The power of compounding helps you to save more money.MoneySmart
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:
After 5 years, you’d have $11,616. You’d earn $1,616 in interest.
After 10 years you’d have $13,494. You’d earn $3,494 in interest.
After 20 years you’d have $18,208. You’d earn $8,208 in interest.”

Compound interest formula
To calculate compound interest, use the formula:
A = P x (1 + r)n
A = ending balance
P = starting balance (or principal)
r = interest rate per period as a decimal (for example, 2% becomes 0.02)
n = the number of time periods
How to calculate compound interest
To 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
A = $2,000 x 1.106
A = $2,211.64″
