How much startup financing do you need, and can you repay it?
Borrowing needs to solve both a funding gap and a payment-timing problem. Begin with the verified use of funds, deduct committed usable money, then test the proposed repayments against cash available after operating commitments. A larger loan does not repair an operating loss.
What you will produce: A sources-and-uses brief, a net funding gap and a repayment scenario to discuss with a lender.

What to have ready
Bring the opening budget, weekly cash plan, committed owner contribution and the actual terms of any financing offer. The rate below is an authored illustration, not a current market or SBA program rate.
Work through the calculation and decision
What belongs in a financing brief?
Describe the business format, the amount requested and exactly what each part funds. Connect equipment to a quote, premises work to a defined scope and working capital to a dated cash deficit. Identify the owner contribution, its availability date and any conditions attached to other funds.
Present base and downside cash schedules with the repayment included. Explain what changes under slower sales, delayed opening or slower collections. Keep the supporting evidence next to the input it supports so a reader can trace the requested amount without reconstructing the whole plan.
Why are gross borrowing and usable cash different?
A lender may deduct fees from proceeds or require payments outside the loan. Record the gross obligation separately from the cash actually available to pay suppliers. Compare offers using proceeds, payment dates, total payments, fees, collateral, guarantees and any variable-rate or balloon provisions.
The exercise assumes a fixed nominal annual rate, equal monthly end-of-period principal-and-interest payments and no balloon. Divide the annual rate by 12 for the monthly rate. At zero interest, the monthly payment is principal divided by the number of payments. Fee withholding changes usable proceeds, while interest here is calculated on gross principal.
What makes a repayment plan credible?
Use cash available before this proposed loan payment, after the operating costs and existing obligations represented in your forecast. Compare the payment with each relevant period, not only the strongest mature month. A positive average can conceal a shortfall during the opening ramp.
The comparison is a planning test, not a lender eligibility ratio. A lender may apply its own definitions and requirements. Record what remains subject to approval and avoid describing an application, indication of interest or headline borrowing limit as committed funding.
A $50,000 loan leaves only $49,000 to use
This authored example assumes 12% nominal annual interest, 36 monthly payments and $1,000 withheld in fees.
| Item | Illustrative result |
|---|---|
| Gross obligation | $50,000 |
| Usable proceeds | $49,000 |
| Monthly principal-and-interest payment | About $1,660.72 |
| Opening requirement | $70,000 |
| Other committed funds | $20,000 |
| Remaining funding gap | $1,000 |
| Cash available before this repayment | $2,500 per month |
| Cash after this repayment | About $839.28 per month |
What this changes: The loan covers less of the opening requirement than its headline amount suggests. The positive monthly remainder also needs testing during the weakest weeks. Neither result establishes approval or affordability for an actual borrower.
Compare the payment with cash available to repay
Start with the illustrative example, then replace its inputs with your own assumptions. All money amounts are in USD. The result updates in this tab.

This fixed-rate illustration assumes equal monthly end-of-period payments, no balloon, and fees withheld up front. It is not an APR calculation, lender quote or credit approval.

Errors that can change the result
- Counting the gross loan amount as net usable cash.
- Treating a repayment calculator as an approval decision.
- Funding recurring operating losses without changing their cause.
