How do lenders calculate personal loan interest?
Our calculator mirrors the way lenders calculate and charge interest on a personal loan. Interest is calculated daily on your current loan balance and charged monthly.
Here’s an example:
- Loan: $20,000 at a fixed rate of 7% p.a.
- Annual interest: $20,000 x 0.07 = $1,400
- Daily interest: $1,400 ÷ 365 = $3.84
- Monthly interest (31 days): $3.84 x 31 = $119.04
- This amount is added to your loan balance and repaid along with the principal
How personal loan repayment calculations work

Our personal loan calculator uses something called “amortisation” to work out your repayments. This just means your loan balance goes down over time as you pay it off.
Each repayment covers two things:
- Interest charged by the lender
- The amount you borrowed (the principal)
At the start, more of your repayment goes toward interest because your loan balance is higher. As the balance gets smaller, you pay less interest and more off the principal.
