Formula Used

The calculator uses these formulas to calculate savings growth:

Simple Interest: Future Value = Initial Deposit × (1 + (Annual Interest Rate × Time))
Compound Interest: Future Value = Initial Deposit × (1 + Annual Interest Rate)^Time

Where:

  • Initial Deposit - The amount of money you start with
  • Annual Interest Rate - The interest rate per year (in decimal form)
  • Time - The number of years your money will be invested

Note: Compound interest is calculated on the accumulated interest, which means your money grows faster over time compared to simple interest.

Worked Example

Let's say you deposit $1,000 in a savings account with a 5% annual interest rate for 3 years.

Simple Interest Calculation

Future Value = $1,000 × (1 + (0.05 × 3)) = $1,000 × 1.15 = $1,150

Compound Interest Calculation

Future Value = $1,000 × (1 + 0.05)^3 = $1,000 × 1.157625 = $1,157.63

As you can see, compound interest results in a slightly higher amount after the same period.

Tips for Maximizing Savings

To get the most out of your savings account, consider these tips:

  • Start saving as early as possible to take advantage of compound interest.
  • Choose a savings account with a higher interest rate for better returns.
  • Regularly review your savings goals and adjust your contributions accordingly.
  • Consider opening a high-yield savings account for better interest rates.
  • Automate your savings to ensure consistent contributions.

By following these tips, you can maximize your savings and reach your financial goals faster.
