Why the amortization table matters
A loan can look affordable month to month while still becoming expensive overall. The amortization schedule shows where your money goes each month so you can see how quickly the balance actually drops.
The main outputs are monthly payment, total interest, and total repayment. Use all three together before comparing loan options.
Loan payment formula and example
This calculator uses the standard fixed-payment formula: Payment = P x r x (1 + r)^n / ((1 + r)^n - 1). P is loan principal, r is monthly rate, and n is total months.
Example: a $50,000 loan at 5% annual interest for 5 years has an estimated monthly payment of about $943.56 and total interest of about $6,613.70.
Assumptions, use cases, and common mistakes
Use this page to compare loan terms, estimate affordability, and see how interest changes with rate and term. Results are estimates, not lender offers.
- Do not compare loans using monthly payment alone; total interest and fees matter.
- Do not treat nominal interest rate as APR if fees are part of the loan.
- Do not assume a fixed schedule for variable-rate or balloon-payment loans.
- Verify decisions with lender statements, bank documents, official calculators, or a qualified professional.

Frequently Asked Questions
Common questions about Loan Calculator and how to read the result.
What if my rate changes later?
This calculator assumes a fixed rate for the full term. Variable-rate loans will change the schedule and total interest over time.
What does monthly payment include?
The monthly payment shown here includes principal and interest only. Fees, insurance, taxes, penalties, and lender conditions are not included.
How is total interest calculated?
Total interest is estimated by multiplying the monthly payment by the number of months, then subtracting the original loan principal.
Is interest rate the same as APR?
Not always. APR may include certain fees and borrowing costs, while this loan calculator uses the annual interest rate you enter.
Why does a shorter term reduce interest?
A shorter term usually repays principal faster, so interest has less time to build, though the monthly payment is often higher.
Is this loan result financial advice?
No. It is a planning estimate. Confirm loan costs, fees, terms, and eligibility with the lender or a qualified professional.
