Consider an initial investment of £100 in a savings account with a 4% compound interest rate per year. In the first year, the investment accrues £4 in interest, increasing the total to £104 . The following year, interest is earned on the new total, and this process repeats annually. The formula for annual compound interest is $$ \text{initial amount} \times (1 + \text{annual interest rate}) ^\text{number of years} $$ . For a 4% interest rate, the multiplier is1.04. If interest is compounded more frequently, such as semiannually, the formula adjusts to reflect the number of compounding periods. Compound depreciation mirrors compound interest, except the multiplier is less than one, reflecting a decrease in value over time. Educational progression can include tackling additional numerical concepts, suchas fractions and rounding. Comprehensive support for understanding these and other GCSE maths concepts is available through structured lessons. For calculations, it's assumed the account remains untouched post-initial deposit. Answers should be rounded to the nearest pound. For further clarification, revision notes on compound interest can beconsulted.

FAQs

What is compound interest and how does it differ from simple interest?

Compound interest earns interest on the initial investment and on the accumulated interest from prior periods, so the total grows faster over time than simple interest.

What formula is used for annual compound interest?

Annual compound interest is calculated with: initial amount × (1 + annual interest rate)^number of years.

How should answers be handled in the worksheet calculations?

Calculations assume the account is not touched after the initial deposit, and answers should be rounded to the nearest pound.
