Estimate your loan repayments by amount, rate, term and frequency — and see what total interest the structure really costs over the life of the loan.
What this calculator estimates
The Repayment Calculator turns a loan into the number that actually matters month to month: what it costs you to hold and repay it. Enter the loan amount, the interest rate you expect, the term, and how often you pay, and the tool returns an indicative repayment alongside the total interest and total cost over the life of the loan. Switch between principal & interest and interest only to see how the choice changes the figure — and what the interest-only repayment reverts to once that period ends.
What drives the number
Three things move a repayment: the size of the loan, the rate, and the term you spread it over. A longer term lowers each repayment but lifts total interest, often substantially. Interest only keeps repayments down while you hold the asset, but the balance does not reduce, and the loan eventually reverts to principal & interest at a higher repayment. None of this is a lender's verdict — it is arithmetic you can plan around. The real question is how the loan is structured: the term, the repayment type, and which lender's policy lets you build it that way.
Use it as a starting point
Treat the result as a planning figure, not a quote. The headline rate is only part of the cost, and the right structure can matter more than a small rate difference. Book a strategy session and we will model the repayment against your real position and the way you intend to use the loan.
