The sooner you start to save, the more you'll earn with compound interest. Show
How compound interest worksCompound interest is the interest you get on:
For example, if you have a savings account, you'll earn interest on your initial savings and on the interest you've already earned. You get interest on your interest. This is different to simple interest. Simple interest is paid only on the principal at the end of the period. A term deposit usually earns simple interest. Save more with compound interestThe power of compounding helps you to save more money. The longer you save, the more interest you earn. So start as soon as you can and save regularly. You'll earn a lot more than if you try to catch up later. For example, if you put $10,000 into a savings account with 3% interest compounded monthly:
Compound interest formulaTo calculate compound interest, use the formula: A = P x (1 + r)n A = ending balance How to calculate compound interestTo calculate how much $2,000 will earn over two years at an interest rate of 5% per year, compounded monthly: 1. Divide the annual interest rate of 5% by 12 (as interest compounds monthly) = 0.0042 2. Calculate the number of time periods (n) in months you'll be earning interest for (2 years x 12 months per year) = 24 3. Use the compound interest formula A = $2,000 x (1+ 0.0042)24  Lorenzo and Sophia compare the compounding effect Lorenzo and Sophia both decide to invest $10,000 at a 5% interest rate for five years. Sophia earns interest monthly, and Lorenzo earns interest at the end of the five-year term. After five years:
Sophia and Lorenzo both started with the same amount. But Sophia gets $334 more interest than Lorenzo because of the compounding effect. Because Sophia is paid interest each month, the following month she earns interest on interest.

Time = 2 years Formula used: A = P(1 + R/100)T Where, A = Amount, P = Sum or Principal R = Rate of interest T = Time Calculation: Let the Principal be 100 Then Amount becomes 144 Now, A = P(1 + R/100)T ⇒ 144 = 100 × (1 + R/100)2 ⇒ (144/100) = (1 + R/100)2 ⇒ (12/10)2 = (1 + R/100)2 Now, 12/10 = 1 + (R/100) ⇒ 2/10 = R/100 ⇒ R = 20% ∴ The rate of interest is 20%.
