Factoring Cost Calculator
Calculate the cost of invoice factoring and compare to waiting for payment.
Formula
Factoring Fee = Invoice Amount × Factor Rate × (Days Until Payment / 30) Advance Amount = Invoice Amount × Advance Rate (typically 80–90%) Total Cost = Factoring Fee + Additional Fees Net Proceeds = Advance Amount − Factoring Fee
How to Calculate
Invoice factoring lets you sell unpaid invoices to a factoring company for immediate cash. The factor advances you 80–90% of the invoice value upfront, then collects payment from your customer. When the customer pays, you receive the remaining balance minus the factoring fee.
The factoring fee is typically 1–5% of the invoice value per month (sometimes quoted as a flat rate per 30-day period). If the invoice takes longer to collect, additional fees may apply. The total cost depends on the factor rate, the advance percentage, and how quickly your customer pays.
To evaluate whether factoring makes financial sense, compare the cost to the benefit of having immediate cash. If receiving $45,000 today (instead of $50,000 in 60 days) allows you to take on a profitable new project, accept an early-payment discount from a supplier, or avoid a cash flow crisis, the factoring cost may be worthwhile.
Worked Example
A business factors a $50,000 invoice with these terms: Advance rate: 85% Factor rate: 3% per 30 days Customer pays in 45 days
Advance received: $50,000 × 85% = $42,500 Factoring fee: $50,000 × 3% × (45/30) = $2,250
When customer pays: Reserve returned: $50,000 − $42,500 = $7,500 Minus factoring fee: $7,500 − $2,250 = $5,250 returned
Total received: $42,500 + $5,250 = $47,750 Total cost of factoring: $50,000 − $47,750 = $2,250 Effective annual rate: (3% / 30) × 365 = 36.5% APR
Why It Matters
Invoice factoring is one of the fastest ways to convert receivables into working capital, but it comes at a significant cost. Understanding the true cost—including the effective annual rate—helps you compare factoring against alternatives like lines of credit, early-payment discounts, or simply waiting. Factoring should be a strategic tool, not a crutch for chronic cash flow problems.
Practical Tips
- ✓Compare the factoring cost to your cost of capital—a line of credit at 10% APR is much cheaper than factoring at 36%+ APR.
- ✓Factor only invoices from creditworthy customers to get better rates and terms.
- ✓Negotiate volume discounts if you plan to factor regularly.
- ✓Use factoring as a bridge, not a permanent solution—work on improving your collections process and payment terms in parallel.
