To calculate the total payback on a merchant cash advance (MCA), multiply the advance amount by the factor rate: for example, a $50,000 advance at a 1.35 factor rate equals $67,500 in total payback. The difference between the two figures — $17,500 in this case — is the cost of the financing. Unlike a loan, an MCA does not use an interest rate that accrues over time; the full repayment amount is fixed the moment you accept the offer, no matter how quickly or slowly you pay it off. This guide walks through the formula step by step, shows worked examples across common factor rates, and explains how to translate that fixed cost into an estimated APR so you can compare it fairly against other financing.
Key takeaways
- Total payback = advance amount x factor rate; the cost is the difference between the two.
- Factor rates typically range from about 1.10 to 1.50, meaning $0.10 to $0.50 in cost per dollar advanced.
- A $50,000 advance at a 1.35 factor rate equals $67,500 total payback and $17,500 in financing cost.
- Factor rates do not compound; the full repayment is fixed at signing regardless of how fast you pay.
- Daily payment = total payback divided by business days in the term (about 21 business days per month).
- The same fixed cost carries a higher effective APR over a shorter term — a 6-month payback can approach ~70% APR where a 12-month one is closer to ~35%.
- Advances commonly start at $10,000, with approval based on sales and deposits and funding in same day to 48 hours.
- Origination, ACH, or administrative fees can reduce the cash you receive while total payback stays the same.
- A reverse consolidation can lower the daily payment for businesses that already carry one or more advances.
The core formula: advance amount times factor rate
Every MCA payback calculation starts with two numbers your offer will state plainly: the advance amount (the cash you receive) and the factor rate (a decimal multiplier, usually between 1.10 and 1.50). The formula is simple:
- Total payback = Advance amount × Factor rate
- Cost of financing = Total payback − Advance amount
A factor rate is not a percentage and does not compound. A rate of 1.30 means you repay $1.30 for every $1.00 advanced. Because the total is fixed up front, paying the balance faster does not reduce what you owe unless your agreement includes a specific early-payoff discount. Always read the contract for that clause before assuming a fast payoff saves money.
| Factor rate | Cost per $1 advanced | On a $25,000 advance |
|---|---|---|
| 1.15 | $0.15 | $28,750 total ($3,750 cost) |
| 1.25 | $0.25 | $31,250 total ($6,250 cost) |
| 1.35 | $0.35 | $33,750 total ($8,750 cost) |
| 1.45 | $0.45 | $36,250 total ($9,000+ cost) |
Worked examples across advance sizes
Advances typically start at $10,000 and scale with your monthly revenue and card or deposit volume. Here is the total payback at a mid-range 1.35 factor rate across common advance sizes:
| Advance amount | Factor rate | Total payback | Cost of financing |
|---|---|---|---|
| $10,000 | 1.35 | $13,500 | $3,500 |
| $25,000 | 1.35 | $33,750 | $8,750 |
| $50,000 | 1.35 | $67,500 | $17,500 |
| $100,000 | 1.35 | $135,000 | $35,000 |
Notice that the cost scales in direct proportion to the advance. This makes the factor rate the single most important number to negotiate, because a shift from 1.35 to 1.25 on a $50,000 advance lowers total payback from $67,500 to $62,500 — a $5,000 difference for the same cash.
Turning total payback into a daily or weekly payment
MCAs are repaid through fixed daily or weekly remittances, or as a percentage of daily sales (a "holdback"). To estimate a fixed payment, divide the total payback by the number of business days or weeks in the estimated term.
- Daily payment = Total payback ÷ number of business days in term
- Weekly payment = Total payback ÷ number of weeks in term
Most terms run 3 to 18 months. Business-day counts assume roughly 21 business days per month (about 252 per year). Here is a $50,000 advance at 1.35 ($67,500 total) across three term lengths:
| Estimated term | Business days | Estimated daily payment | Estimated weekly payment |
|---|---|---|---|
| 6 months | ~126 | ~$536 | ~$2,596 |
| 9 months | ~189 | ~$357 | ~$1,731 |
| 12 months | ~252 | ~$268 | ~$1,298 |
With a percentage-of-sales holdback rather than a fixed debit, the exact daily amount rises and falls with your deposits, so the term shortens in strong months and stretches in slow ones — but the total payback stays the same.
Converting the factor rate to an estimated APR
Because a factor rate ignores time, two advances with the same total payback can carry very different true costs depending on how fast you repay. Converting to an annual percentage rate (APR) lets you compare an MCA against term loans, lines of credit, or cards on equal footing. A widely used approximation is:
- Estimated APR ≈ (Cost of financing ÷ Advance amount) ÷ (Term in days ÷ 365) × 100
Using the $50,000 advance at 1.35 ($17,500 cost) shows why term length matters so much:
| Term | Cost ratio | Approx. APR |
|---|---|---|
| 6 months (~182 days) | 35% | ~70% |
| 9 months (~273 days) | 35% | ~47% |
| 12 months (~365 days) | 35% | ~35% |
The same $17,500 cost becomes a far higher effective APR when repaid quickly. This is the key insight the factor rate hides: shorter terms and daily remittances push the true cost well above what the headline number suggests.
Fees, stacking, and other adjustments to check
The factor-rate formula gives you the base payback, but your net cost can shift for a few reasons. Review the agreement for each of these before you sign:
- Origination or underwriting fees — sometimes deducted from the amount you receive, so you get less than the stated advance while still repaying the full total.
- ACH or administrative fees — small per-debit charges that add up across dozens of payments.
- Early-payoff terms — most MCAs offer no interest savings for paying early, but some include a defined discount; confirm it in writing.
- Existing advances — if you already carry an MCA, taking a second or third position increases your combined daily obligation. A reverse consolidation can lower the daily payment by restructuring what you remit, rather than eliminating a balance.
When comparing offers, always work from total payback and estimated APR — not the factor rate alone — and factor in any deductions from the disbursed amount so you are comparing the real cash in hand against the real cost.
Frequently asked questions
What is the formula for MCA total payback?
Total payback equals the advance amount multiplied by the factor rate. For example, $40,000 at a 1.30 factor rate equals $52,000 in total payback, of which $12,000 is the cost of financing.
Is a factor rate the same as an interest rate?
No. A factor rate is a fixed decimal multiplier that sets your total repayment up front and does not accrue over time. An interest rate compounds on a declining balance. That difference is why MCAs generally need to be converted to an estimated APR for a fair comparison.
Does paying off an MCA early save money?
Usually not. Because the total payback is fixed at signing, paying faster does not reduce what you owe unless your specific agreement includes an early-payoff discount. Always confirm whether that clause exists before assuming a fast payoff lowers the cost.
How do I estimate my daily payment?
Divide the total payback by the number of business days in the estimated term (roughly 21 per month). A $67,500 total payback over a 9-month term of about 189 business days works out to roughly $357 per day.
Why can the APR be so much higher than the factor rate implies?
Because the factor rate ignores time. The same fixed cost repaid over 6 months carries a far higher effective APR than the same cost repaid over 12 months. Shorter terms and daily remittances push the true annualized cost well above the headline figure.
What advance amounts and terms are typical?
Advances commonly start around $10,000 and scale with monthly revenue and deposit volume. Terms usually run 3 to 18 months, with approval based on sales and deposits rather than credit score alone, and funding often available same day to 48 hours.
Can I lower my daily payment if I already have an advance?
Yes, through a reverse consolidation, which restructures what you remit each day to lower the daily payment. It reduces daily cash-flow pressure rather than eliminating a balance, so review the total cost of the new arrangement carefully.
