About this calculator

401(k) Growth

A 401(k) calculator projects what your workplace retirement account could be worth at retirement, including the powerful boost from your employer's match. Enter your salary, contribution rate, and expected return to see your balance grow, split by contributions, match, and investment growth.

Don't leave the match on the table

An employer match is the closest thing to free money in personal finance. Many employers match 50% or 100% of what you contribute, up to a percentage of salary, an instant, guaranteed return you can't get anywhere else. If your plan matches up to 6%, contributing at least 6% is almost always the right first move, before any other investing. This calculator splits your projected balance into your contributions, the employer match, and investment growth so you can see how much of the total is match.

Why time is the biggest factor

401(k) balances grow from three things: what you put in, what your employer adds, and decades of compounding on top. Because the earliest dollars have the most years to grow, raising your contribution rate a single percentage point in your 30s can outweigh much larger contributions later. Annual raises help too, bumping your contribution whenever your pay rises is a nearly painless way to save more.

How to use it

  1. Enter your age, current 401(k) balance, and salary.
  2. Set your contribution percentage and your employer's match.
  3. Add an expected return and annual salary growth.
  4. See your projected balance and how much of it is free employer money.

Frequently asked questions

How much will my 401(k) be worth?

It depends on your contributions, employer match, years invested, and return. Enter your details above for a projection broken down by source.

What is an employer 401(k) match?

Many employers match a portion of what you contribute, often 50% or 100% up to a percentage of salary. It's essentially free money and one of the best returns available.

Should I contribute enough to get the full match?

Almost always yes, not capturing the full match leaves guaranteed money on the table. Set your contribution to at least the match threshold.
