Accounting Funding Requirement (Monthly) Calculator

Estimate the external funding your business may need each month to cover expected cash outflows, maintain a cash reserve, and meet planned obligations.

Your Details

Overview

Use this Accounting Funding Requirement (Monthly) Calculator to estimate whether your opening cash and expected receipts can cover monthly expenses, supplier payments, debt commitments, and your desired closing cash reserve. It highlights the additional funding that may be needed for the month.

How it works

The calculator adds your opening cash, expected collections, and planned contributions to find the cash available for the month. It then subtracts all planned cash payments. If the resulting closing cash balance is below your target reserve, the difference is shown as the monthly funding requirement. If it is above the reserve, the excess is shown as cash above reserve.

How to use this calculator

  1. 1Enter the cash available at the start of the month.
  2. 2Add customer collections and any owner or investor funds expected during the month.
  3. 3Enter operating expenses, supplier payments, debt payments, and other planned cash outflows.
  4. 4Set the minimum closing cash reserve you want to keep.
  5. 5Review the estimated funding requirement and projected closing cash balance.

Frequently asked questions

What is a monthly funding requirement?

It is the extra cash a business may need during a month to pay planned obligations and maintain a chosen minimum cash balance.

Is the funding requirement the same as monthly profit?

No. This calculator focuses on cash timing. A profitable business can still need funding if customer payments arrive after bills are due.

Should I include unpaid invoices in expected collections?

Include only the amounts you realistically expect to receive during the month, rather than every invoice that has been issued.

What should be included in operating expenses?

Common items include payroll, rent, utilities, insurance, software, marketing, and other recurring costs paid in cash during the month.

Why set a target cash reserve?

A reserve can help cover routine timing differences and unexpected costs. The appropriate amount depends on your business's needs and risk tolerance.

What if the calculator shows no funding requirement?

Your projected cash is sufficient to cover the planned outflows and target reserve based on the figures entered. Actual results may differ if cash receipts or payments change.
