The numbers for $15,000 over 48 months

At 8% a year the monthly rate is 0.006667 and four years gives n = 48 payments.

Forty-eight payments of $366.19 come to about $17,577.30. With a $15,000 principal, total interest is roughly $2,577.30 — some 14.66% of the total repayment. That means around 14.7 cents of every dollar you pay is the cost of borrowing.

Reading the result

• The 48-month term is a genuine sweet spot: notably cheaper than five or six years, yet far lighter on the wallet than three.
• At three years the same $15,000 costs only about $1,904 in interest, but the payment jumps to roughly $470.
• At six years the payment falls to about $263, but interest climbs past $3,900.
• Because interest is charged on the outstanding balance, the first payments are interest-heavy and the last ones almost entirely principal.

When four years makes sense

Choose this profile when you want a payment near $366 that stays predictable for the whole term. It suits a car purchase where you expect to keep the vehicle well beyond the loan, or a home renovation that adds lasting value. If cash flow is tight, a longer term eases the monthly burden, but remember that every extra month is extra interest — the four-year option already balances the two reasonably well.
