This calculator models equal monthly payments on a fully amortising loan using the amount, term and nominal annual rate you enter. It assumes the rate stays fixed and every payment is made on time. Actual business finance may use different calculations and include fees, deposits, final payments, variable rates or non-monthly collections.

What the result assumes

  • The full amount entered is advanced at the beginning.
  • There are 12 equal payments per year, made monthly in arrears.
  • The entered annual interest rate stays fixed for the entire term.
  • Interest is calculated monthly on the outstanding balance.
  • No arrangement, broker, legal, valuation, late or early-settlement fees are included.
  • There is no deposit, interest-only period, balloon or final purchase payment.
The entered rate is not a quote. The calculator does not select a rate, test affordability or estimate whether a lender will approve your company. Use the actual payment schedule and all fees from a written proposal.

Why the total may differ from an offer

Business-loan agreements can use flat rates, effective rates, variable rates or collection structures that are not equal monthly repayments. Fees may be paid upfront, deducted from the advance or added to the balance. The amount your company receives can therefore differ from the amount on which charges are calculated.

Compare the result properly

  1. Replace the example rate with the rate stated in the proposal.
  2. Add every fee and confirm whether it is financed or paid separately.
  3. Check the amount the company actually receives.
  4. Compare payment dates with the company's cash-flow cycle.
  5. Read security, personal-guarantee and early-settlement terms.
  6. Stress-test the payment against a weaker trading month.

See the business-loan guide for the wider route and document checklist. The growth-finance guide explains how to test the payment inside a costed expansion plan.

Frequently asked questions

Does the calculator show APR?

No. It uses the nominal annual interest-rate assumption you enter and excludes fees. APR or another effective cost measure may differ.

Does the result include fees?

No. Add all arrangement, legal, valuation, broker and other charges from the written proposal when comparing the real cost.

Is the result an offer of finance?

No. It is an illustration only. Availability, rate, amount and terms depend on the provider's assessment and agreement.
