Invoice Factoring Calculator

Invoice factoring gives a business faster access to cash tied up in unpaid invoices. Instead of waiting for the client to pay, you may receive an advance from a finance provider. The provider then charges a fee and releases any remaining reserve based on the agreement.

This calculator uses a simple estimate model. You enter the invoice amount, the advance percentage, the fee percentage, the expected number of days until the client pays, and any extra fees. It then shows upfront cash, reserve before fees, estimated cost, net received, and effective annualized cost.

The effective annualized cost helps compare invoice factoring with other funding options. A small fee can become expensive when annualized over a short period, so reviewing both dollar cost and percentage cost is important.

Invoice financing may help when a strong client pays slowly but your business needs payroll, inventory, or project delivery cash sooner. It can also be useful when growth creates a timing gap between issuing invoices and receiving payment.

The tradeoff is cost. If the invoice is likely to be paid soon, the fee may not be worth it. If the payment delay blocks important work, the cost may be acceptable. This is why a calculator is useful before speaking to a provider.

Do not treat calculator output as a financing offer. Actual rates, reserve releases, recourse terms, and collection rules depend on the provider and contract.
