Compound Interest Calculator

Enter values to compute.

Principal p

Rate r

Time t

Compounds per Year n

Understanding the Math

The Compound Interest Calculator computes the result using fundamental principles of mathematics. Calculate compound interest over a specific period.

Formula Definition

Result = p × pow((1 + (r÷100)÷n), (n×t)) - p

This formula is applied directly to the inputs provided above. Ensure all units are consistent (e.g., all lengths in meters) before calculation to guarantee accuracy.

Example Problem

Given:

Principal = 15
Rate = 8
Time = 11
Compounds per Year = 13

Solution:

Substitute values into the formula:

Result = 15 × 15ow((1 + (8÷100)÷13), (13×11)) - 15

Quick Notes

Double-check input units. Inconsistent units (e.g. feet vs meters) will yield incorrect results.
Calculations are performed with high-precision floating point arithmetic.
