## Inputs

- **Loan Amount** ($) — min 0 — The total amount you plan to borrow.
- **Annual Interest Rate** (%) — min 0, max 50 — The yearly interest rate on your loan.
- **Loan Term (months)** — min 1, max 600 — The length of the loan in months (e.g. 60 for 5 years).

## Outputs

- **Monthly Payment** — formatted as currency — Your fixed monthly payment.
- **Total Interest Paid** — formatted as currency — Total interest paid over the life of the loan.
- **Total Cost of Loan** — formatted as currency — Total of all payments (principal + interest).

## Details

Loan payments are calculated using the same amortization formula as mortgages: M = P[r(1+r)^n] / [(1+r)^n - 1], where P is the principal amount, r is the monthly interest rate, and n is the total number of monthly payments. This produces fixed monthly payments where early payments are more interest-heavy, and later payments go mostly toward principal.

Common loan types include auto loans (typically 3-7 years at 4-10%), personal loans (1-7 years at 6-36%), and student loans (10-25 years at 3-8%). The interest rate you receive depends on your credit score, income, debt-to-income ratio, and the lender.

To reduce total interest paid, consider making extra payments toward the principal, choosing a shorter loan term, or refinancing if rates drop. Even small additional monthly payments can shave months or years off your loan and save hundreds or thousands in interest.

Always compare the total cost of the loan (principal plus all interest) rather than just the monthly payment. A lower monthly payment over a longer term often results in significantly more total interest paid.

## Frequently Asked Questions

**Q: How are monthly loan payments calculated?**

A: Monthly loan payments are calculated using the standard amortization formula: M = P[r(1+r)^n] / [(1+r)^n - 1], where P is the principal loan amount, r is the monthly interest rate (annual rate divided by 12 and by 100), and n is the total number of monthly payments. This formula produces equal monthly payments that fully pay off the loan by the end of the term.

**Q: What is the difference between APR and interest rate?**

A: The interest rate is the cost of borrowing the principal amount. The APR (Annual Percentage Rate) includes the interest rate plus other fees and costs associated with the loan, such as origination fees, closing costs, and discount points. APR gives you a more complete picture of the true cost of borrowing. This calculator uses the interest rate only; your APR may be slightly higher.

**Q: How does loan term affect my total cost?**

A: A shorter loan term means higher monthly payments but significantly less total interest paid. A longer term lowers monthly payments but increases total cost. For example, a $25,000 loan at 7.5%: over 36 months you pay $2,937 in total interest with a $776/month payment, but over 60 months you pay $4,952 in total interest with a $500/month payment. The shorter term saves over $2,000.

**Q: Should I pay off my loan early?**

A: Paying off a loan early can save significant money in interest. However, some loans charge prepayment penalties. Check your loan agreement first. If there is no penalty, making extra payments toward principal is almost always beneficial. Even adding $50-100 per month to your payment can cut months off the loan and save hundreds in interest.

**Q: What credit score do I need for a good loan rate?**

A: Generally, a credit score of 740 or higher qualifies for the best loan rates. Scores between 670-739 typically get good rates. Below 670, rates increase significantly, and below 580, you may have difficulty qualifying for traditional loans. Improving your credit score before applying can save thousands in interest over the life of a loan.
