This models a fully amortising loan with a fixed rate and monthly repayments. It excludes fees, balloon payments, redraws, rate changes and lender-specific rounding.

Go beyond one formula

Test debt repayments inside the full business model.

The industry simulator connects pricing, volume, staffing, rent, setup costs, break-even, payback, cash flow and risk.

Amortising repayments

The payment stays level while its composition changes.

Early payments contain more interest because the outstanding principal is higher. More of each later payment reduces principal as the balance falls.

Rate and term

A longer term lowers payments but can increase total interest.

Compare both the regular repayment and total financing cost. A payment that looks manageable can still be expensive when spread over more months.

Compare with lender figures

Fees and loan structure matter.

Establishment fees, ongoing charges, compounding conventions, variable rates, repayment timing and balloon amounts can change a lender's schedule. Check the contract.
