Savings Goal Calculator

Find out when you'll hit a savings target based on your monthly contributions.

How to use

  1. Enter your goal and current savings.
  2. Add your monthly contribution and expected return.
  3. See how long until you reach the goal.

How the Savings Goal Calculator works

Tells you how long a savings target will take given what you have, what you can add each month, and the interest you earn.

It advances the balance one month at a time — applying interest, then adding your contribution — and counts the months until the balance reaches your goal.

while balance < goal: balance = balance × (1 + r) + monthly

Worked example

Saving for a $30,000 deposit with $5,000 saved and $800 a month at 4% takes about 29 months.

Things worth knowing

Frequently asked questions

Does interest matter for short goals?

A little — for short timelines contributions dominate; for long ones compounding makes a big difference.

Is the return guaranteed?

No — it's an estimate using a constant average rate.

Is it better to save more or earn a higher rate?

Over short horizons the contribution dominates by a wide margin. Rate only becomes the bigger lever over ten years and beyond.
