Choose the formula that matches the contract
Each tab mirrors a specific loan product structure. Select the one that matches the agreement you are pricing — not the product that sounds closest. A term loan and a revenue-based advance use entirely different math; mixing them produces a misleading result.
Uses standard monthly amortization and treats the selected fee as withheld from proceeds while the full principal is still repaid. Each payment reduces the outstanding balance at a declining interest charge, so total interest falls the faster you pay it down.
Estimates one constant draw, not repeated borrowing. Interest is calculated on the drawn balance for the full period it stays outstanding, plus any allocated facility fee, so it shows the true cost of holding that single draw.
Calculates the purchased or payback amount and average weekly remittance without presenting a factor rate as an APR. The total payback is fixed at signing, so it does not fall if you repay early or if sales slow down.
Separates the initial advance, the reserve held back and a time-based fee, so you can see true net proceeds instead of the invoice face value. The reserve returns once your customer pays, minus the fee for the days it took.
Compares annual cash available for debt service against existing and proposed payments. Run this one first — if the coverage ratio fails at the rate and term you are considering, the rest of the shopping trip may be wasted effort.
Run a downside case. Keep the result beside the contract.
A payment that covers comfortably against average revenue can create a cash flow problem in a slow month. These steps take under five minutes.
After calculating the expected payment, test the same amount against your weakest recent month, not the average one. For variable-rate debt, rerun it at a higher benchmark; for invoice finance, rerun it with slower customer payment.
Check whether the fee in your proposal is withheld from proceeds or added to the balance. A $3,000 fee withheld from a $150,000 loan means $147,000 arrives while you still repay $150,000 plus interest — a very different cost than it looks on paper.
Save your inputs, the calculation date and the written offer together, then line up net cash received, total dollars repaid, payment frequency and default terms against what the paperwork actually says.
These calculators are educational planning tools, not approval estimates, legal advice or lender quotes. Compare at least two written offers before accepting any proposal.
