How loan repayments work
A standard loan is repaid in equal monthly instalments over its term. Early on, most of each payment is interest; over time, more goes to the principal. This calculator uses the standard amortisation formula on the amount, annual rate and term you enter, and shows what you’d repay each month, how much interest you’d pay in total, and the total cost of the loan.
It’s a great way to compare scenarios — see how a lower rate or a shorter term changes the monthly cost and the total interest. Just remember real loans add fees, and rates can change.
