- Formula
- Gross balance = deposit × (1 + annual rate/100/m)^(m × years), where m is compounds/year. Tax is deducted from the interest at maturity.
- Variables
- Deposit amount
- Annual interest rate
- Term
- Unit: Years, Months, Days
- Interest compounds: Daily, Weekly, Monthly, Quarterly, Every 6 months, Yearly
- Tax deducted on interest (optional)
- Start date
- Units
- Annual interest rate: %
- Tax deducted on interest (optional): %
- Use the same selected currency for all monetary inputs. Changing the symbol does not convert exchange rates.
- Example
- 500,000 at 10% for 3 years with quarterly compounding grows to about 672,444, earning 172,444 in interest. That is an effective yield of about 10.38% a year.
- Assumptions

Methodology & References
The method depends on the selected model and input options. Review the assumptions and references above before interpreting the result.
- Enter the deposit amount, annual interest rate and term.
- Choose how often interest compounds and, optionally, the tax rate on profit.
- Pick the start date to see the maturity date and how your balance grows.
Interpretation and limitations
- Why does an STDR earn more than a TDR? Because interest is added to the deposit, it earns interest itself in later periods. Over longer terms this compounding makes a noticeable difference.
- Does compounding frequency matter? More frequent compounding gives slightly more. At 10%, quarterly compounding yields about 10.38% a year and monthly about 10.47%.
- Can I withdraw an STDR early? Most banks allow early withdrawal but pay a lower rate or charge a penalty. Check your bank's terms.
