Frequently Asked Questions
Common questions about invoice factoring costs and decisions.
How much does invoice factoring cost?+
Invoice factoring typically costs 1-5% of the invoice face value per 30-day period. The exact rate depends on your industry, invoice volume, customer creditworthiness, and payment terms. A 3% fee on a Net 60 invoice translates to roughly 18% annualized. Most factors also hold back 10-20% of the invoice as a reserve, which is released after the customer pays. For businesses with tight cash flow, understanding the true cost helps you compare factoring against alternatives like a better accounts receivable process or negotiating shorter payment terms.
When is invoice factoring worth it?+
Invoice factoring is worth it when the opportunity cost of waiting for payment exceeds the factoring fee. Common scenarios include: you have a high-ROI growth opportunity that requires immediate cash, your operating expenses exceed current cash on hand, or slow-paying customers are forcing you to miss supplier discounts. If you are simply bridging a temporary gap, factoring can prevent costly alternatives like high-interest debt. Use our burn rate calculator to see how delayed payments affect your runway.
What is a typical advance rate for factoring?+
Most invoice factors advance 70-90% of the invoice face value upfront, with 80% being the most common rate. The remaining 10-30% is held as a reserve until the customer pays. The advance rate depends on your industry, the creditworthiness of your customers, and the age of the invoices. Government invoices and large enterprise invoices often qualify for higher advance rates because the payment risk is lower. After the customer pays, you receive the reserve minus the factoring fee. Managing your cash flow forecast helps you decide how much to factor versus wait.
When Invoice Factoring Makes Sense for Your Business
Invoice factoring converts your unpaid invoices into immediate cash, but the real question is whether the cost justifies the speed. This calculator helps you answer that by comparing the factoring fee against the opportunity cost of waiting 30, 60, or 90 days for your customers to pay.
The most overlooked part of the factoring decision is the effective annual rate. A 3% fee sounds small, but on a Net 30 invoice that works out to roughly 36% annualized. On Net 90, the same 3% is closer to 12% annualized. Understanding this distinction is critical for businesses that rely on factoring regularly rather than as a one-time bridge. For a broader look at managing receivables, our guide on accounts receivable best practices covers strategies that reduce your dependence on factoring over time.
The opportunity cost calculation assumes a 10% annual return on deployed capital, which is conservative for most growing businesses. If your business can generate higher returns with immediate cash — through inventory purchases, marketing spend, or hiring — the threshold for factoring being worthwhile drops significantly. Track your actual cash deployment returns using a cash flow forecast to make this comparison more precise.
Businesses with high DSO (days sales outstanding) relative to their payment obligations benefit most from factoring. If your customers pay in 60-90 days but your suppliers require payment in 30, that gap creates a permanent working capital shortfall. Factoring closes that gap, but it should be part of a broader strategy. Review your invoice payment terms to see if adjusting terms or offering early payment discounts could reduce your factoring needs.
