Mathematical Formula & Method
Simple Interest Calculator Formula
SI = (P × R × T) / 100 | Total Amount = P + SI
Worked Examples & Step-by-Step Solutions
$10,000 at 7.5% for 3 years
- SI = (10,000 × 7.5 × 3) / 100 = 2,250.00.
- Total Maturity Amount = 10,000 + 2,250 = $12,250.00.
How to Use the Simple Interest Calculator
- Enter principal, interest rate, and duration in years.
Important Assumptions & Unit Conventions
