Accounting Funding Requirement Calculator
Estimate the funding your business may need to cover operating costs, payables and a cash reserve over a chosen period.
Overview
Use this Accounting Funding Requirement Calculator to estimate the cash your business may need over a chosen period. It compares current cash and expected customer receipts with operating costs, payables due and the cash reserve you want to keep.
How it works
The calculator multiplies monthly operating costs by the selected number of months. It then adds payables due and your desired cash reserve to find the total cash needed. Current cash and expected receivables are combined as available funds. If total cash needed is higher than available funds, the difference is the estimated funding requirement. If available funds are higher, the calculator shows a projected surplus instead.

Frequently asked questions
What is a funding requirement?
A funding requirement is the estimated additional cash a business needs to meet planned costs and payment obligations while maintaining a chosen cash reserve.
Should expected receivables be included?
Include receivables only when collection is reasonably likely within the selected period. Consider excluding overdue or uncertain invoices for a more cautious estimate.
Are payables included in monthly operating costs?
They may be, depending on how you prepare your figures. To avoid double counting, only enter payables separately when they are not already included in the monthly operating cost amount.
Why include a cash reserve?
A reserve allows for timing differences and unexpected costs. The suitable amount depends on how predictable your income, expenses and customer payment patterns are.
Does this calculator include loan interest or funding fees?
No. It estimates the cash gap before financing costs. Add expected interest, fees or repayment obligations to your expenses if they will arise during the period.
How often should I update a funding forecast?
Updating it monthly, weekly or more often can be useful when collections, supplier payments or operating costs change frequently.
