Savings Calculator

Project savings growth with deposits and interest toward a goal.

How to use this tool

  • Enter current balance, monthly deposit, rate and years.
  • Or set a goal amount and let the tool solve for the required deposit.
  • Toggle inflation adjustment.
  • View future balance and total contributions.

How it works

Each period the balance grows by deposits and interest: balance = balance × (1+monthly rate) + deposit. Solving for deposit reverses that with the goal as the end state.

Tips

  • Automate the deposit the day after payday.
  • High-yield savings now pay meaningfully more than checking — shop around.
  • Use inflation adjustment for goals more than 3 years out.

Limitations

Assumes constant rate and deposits; penalty-free access assumed.

Frequently asked questions

How much do I need to save monthly for a goal?

The tool solves for the monthly deposit that reaches your target at a given rate within your time frame.

Does it include inflation?

Yes — toggle 'inflation-adjusted target' and it converts your goal to future dollars.

What is the APY?

Annual percentage yield — the effective rate after compounding. Use it if your bank quotes it.
