Factoring calculator: what you get and what it costs, with the numbers in your offer.
Enter the invoice, the advance and the fee from your offer, how the fee is charged and how many days your customer takes to pay. You'll see the advance, the fee in dollars, what's released when your customer pays and the total you keep. It doesn't promise any rate: it does the math on yours.

The starting values are only an example: replace them with your offer. The calculator applies the fee to the full invoice, the same way 1st Commercial Credit's own calculator does. It isn't an offer or a quote.
How to read the result
- Advance today: what you receive when the invoice is verified.
- Factoring fee: the percentage that applies for the days your customer takes, in dollars.
- Released when your customer pays: the rest of the invoice, minus the fee and any other fees.
- Total you keep: the advance plus what's released. The difference with the invoice is your total cost.
The example button loads the numbers 1st Commercial Credit publishes on its invoice factoring page: a $500,000 invoice, a 90% advance and a 2% fee as sample figures. The result matches its page: $450,000 today, $40,000 when your customer pays and $490,000 in total.
What the calculator leaves out
- It applies the fee to the full invoice. If your offer charges it on the advance, or as interest on the money you use, the math changes: ask for an example in writing.
- If your offer has one fee for the first 30 days and another for the days after, add up the fee for your days and use the flat fee option.
- It doesn't know your rate. That depends on your volume, your customers' credit, how fast they pay and your industry, and it's confirmed in writing before you sign.
- If your customer never pays, what happens depends on whether your factoring is with or without recourse. See recourse vs non-recourse.
