How repayment loans work
With a repayment loan, each monthly payment covers interest and a portion of the original capital. Early payments are mostly interest; later payments are mostly capital.
With an interest-only loan, you pay only the interest each month. The capital must be repaid separately at the end of the term.
The calculator uses the standard annuity formula for repayment loans: M = P × [r(1+r)^n] / [(1+r)^n - 1].
