Estimates only, not a loan offer. Factor pricing is fixed at funding: the total cost does not fall if you repay early, unless your lender offers an early-repayment discount in writing. Weekly and bi-weekly debits also pull cash out faster than monthly billing — check the payment calendar against your cash cycle.
Enter the advance amount, choose APR pricing or factor-rate pricing, pick a monthly, bi-weekly or weekly payment — the calculator returns your payment per period, number of payments, total repayment, total cost of borrowing, cost per dollar borrowed and net proceeds after fees. No competitor tool combines all three switches in one place, and the combination is the point: short-term working capital is quoted in whichever frame makes it look cheapest, and the only honest comparison is the same advance priced both ways, at the frequency you will actually pay.
General information, not financial advice, and estimates only. Short-term quotes vary widely and contracts control; use this tool to translate a quote into comparable numbers before you sign.
APR mode: a $50,000 advance · 24% APR · 12 months · monthly payments:
Factor mode: the same $50,000 · factor rate 1.25 · 12 months:
Set side by side, the two modes stop being confusing: the factor loan costs $12,500 against the APR loan’s $6,735.76 on the same advance and term — and the factor number never moves, while the APR loan’s cost is interest on a declining balance. A factor quote only looks cheaper because “1.25” sounds smaller than “24%”; the tool exists to make that illusion impossible.
APR pricing is ordinary amortization at speed: each payment splits between interest on the current balance and principal, so the cost accrues over time. Pay early and you genuinely save the un-accrued interest. Factor pricing fixes the total on day one — advance × factor rate — and divides it into equal payments. No interest accrues because none exists; the cost is a flat purchase-price markup on the money. Two consequences follow. First, paying a factor-rate advance early does not reduce what you owe unless the contract grants an early-payoff discount — the $62,500 above is owed either way. Second, a factor rate has no APR until you specify a payment schedule: the same 1.25 paid weekly for a year and paid monthly for a year are different effective costs, which is why this page explains the equivalence (how interest is calculated) rather than stamping a single converted rate on it. If your quote instead carries a stated APR plus fees, converting it to a true APR is the APR calculator’s job.
Looking for the other “working capital calculator”? This page prices working capital loans. If you wanted the accounting figure, it is working capital = current assets − current liabilities — a balance-sheet calculation, not a loan, and not something this tool computes.
Weekly and daily debits are the short-term market’s quiet trap: the total cost barely moves with frequency, but the cash-flow timing does. A $1,201.92 weekly debit lands whether or not your customers paid you that week, and 52 chances a year to miss is a different risk profile from 12. Before signing a weekly structure, read the grace periods and first-payment timing page for how late windows actually work, and run the affordability calculator to check the debit against your cash flow’s coverage, not just its average. Firms that smooth this cycle by selling invoices rather than borrowing against them should also see the invoice financing hub — factor-style pricing appears there too, on a different asset. For a plain monthly term loan, the business loan calculator is the simpler tool.
How much does a working capital loan cost? On the worked example: $6,735.76 of interest for a $50,000 APR loan at 24% over 12 months, or $12,500 flat for the same advance at a 1.25 factor rate. The cost-per-dollar output states it without units games: $0.25 per $1 borrowed in the factor case. Your figure depends on amount, pricing mode and term — enter the quote as given.
How are working capital loan payments calculated? In APR mode, by amortization at your chosen frequency: the periodic rate is the APR divided by the payments per year (12, 26 or 52), and equal payments retire the balance over the term. In factor mode, by simple division: total repayment (advance × factor rate) split evenly across the number of payments. The calculator shows the payment count explicitly so the two methods cannot be confused.
What is the difference between a factor rate and APR? A factor rate is a multiplier on the advance that fixes your total repayment at funding — 1.25 on $50,000 means repaying $62,500, whenever and however you pay it. An APR is a yearly rate charged on the balance you still owe, so it rewards early repayment and punishes slow repayment. Factor rates are not rates at all in the APR sense; translating between them requires the actual payment schedule.
