Simple Interest Calculator Explained
A simple interest calculator shows how much interest builds up when interest is calculated only on the original principal. You enter the starting amount, annual rate, and time period, and the tool returns the interest earned plus the final amount. This is useful for basic loans, classroom examples, short-term savings, and quick comparisons where compounding does not apply. It is easier to understand than compound growth because the interest stays linear over time, which makes it a good starting point for beginners learning how rates affect money.
