## Overview

Choosing a 5-year term on a $20,000 loan at 11% cuts the monthly payment to about $435, around $220 lighter than the 3-year plan. The relief comes at a price: total interest climbs to roughly $6,091 — nearly $2,500 more than the faster payoff — for a total repaid near $26,091. It is the longest standard term for a mid-sized personal loan.

## Method

The calculator uses the standard level-payment amortization formula. The periodic payment M equals P times r times (1 + r) to the power of n, divided by ((1 + r) to the power of n minus 1), where P is the loan principal, r is the interest rate per period (the annual rate divided by the number of periods per year), and n is the total number of payments. For a monthly loan r is the annual rate divided by 12; for fortnightly it is divided by 26. When r is zero the formula degenerates and M is simply P divided by n. The amortization schedule is then built period by period: interest for each period is the remaining balance multiplied by r, the principal portion is M minus that interest, and the balance is reduced accordingly until it reaches zero on the final payment.
