You can use the Savings Calculator to figure out how much money you'll save over a certain number of years. To use this calculator, provide the following information:
1. The initial amount you'll put into your account (it might be anything)
2. The amount you'll put aside every week, fortnight, or month
3. The interest rate you'll be able to earn
4. The length of time you'll put your money to work.
After that, you'll be told how much money you'll have in total at the end of the savings term, as well as a breakdown of how much of it is interest vs money you've invested.
