Example 1 — 3 years at 5%
- Capital: 10,000
- Rate: 5%
- Years: 3
Interest 1,500
Final 11,500
Simple 5% × 3 years = 15% of capital.
Savings interest
Estimate earnings from simple interest at an annual rate over years — educational model, not a bank term deposit.
Simple interest: gain = capital × rate × years. Differs from a term deposit (months, product framing, optional tax) and from compound interest (no compounding here). Educational estimate. Amounts follow the header currency.

How results are calculated
Interest = capital × (rate/100) × years. Final = capital + interest. No compounding — interest does not join the base.
How to use the calculator
- Enter capital in the header currency.
- Enter the annual interest rate (%).
- Set the term in years.
- Read interest earned and the final amount.
Usage examples
Example 2 — One year at 4%
- Capital: 25,000
- Rate: 4%
- Years: 1
Interest 1,000
Final 26,000
One year of simple interest — an easy reference point.
Example 3 — 5 years at 6%
- Capital: 5,000
- Rate: 6%
- Years: 5
Interest 1,500
Final 6,500
Without compounding — compound interest would earn more at the same rate.
FAQ
What do savings interest results mean?
Estimated earnings on capital at the stated rate and term — gross or net depending on the form fields. Amounts in the header currency.
When does this model fit a deposit or savings account?
When the rate is known up front and compounding matches what you enter (or a simple term without frequent compounding).
Which assumption can be too optimistic?
A fixed rate for the whole period and no withdrawals. Promotional rates can fall, and withdrawals stop accrual.
What mistake understates net yield?
Comparing a gross rate to peers without interest tax, or mixing days with months for the term.
How does this differ from a term deposit?
Here the term is in years and the model is educational simple interest. The deposit tool uses months and an optional withholding field like a term product.
How does this differ from compound interest?
There is no compounding here — interest does not join the base. Compound interest shows interest-on-interest.
Which related tools help?
Deposit gain, compound interest, and capital-gains withholding — to move from simple yield to a bank product or tax.
When should you not use it?
When the product compounds frequently or offers differ in compounding frequency — use compound interest instead.
