The financing offer

Also called the factor rate: 12% means you repay 1.12× the advance.

Processing fee, GST on it and anything else held back from the cash paid out.

Revenue and repayment

Lenders usually sweep gross gateway collections, GST included, which repays them faster. Enter revenue above without GST.

Advanced options

A weekly gateway sweep repays sooner than a month-end sweep, so the same fee costs more a year.

Illustrative 15% — replace with yours. Shows how much of your monthly margin the sweep takes.

Your result

55.47%

You receive ₹49,00,000 and repay ₹56,00,000 over 5 months. Counting how fast it is repaid, that is 71.99% a year compounded.

Warning:

The sweep takes 93.33% of your monthly contribution margin

The monthly sweep of ₹11,20,000 is 93.33% of your monthly contribution margin (CM3) of ₹12,00,000. Little is left for fixed costs, so a slow month could leave a gap.

What this tells you

Revenue-based financing is quoted as a flat fee on the advance, repaid from a share of each month’s sales. The real cost depends on the cash you actually receive and how quickly the sales repay it.

Enter the offer and your sales to see the true annual cost as APR and EAR, how a strong sales month changes it, and what a bank loan of the same cash would cost.

Assumptions used

  • Product GST rate choices: 0%, 5%, 12%, 18%, 40%, or a custom rate.
  • Monthly revenue stays the same each month; the spike scenario applies the change to every month.
  • The revenue share is swept monthly (or weekly, if chosen), and the last payment is only what is left of the cap.
  • Weekly sweep: the monthly sweep ÷ 52/12 is collected every week.
  • GST in the sweep base: the GST rate you choose is added to the revenue you enter, as lenders sweeping gateway collections collect GST too. The choices come from the current GST rates on goods.
  • The 15% contribution margin (CM3) is an illustrative default — replace it with your own.
  • The first repayment is one month after the cash is received.
  • Repayments longer than 10 years are not shown.
  • The bank loan is the cash received, repaid in equal monthly instalments on a reducing balance over the same months, with no fees.
  • GST and tax effects of the fee are not modelled. Figures are rounded for display only; the working uses exact values.

How this is calculated

  1. Repayment cap = advance × (1 + flat fee %). Cash received = advance × (1 − upfront deduction %). Total cost = cap − cash received.
  2. Monthly sweep = monthly revenue × (1 + GST % added to the sweep base) × revenue share %. Months = cap ÷ sweep, rounded up; the last month repays only what is left.
  3. Weekly sweep = monthly sweep ÷ (52 ÷ 12). Weekly IRR as below, over weeks; APR = 52 × weekly IRR; EAR = (1 + weekly IRR)⁵² − 1.
  4. Share of contribution margin = monthly sweep ÷ (monthly revenue × CM3 %).
  5. Monthly IRR: the rate r at which the sum of each repayment ÷ (1 + r)ᵗ equals the cash received, found by 100 rounds of bisection.
  6. APR = 12 × monthly IRR. EAR = (1 + monthly IRR)¹² − 1.
  7. Bank EMI = P × i × (1 + i)ⁿ ÷ ((1 + i)ⁿ − 1), with P the cash received, i the yearly rate ÷ 12 and n the same months.
  8. Extra cost of RBF = RBF total cost − bank loan interest.

Worked examples

Example: a ₹50,00,000 advance at a 12% flat fee

2% deducted upfront; 14% of ₹80,00,000 monthly revenue swept.

  • Cap ₹56,00,000; cash received ₹49,00,000; total cost ₹7,00,000.
  • Sweep ₹11,20,000 a month for 5 months. Monthly IRR 4.6228%: APR 55.47%, EAR 71.99%.
  • Sales 40% higher: 3 × ₹15,68,000 + ₹8,96,000. Monthly IRR 6.0096%: APR 72.11%, EAR 101.44%.
  • A bank loan of ₹49,00,000 at 15% over 5 months: EMI ₹10,17,054.33, interest ₹1,85,271.66. RBF costs ₹5,14,728.34 more.

Example: the same offer, swept with GST

The same advance and sales, with a contribution margin (CM3) of 15%: ₹12,00,000 a month.

  • As entered: ₹11,20,000 a month, repaid in 5 months, taking 93.33% of the margin.
  • With 18% GST in the sweep base: ₹80,00,000 × 1.18 × 14% = ₹13,21,600 a month, repaid in 4.24 months, taking 110.13% of the margin — more than the business earns after marketing. APR 63.21%, EAR 85.15%.
  • Swept weekly instead: ₹3,04,985 a week for 19 weeks: APR 73.69%, EAR 107.87%.

Questions sellers ask

Why is the annual cost so much higher than the flat fee?

The fee is charged once on the whole advance, but you repay it within a few months, and you never have the full advance for the whole period. Spread over a short time and a falling balance, a flat 12% becomes a much higher rate a year.

Why does a better sales month make the financing more expensive?

The repayment cap is fixed. When sales rise, a larger share is swept each month, so the cap is repaid sooner. The same fee over fewer months is a higher rate a year.

What is the difference between APR and EAR?

APR is the monthly rate multiplied by 12. EAR also counts the effect of compounding, so it is higher. Both come from the same monthly rate; lenders usually quote APR.

How is the monthly rate (IRR) found?

It is the rate at which the monthly repayments, each discounted back to the day you received the cash, add up to exactly the cash received. There is no direct formula, so the tool narrows it down step by step (bisection) until it is accurate to well under a paisa.

What should the upfront deduction include?

Anything taken out of the cash paid to you: a processing or documentation fee, GST on that fee if you cannot claim it as input tax credit, and any amount held back. The more is deducted, the less cash you actually receive for the same repayments.

Is the bank comparison a real loan offer?

No. It is a loan of the same cash over the same number of months at the rate you enter, with equal monthly instalments on a reducing balance and no fees. Actual loans have their own fees, security and eligibility.
