Business revenue and available cash are not the same thing. Your company may have strong sales and still struggle to cover payroll, rent, or an urgent repair. A dedicated cash reserve can help your business continue meeting essential obligations when money comes in later than expected or an unplanned expense arises.
How Much Should You Keep in Reserve?
A common starting point is enough cash to cover three to six months of essential operating expenses. That range is a guideline, not a universal rule. The right amount depends on your business model, revenue patterns, payment cycles, staffing, and fixed costs.
A business with reliable monthly revenue and quick customer payments may need a different reserve than a seasonal company that regularly waits 60 or 90 days for invoices to be paid. Your goal should reflect how money moves through your business, not an arbitrary number.
Which Expenses Should Your Reserve Cover?
Start by identifying the costs your business must pay to keep operating. These may include:
- Employee payroll and benefits
- Rent or mortgage payments
- Utilities, insurance, and required licenses
- Essential inventory, supplies, and vendor payments
- Required loan or business credit card payments
- Software, technology, and professional services
- Equipment maintenance and repair
- The business owner’s regular compensation
Separate essential expenses from costs you could pause or reduce. That distinction gives you a more realistic estimate of the minimum your business needs each month.
How to Calculate a Starting Goal
- Review a Full Year of Expenses
Look at the previous 12 months to capture costs that do not occur every month, such as annual insurance premiums, licensing fees, tax payments, or seasonal inventory purchases.
- Calculate Average Essential Monthly Costs
Add your essential operating expenses for the year and divide the total by 12. For example, if essential expenses total $240,000, your average monthly operating cost is $20,000.
- Select a Coverage Target
Multiply that monthly amount by the number of months you want the reserve to cover. Using the example above, a three month reserve would be $60,000 and a six month reserve would be $120,000.
Factors That May Change Your Target
Revenue Consistency: Seasonal sales, project-based work or large month-to-month changes can create longer gaps between income and expenses. Reviewing prior cash flow patterns can help you prepare for slower periods.
Customer Payment Timing: If customers routinely pay on longer terms, your reserve may need to cover several weeks of operating costs while invoices remain outstanding. Track how long it actually takes to collect payments, not just the terms shown on your invoices.
Payroll and Fixed Overhead: Businesses with employees, leased space, or other significant fixed costs may use cash more quickly than businesses with flexible overhead. You’ll also want to include any owner compensation so the estimate reflects the true cost of operating the company.
Essential Equipment and Concentrated Revenue: Consider what it would cost to repair equipment your business cannot operate without. You may also need a larger cushion if one customer provides a significant portion of your revenue.
Practical Ways to Build Your Reserve
- Create a specific reserve goal and include contributions in your monthly budget.
- Transfer a set dollar amount or percentage of revenue on a consistent schedule.
- Send invoices promptly and follow up on overdue balances.
- Review recurring expenses and redirect unnecessary costs into savings.
- Keep reserve funds separate from the account used for everyday purchases.
- Set guidelines for when the reserve can be used and how it will be replenished.
Review as Your Business Changes
Revisit your reserve goal when you hire employees, add equipment, or experience changes in customer payment timing. A reserve that worked two years ago, may not reflect today’s operating costs.
A separate deposit account can make your reserve easier to track while keeping the funds accessible. If your business is local to Monmouth or Ocean Counties, learn more about First Financial Business Savings Accounts, call 732-312-1500 to speak with a member of our team, or visit a local branch.
