Principal vs Interest
About this calculator
Loan interest is calculated on the outstanding balance. With a fixed monthly payment (amortization), early payments contain more interest and less principal — as the balance falls, that ratio gradually shifts. APR (Annual Percentage Rate) includes fees in addition to the interest rate, making it a more accurate comparison metric than the stated rate alone.
The total interest figure in the results shows the true cost of borrowing over the full loan term. Choosing a shorter repayment term reduces total interest significantly, though it increases monthly payments. Running different term scenarios helps clarify the trade-off between monthly affordability and long-term cost.
