The unpaid balance method is a way lenders use to calculate interest.
First, they subtract your payment from your previous balance. Then they apply interest to the remaining amount.
This method can lower your finance charges because interest is charged only on the balance left after your payment.
Many credit card companies and lenders use this method to calculate finance charges.
The formula for unpaid balance is:
Unpaid Balance = Previous Balance + Interest − Payments Made + Additional Purchases
Where:
Interest Formula
Interest = Previous Balance × Monthly Interest Rate
Monthly Interest Rate Formula
Monthly Interest Rate = APR ÷ 12 ÷ 100
For loans and mortgages, the unpaid principal balance formula is:
Unpaid Principal Balance = Original Loan Amount − Total Principal Paid
This formula shows how much of the original loan amount is still unpaid.
Using our calculator is very easy.
The calculator will show your unpaid balance and finance charge instantly.
Suppose you have the following values:
Step 1: Convert APR to Monthly Rate
Monthly Rate = 24 ÷ 12 ÷ 100 = 0.02
Step 2: Calculate Interest
Interest = $1,000 × 0.02 = $20
Step 3: Calculate Unpaid Balance
Unpaid Balance = $1,000 + $20 − $300 + $150
Unpaid Balance = $870
Your remaining unpaid balance is $870.
Suppose:
Step 1: Find Remaining Balance
Remaining Balance = $800 − $200 = $600
Step 2: Calculate Finance Charge
Finance Charge = $600 × 0.015 = $9
Your finance charge is $9.
