Annuity / equal installments
A repayment method in which every monthly payment is the same amount, principal and interest together, as long as the rate stays the same.
Early payments are mostly interest; the principal share grows over time. When the rate changes, for example when the promotional period ends, the bank recalculates the equal payment for the remaining term.
Total interest is higher than with a declining balance, but the first payment is lower and easier to budget for. The calculator offers both methods.
