What is the savings goal calculator?

In short

To find how long it takes to reach a savings goal, divide the gap between your goal and current savings by your monthly contribution, then adjust for interest earned along the way. KalkWise simulates month by month: it tells you the exact date you reach the goal, or how much more you'd need to save each month to hit it on time.

This savings goal calculator works backward from a target. Enter a goal amount and your plan, and it tells you whether and when you'll reach it — or how much more to save each month to get there by your deadline.

How to use this calculator

  1. 1Enter your savings goal and current savings.
  2. 2Add your planned monthly contribution and interest rate.
  3. 3Set the time frame you're aiming for.
  4. 4See the goal banner: when you'll reach it, or the shortfall.
  5. 5Adjust the contribution to close any gap.

The formula

FV=P(1+rn)nt+PMT×[(1+rn)nt−1rn]
We take the growth equation and solve it the other way round — finding the number of periods (or the contribution) that makes your balance reach the goal.
FV
— Your goal (target amount)
P
— Current savings
PMT
— Monthly contribution
r
— Annual rate (decimal)
n
— Compounds per year
t
— Time to reach the goal

Because the equation can't be solved cleanly for t when there are contributions, KalkWise simulates each month until the balance reaches your goal.

Worked example

The scenario

Goal of $20,000, starting with $2,000, saving $500/month at 4.5%.

gives

The result

You reach your goal in about 2 years and 11 months, earning roughly $700 in interest along the way.

Common use cases

  • Building an emergency fund
  • Saving for a house down payment
  • Planning for a wedding, car, or vacation
  • Setting a realistic monthly savings target

Limitations & assumptions

  • Assumes consistent contributions and a steady interest rate.
  • Does not factor in irregular income or unexpected expenses.
  • Excludes taxes on interest earned.

Frequently asked questions

A common guideline is 20% of income (the 50/30/20 rule). For a specific goal, work backward: saving $500/month at 4.5% APY reaches $20,000 in about 35 months. At $300/month it takes 58 months — 23 months longer and $400 less in interest earned.
