Guide
How it works
Use this calculator to estimate a simple annual percentage rate based on loan amount, finance charges, and loan term. It helps you understand how fees and charges can affect the annualized cost of borrowing.
What this calculator does
The APR calculator estimates borrowing cost as an annual percentage.
It uses:
- loan amount
- finance charges
- loan term in years
- simplified APR calculation
The result shows an estimated APR. This is a simplified planning estimate, and lender APR calculations may differ.
How to use the APR calculator
Enter the amount borrowed, total finance charges, and loan term in years. Finance charges may include fees, interest charges, or borrowing costs you want to annualize.
Use this calculator to compare broad borrowing cost, then check lender disclosures for the official APR.
APR Formula
Estimated APR = finance charges / loan amount / loan term x 100
This simplified formula spreads finance charges evenly across the loan term.
Example calculation
If:
- Loan amount = 10,000
- Finance charges = 1,500
- Loan term = 3 years
- Calculation basis = annualized
Then:
Estimated APR = 1,500 / 10,000 / 3 x 100 = 5%
The estimated APR is 5.00%.
What is APR?
APR stands for annual percentage rate. It is intended to show the annual cost of borrowing, often including interest and certain fees.
APR can be more useful than interest rate alone because it may capture more of the total borrowing cost.
Interpreting your result
Use the result as a rough comparison tool. Official APR can use required legal methods, compounding assumptions, and fee treatment that this simplified calculator does not reproduce.
When to use this calculator
