A loan calculator turns three familiar numbers into a practical repayment estimate. Use it to compare scenarios before you apply, then confirm the final figures with your lender.
What a loan calculator shows
The calculator estimates a regular payment from the amount borrowed, annual interest rate and repayment term. It also shows total payments and the interest paid across the term.
A longer term can reduce the monthly payment while increasing total interest. A lower rate can reduce both the monthly cost and the lifetime cost of borrowing.
How to enter your numbers
Enter the amount you expect to borrow as the principal. Use the annual percentage rate offered to you and enter the full term in years. Keep the units consistent so the estimate is meaningful.
- Compare the same principal across lenders.
- Test a shorter term to see the interest trade-off.
- Add taxes, insurance or fees separately when they apply.
Example loan calculation
For a 20,000 loan at 6% over five years, the monthly principal-and-interest estimate is about 386.66. The actual offer can differ because lenders may include fees, compounding rules or insurance.
Frequently asked questions
Does a loan calculator include lender fees?
CalcCove's basic loan estimate covers principal and interest. Add lender fees, taxes or insurance separately when comparing the full cost.
Why does a longer loan term cost more?
A longer term spreads payments over more months. That can lower each payment but usually gives interest more time to accumulate.
