Simple Interest Calculator
A simple-interest calculator finds interest charged only on the original principal, not on accumulated interest. Enter principal, rate and time to see the interest and total amount — the method used for many short-term and vehicle loans.
How is Simple Interest calculated?
SI = P × r × t / 100; total = P + SI.
