About Invoice Financing Cost Calculator
Invoice financing sounds cheap — '2% fee' — until you annualize it: 2% per 30 days on an invoice that takes 60 days to collect, advanced at 85%, is a 28.6% APR on the cash you actually received. This calculator does that conversion instantly, which is the only honest way to compare factoring quotes against a line of credit or a bank overdraft. Vocabulary decoded: the ADVANCE RATE (80–90% typical) is what you get upfront; the reserve arrives when your customer pays, minus fees. RECOURSE factoring (you eat the loss if the customer defaults) prices lower; NON-RECOURSE costs more and excludes disputes anyway. 'Invoice discounting' keeps collections with you confidentially; 'factoring' hands your customer relationship to the financier's collections desk — weigh that reputational texture. Used surgically, this is good debt: it scales with sales automatically, needs no hard collateral, and a one-off 25% APR for 45 days on a single large invoice costs less in dollars than losing the next order to a cash crunch. Used chronically across your whole ledger, it quietly converts your margin into the financier's revenue — if every invoice needs factoring, the business model, not the cash flow, is the problem.

Frequently asked questions
Why is the APR so much higher than the quoted fee?+
Three compounding reasons: the fee applies per 30 days (a 60-day invoice pays it twice); it's charged on the FULL invoice while you only received the advance (85%); and a year contains six 60-day periods. 2%/30 days at the defaults = 28.6% APR. Always annualize on the cash advanced — this tool does it automatically.
Recourse or non-recourse factoring?+
Recourse (you repurchase unpaid invoices) is 0.5–1.5%/month cheaper and right when your customers are solid corporates with slow AP departments. Non-recourse transfers insolvency risk only — not disputes or returns — and the premium often exceeds actuarial sense. Strong-customer ledgers should default to recourse and pocket the spread.
Will my customers know I'm factoring their invoices?+
Factoring: yes — payment redirects to the factor (notification), and their collections team follows up. Invoice discounting: no — you collect as usual and remit; it's confidential but reserved for businesses with solid books. If customer perception matters in your market, price the discounting premium as reputation insurance.
When does invoice finance beat a line of credit?+
When speed and scalability matter more than rate: lines need underwriting and cap out, factoring approves your CUSTOMERS' credit and grows with sales automatically. New businesses with blue-chip clients are the sweet spot. Established firms with bankable financials should usually get the LOC and keep factoring for overflow.
