Factor Rate Calculator — What Your Business Funding Actually Costs

Last updated: September 15, 2026

Most business owners sign a factor-rate agreement without ever seeing the real math. The number is small — 1.2, 1.25, 1.3 — and it hides the actual cost better than any interest rate ever could.

Quick Answer

A factor rate is a fixed multiplier applied to your funding amount, not an interest rate. A $50,000 advance at a 1.25 factor rate costs $62,500 total — $12,500 in financing cost — no matter how long repayment takes. Use the calculator below to see your total payback, cost of capital, and estimated payments before you sign anything.

The Factor Rate Calculator

Enter the numbers from any funding offer. The calculator shows the total you will repay, the cost of the capital, and what each payment looks like at your revenue. Nothing is stored, and the results are estimates — not offers.





The Math Behind the Numbers

Every result above comes from three formulas. Knowing them is the difference between comparing offers and just taking the first one presented.

Total payback = funding amount × factor rate. This is fixed on day one. If you receive $50,000 at 1.25, you owe $62,500 — whether repayment takes five months or nine.

Cost of capital = funding amount × (factor rate − 1). That same deal costs $12,500. That is the real price of the money, and it is the number to compare across offers — not the factor rate alone, because a bigger advance at a lower rate can still cost more dollars.

Estimated monthly payment = average monthly revenue × repayment percentage. If your business averages $40,000 a month and commits 10%, you pay about $4,000 a month — more in strong months, less in slow ones, because revenue-based repayment follows deposits.

Estimated months = total payback ÷ monthly payment. This is why the repayment percentage matters so much. A low percentage feels comfortable but stretches the timeline. A high percentage clears the debt faster but squeezes cash flow. Most healthy balances land between 8% and 15%.

Factor Rate vs. Interest Rate — Why the Difference Matters

An interest rate applies to a shrinking balance. As you pay a bank loan down, interest accrues on less money each month. A factor rate applies once, to the full amount, on day one. The two are not interchangeable, and any provider who blurs that line is counting on you not to notice.

Feature Bank loan (interest rate) Revenue-based financing (factor rate)
Applied to Declining balance Full amount, once
Total cost Varies with payoff speed Fixed on day one
Payments Fixed amount, fixed dates Percentage of deposits — rises and falls with revenue
Slow month Late fee, credit damage Smaller payment, no penalty
Typical time to fund Weeks to months Days after approval, though timelines vary by provider

A Worked Example, Start to Finish

Here is the illustrative example used in the calculator’s default settings. Illustrative example — not a real client.

A restaurant owner takes $50,000 at a 1.25 factor rate with 10% of deposits committed. Total payback: $62,500. Cost of capital: $12,500. The restaurant averages $40,000 a month, so roughly $4,000 a month flows to repayment.

August is strong — $52,000 comes in, and $5,200 goes to the advance. September softens to $31,000, and the payment eases to $3,100. No late call, no penalty. At that blended pace the advance clears in about 6 to 7 months, and the owner paid $12,500 for capital the bank would not give him at any price on that timeline.

Now the comparison that matters. The same owner offered 1.35 elsewhere would pay $17,500 for the same $50,000 — $5,000 more for the identical product. Two offers, one question: what does the money actually cost in dollars? That is what this calculator exists to answer.

How Providers Set Your Factor Rate

Factor rates are not pulled from the air. Providers price them off four signals, and knowing the signals tells you where your offer can improve.

Monthly revenue and its consistency. This is the core of revenue-based underwriting. A business averaging $40,000 a month with steady deposits looks different from one that swings between $8,000 and $70,000, even at the same average. Consistency earns better pricing.

Time in business. Six months of documented deposits is a floor for most providers. A track record of two or more years supports both larger amounts and tighter rates.

Overall file strength. Credit history, industry, existing advances, and bank-statement health all shift the rate up or down. This is why two identical-sounding businesses can be quoted 1.2 and 1.4 for the same amount.

Amount and term. Larger advances and shorter expected terms can carry different pricing. There is no single market rate — which is exactly why you should always compare at least two offers with the same inputs in this calculator before deciding anything.

Reading the Offer: Five Questions Before You Sign

Run every offer through this checklist. A provider that answers all five cleanly is one you can negotiate with.

1. What is the total payback in dollars? Not the rate — the dollars. A 1.25 on $60,000 costs more than a 1.3 on $40,000. The calculator above answers this instantly.

