How Loan Payments Are Calculated

This calculator uses the standard amortization formula: each monthly payment covers that month's interest charge plus a portion of the principal. Early payments are mostly interest; later payments are mostly principal. The total payment stays the same every month.

Shorter Term vs Longer Term

A shorter loan term means higher monthly payments but much less interest paid overall. A $25,000 loan at 6% costs about $466/month over 5 years (total interest: $2,967). The same loan over 3 years costs $760/month but only $1,759 in interest — saving over $1,200. If you can afford the higher payment, shorter is almost always better.

Frequently Asked Questions

What is a good interest rate for a personal loan?+
Personal loan rates vary widely by credit score. Excellent credit (720+): 6–12%. Good credit (680–719): 12–18%. Fair credit (640–679): 18–28%. Poor credit: 28%+. Rates below 10% are generally considered good for personal loans. Always compare at least 3–4 lenders before accepting an offer.
Should I pay off my loan early?+
Usually yes — paying extra reduces the principal faster, which means less interest accrues over time. However, check whether your loan has a prepayment penalty first (some lenders charge a fee for early payoff). Also consider opportunity cost: if your loan rate is 5% but you can earn 7% investing, it may be better to invest the extra money instead.
What happens if I miss a loan payment?+
Missing a payment typically results in a late fee (usually $25–50), and after 30 days it will appear on your credit report, damaging your credit score. After 90+ days, the lender may send the account to collections. If you're struggling, contact your lender before missing a payment — many offer hardship programs or deferment options.
How does my credit score affect my loan rate?+
Your credit score is the single biggest factor in the rate you're offered. A difference of 100 points in your credit score can mean 5–10% difference in your interest rate, which translates to thousands of dollars over the life of a loan. Before applying for a major loan, it's worth spending 3–6 months improving your score by paying down balances and fixing any errors on your credit report.
