notice. Plan for it from the start.

Getting started

When you build your financial model in SchoolStack Budget, the platform tracks your projected cash position across all five years and calculates your days of reserves automatically. You can see exactly when you'll reach 30, 60, and 90 days - and adjust your plan if the timeline isn't where you want it. Building reserves isn't glamorous. But it's one of the most important things you can do to make sure your school is still serving students five, ten, and twenty years from now.
