Useful for longer-term fit
Model whether the monthly load still works after payroll, rent, inventory, and existing debt are taken into account.
Calculator
This calculator solves for the missing variable, builds the amortization, and shows the numbers borrowers usually underestimate: the payment, the total interest, and how long the cash flow has to carry the debt.
Model whether the monthly load still works after payroll, rent, inventory, and existing debt are taken into account.
Term length and amortization can change business strain just as much as the nominal rate.
A calculator can tell you whether the debt fits. It cannot decide whether term, SBA, LOC, or equipment finance is the better product family.
Select the field you want solved, then enter the other three. The calculator updates the answer, total repayment, total interest, and the amortization schedule automatically.
Select the field to solve for. The other three values must describe a realistic loan structure.
Use the requested or quoted principal balance.
Annual nominal rate. Leave it as the solved field if you want to back into the implied pricing.
Use decimal years when needed. Example: `2.50` for a 30-month term.
Usually the most useful solve target when a borrower wants to know if the debt actually fits.
| Month | Payment | Principal | Interest | Balance |
|---|
Interpret the result
The payment still has to compete with payroll, rent, inventory, taxes, and any existing debt. If the monthly number only works in a best-case month, the structure is probably too aggressive.
Advisor lens
Clear use of proceeds, stable monthly cash flow, and a repayment horizon that does not force the business into renewal mode are usually good signs for a term structure.
If the payment only works in peak months, or the total interest starts crowding the project return, I would compare LOC, SBA, equipment finance, or a smaller request.
Recent financials, current debt schedule, and a credible explanation of how the capital improves the business usually matter more than trying to maximize the ask.
