Loan Interest Calculator
Estimate simple interest for a specified principal, rate and period.
Simple interest
An illustration based on your inputs, not a quote or recommendation.
Read the formula and assumptions below before making a decision.
Loan Interest: worked example
This is an illustrative scenario using the default inputs, not your personal result. Amounts use AED for illustration; the general formula also accepts your own figures in the selected currency.
| Input | Example value |
|---|---|
| Principal | AED 50,000.00 |
| Annual simple interest rate | 7% |
| Period in months | 12 months |
Simple interest: AED 3,500.00
- Principal plus interest: AED 53,500.00
Before you use this estimate
Use this tool for simple interest over a period. Use the personal loan repayment tool for a loan whose principal falls with monthly payments.
Is simple interest the same as interest on a repayment loan?
Not usually. This model keeps the entered principal unchanged for the interest period. An amortising loan recalculates interest as principal is repaid.
How the calculation works
Assumptions & limitations
This is a simple-interest model, not a reducing-balance repayment schedule or an APR calculation.
Use the result thoughtfully
Try a second scenario to see how a change in costs, timing or contributions affects the result. Keep all amounts in one currency and use consistent periods. Confirm important figures against your own records before acting.
