If your students can calculate amounts using compound and simple interest and are confident comparing the two, then they are ready for our series of compound interest problem solving questions.
This worksheet will see pupils working over three different sections to find the time period, the initial investment or the interest rate applied.

Each section focuses on calculating a different variable and questions are carefully sequenced so that only one given variable changes each time. The last question in each section involves learners working with two differing percentage rates with the same investment.

Calculators are required and students should be encouraged to solve problems by forming and solving equations rather than using trial and error.
