Show the math

Your balance grows, then contributions close the remaining gap:

PMT = (goal − P(1 + i)n) / (((1 + i)n − 1) / i)

Your current savings compound at the rate, and the tool solves for the level monthly amount whose growth fills the rest by the target date. If your balance alone will reach the goal, the required contribution is zero. Your current savings, total contributions, and interest add up to the goal.

What this does

A savings goal calculator finds the monthly amount you need to set aside to hit a target by a set date, accounting for your current balance and the interest it earns along the way.

How to use it

  1. Enter your savings goal and target date.
  2. Enter your current balance.
  3. Enter the interest rate you expect to earn.
  4. Read the monthly contribution required.

How it works

The tool grows your current balance at the expected rate, then solves for the level monthly contribution whose compounded future value closes the remaining gap to your goal by the target date.

Understanding your result

A higher rate means your balance does more of the work, lowering the monthly amount you need. If your current savings already grow to meet the goal, the required contribution shows as zero.

Example

To reach $20,000 in 4 years starting from $2,000 at 4% interest, you would need to save roughly $360 a month.
