What is Simple Interest?
Simple interest is a quick method of calculating the interest charge on a loan or the interest earned on a deposit. Unlike compound interest, simple interest is calculated only on the initial principal amount.
The Simple Interest Formula
The standard mathematical formula used by this tool is:
SI = (P × R × T) / 100
- P = Principal Amount (The initial money)
- R = Rate of Interest per annum (%)
- T = Time Period (in Years)
If you select "Months" in our tool, we automatically convert the time to years (Time / 12) before applying the formula.

Frequently Asked Questions (FAQs)
1. Does this calculator work for days?
Currently, this calculator supports Years and Months. To calculate for days, you can convert your days into a fraction of a year (Days / 365) and enter that value in the "Time" field while selecting "Years".
2. What is the difference between Simple and Compound Interest?
Simple interest is calculated on the principal amount only. Compound interest is calculated on the principal amount plus the interest that has accumulated over previous periods. Compound interest grows faster over time.
3. Can I use this for bank loan calculations?
Yes, you can use it for estimates. However, banks often use specific day-count conventions or compound interest methods. This tool provides a mathematical simple interest figure.
