🏦 Loan Calculator

What This Calculator Does

This calculator estimates the monthly payment on a loan, along with the total you will pay over its life and how much of that is interest. Enter the loan amount, the interest rate, and the term, and it breaks down what the loan really costs. It works for personal loans, auto loans, and other fixed-rate, fixed-term borrowing, turning the abstract numbers of a loan offer into figures you can actually plan around.

A loan's headline figures — the amount and the rate — do not by themselves tell you what it costs you each month or in total. This calculator fills in that gap, so before you commit you can see the monthly payment your budget has to absorb and the full price of borrowing, including all the interest.

How Loan Payments Work

A fixed-rate loan is repaid in equal monthly installments over its term. Each payment covers two things: the interest accrued that month, and a portion of the original amount borrowed (the principal). Early in the loan, more of each payment goes toward interest because the balance is large; as the balance shrinks, more goes toward principal. This process is called amortization, and it is why the total interest you pay depends heavily on the term length.

Two factors drive the cost. A higher interest rate raises both your monthly payment and the total interest, as you would expect. The term length is more subtle: a longer term lowers the monthly payment, which can look attractive, but it means paying interest for more years, so the total cost is higher. A shorter term raises the monthly payment but saves substantially on total interest. The calculator lets you see this trade-off directly by adjusting the term and watching how the monthly and total figures move in opposite directions.

Quick Tips

• A longer term lowers the monthly payment but increases the total interest you pay.
• Compare loan offers by total cost, not just the monthly payment.
• Even a small difference in interest rate can add up to a large difference over the full term.
• Remember the estimate covers principal and interest; fees may add to the real cost.

Frequently Asked Questions

How is a monthly loan payment calculated?

It is based on the loan amount, the interest rate, and the term, spread into equal monthly installments through a process called amortization. Each payment covers that month's interest plus a portion of the principal.

Why does a longer term cost more overall?

Because you pay interest for more years. A longer term lowers each monthly payment but increases the total interest, so the loan costs more in total even though it feels easier month to month.

Should I compare loans by monthly payment or total cost?

By total cost. Two loans with similar monthly payments can differ greatly in total interest. Looking at the full cost reveals which loan is genuinely cheaper.

Does this include fees?

No. The estimate covers principal and interest. Real loans may include origination fees or other charges, so confirm the full terms with the lender for an exact figure.