2. What percentage of deposits does repayment take, and for how long? If the percentage plus your normal operating costs exceeds your gross margin, the deal squeezes you no matter how good the rate looks.

3. Does the total change if repayment runs long? With a true factor-rate agreement it should not. If the paperwork adds fees or interest when repayment stretches, you are not looking at a fixed-cost product.

4. What happens in a genuinely bad month? Revenue-based repayment should shrink with deposits. Get the answer in writing before you need it.

5. Is there an early-payoff discount? Some agreements reduce the total if you clear it early. Ask — the worst answer is no, and no is still worth knowing before signing.

What the Federal Data Shows About This Market

Revenue-based financing grew because banks stepped back. Year after year, Federal Reserve surveys of small business credit have found that a meaningful share of applicants are denied or approved for less than they sought, with the gap falling hardest on the smallest firms — precisely the businesses revenue-based underwriting is built to serve. Federal regulators have responded by pulling more daylight into small business lending: the Consumer Financial Protection Bureau maintains a dedicated small business lending rules and policy page covering how business credit data is collected, reported, and disclosed.

Several states now require commercial-financing disclosures — including the annualized cost of non-loan products like factor-rate agreements — before a business signs. California’s commercial financing disclosure law was the first and remains the model. If your provider volunteers an annualized-percentage disclosure before you ask, that is a good sign.

Using the Calculator to Compare Two Offers

Comparison shopping for factor-rate funding works best with a fixed routine. Gather both offers side by side, and for each one note the funding amount, the factor rate, the committed repayment percentage, and any fees listed in the fine print.

Run offer A through the calculator and write down three numbers: total payback, cost of capital, and estimated repayment time. Clear the inputs — or open the calculator in a second window — and run offer B the same way.

Then compare on three axes. First, dollars: which offer costs less in total? Second, pace: which repayment percentage fits your real monthly margin without pinching payroll, rent, or inventory? Third, trust: which provider answered the five questions above without dodging?

The cheapest offer on paper is not automatically the right one. A slightly higher factor rate from a provider whose terms are transparent and whose repayment flexes with your revenue can be worth more than a headline number from one that hides fees in the schedule. But you cannot see any of that until both offers are converted into the same three numbers — which is the one job this tool does.

Who This Calculator Is For — And Who It Is Not

It is for: any owner holding a factor-rate offer who wants the real cost in dollars and plain English before signing; owners comparing two or more offers; owners checking whether a quoted repayment percentage leaves enough margin to operate.

It is not for: new ventures without established monthly revenue, where a revenue-based advance rarely makes sense; owners with revenue below roughly $10,000 a month, where the repayment percentage would squeeze cash flow too hard; or anyone treating an estimate as an approval. The outputs are arithmetic, not underwriting. Actual terms always depend on the provider, your documented revenue, and the agreement you sign.

If the calculator shows a deal that fits, the next step is seeing what your revenue actually qualifies for. The requirements are simpler than most owners expect.

Frequently Asked Questions

Is a factor rate the same as an interest rate?

No. A factor rate is a fixed multiplier applied once to the full funding amount, while an interest rate applies to a declining balance over time. A 1.25 factor rate on $50,000 means a fixed $62,500 payback regardless of how quickly you repay.

Is a 1.35 factor rate expensive?

It depends on the funding amount, the repayment pace, and what the capital earns. On $50,000, a 1.35 factor rate costs $17,500. Whether that is worth it depends on what the money does for the business — buying discounted inventory that resells at a strong margin is a different decision than covering a slow month.

Does paying off a factor-rate agreement early save money?

Usually not in the way it does with a bank loan. Because the total is fixed on day one, paying early typically means paying the same amount sooner. Some agreements offer early-payoff discounts — read the specific terms before assuming.

What happens to my payment in a slow month?

With revenue-based financing, the payment shrinks with your deposits. If revenue falls 30%, your payment falls roughly 30% too. There is no fixed minimum the way a bank loan has, though the repayment simply takes longer.

How is the estimated repayment time calculated?

Total payback divided by the monthly payment (average monthly revenue multiplied by the committed repayment percentage). It is an estimate — real repayment follows your actual deposits, which rise and fall.

Does using this calculator affect my credit or obligate me to anything?

No. The calculator runs entirely in your browser using the numbers you enter. Nothing is submitted, stored, or shared, and nothing touches your credit.
