Simple Interest Worksheets by Christopher Rudolph

Alright, let’s break down simple interest, a fundamental concept in math that’s quite handy in understanding how money grows over time.

Imagine you have some money, let’s call it the principal. The principal is like the seed money you start with when you plant a financial seed. Now, when you put that money into a savings account or lend it to someone, you usually expect to get a little extra back over time, right? That extra bit is the interest.

Here’s where the three amigos come in: principal, rate, and time. The principal is the amount of money you start with. The rate is how much interest you earn on that money as a percentage. And time is, well, time – how long your money stays in the account or is lent out for.

So, how do we calculate simple interest? It’s as easy as pie! Literally, it’s Principal × Rate × Time (expressed as a fraction of a year). Here’s the formula:

Simple Interest = Principal × Rate × Time

Let’s say you have $100 (that’s your principal), and you’re getting an annual interest rate of 5%. If you leave that money for one year, the simple interest would be:

Simple Interest = $100 × 5% × 1 = $5

That means you’d earn $5 in interest for leaving your $100 untouched for a year. But let’s say you leave it for two years:

Simple Interest = $100 × 5% × 2 = $10

See how it doubled? That’s because time is a multiplier here. The longer you leave your money, the more interest you earn.

And voila! You’ve just unlocked the secret to calculating simple interest. It’s a neat little tool that helps you understand how your money can grow over time, simply by sitting in an account or being lent out.

These printable Simple Interest Worksheets use simple annual interest to solve word problems. Each worksheet has 10 simple interest word problems. Students calculate interest based on principal, rate, and time. Each worksheet comes with a printable answer page. Teachers, parents, and students can print these out and make copies.
