Loan Term

The loan term is the scheduled lifespan of a loan — 30 years on the classic mortgage, 3–7 on car loans, 10 on standard federal student plans. It’s the quietest of the three numbers that define a loan (amount, rate, term), and often the most expensive one.

The mechanics: a longer term spreads principal repayment across more payments, so each payment is smaller — but the balance survives longer, generating interest the whole time. The totals diverge dramatically. A $300,000 mortgage at 6.5% costs about $1,896/month over 30 years with ~$383,000 of total interest; the 15-year version costs about $2,613/month with ~$170,000 of interest. The shorter term’s payment is 38% higher; its lifetime interest is 56% lower.

Lenders and dealers exploit the asymmetry: stretching the term is how an unaffordable price becomes an “affordable” payment. Seven- and eight-year car loans exist mostly to sell more expensive cars; extended student plans lower payments while multiplying interest.

The honest way to choose: pick the shortest term whose payment fits your budget with margin — or take the longer term for safety and prepay it like the shorter one (see amortization). Compare any pair of terms in the mortgage calculator.
