Equal payments or equal principal?

With equal payments (an annuity, the usual mortgage) every monthly payment is the same; early payments are mostly interest and later ones mostly principal. With equal principal you repay the same slice of principal every month plus that month’s interest, so the first payments are the largest and they shrink over time. Equal principal costs less interest in total but needs more cash at the start.

What is an interest-only period?

For the first months you only pay interest and the balance does not go down. Here the interest-only months count inside the term, so a 30-year loan with 36 interest-only months is repaid over the remaining 27 years, which makes the later payments higher and the total interest larger.

Why does my lender’s figure differ slightly?

Lenders round each payment to the currency unit, may count interest by days rather than months, and may add fees or insurance. This calculator uses the annual rate ÷ 12 per month and rounds only for display, so results can differ by a few units.
