Retirement Calculator

By · Updated

Project your retirement savings based on your current age, how much you've already saved, what you're adding monthly, and an assumed rate of return. This is a planning estimate, not a promise — actual markets fluctuate.

How the projection works

This uses the same future-value-with-contributions model as compound growth: your current balance keeps compounding for every year until retirement, and each monthly contribution also grows from the month it's added.

FV = P(1 + r)ⁿ + PMT × [((1 + r)ⁿ − 1) ÷ r]
Example

Age 30 with $20,000 saved, adding $500/month, assuming 7% annual return until age 65 (35 years): projected nest egg ≈ $1,130,650, versus $230,000 actually contributed.

Step-by-step guide

  1. Enter your current age and target retirement age.
  2. Enter what you've already saved for retirement across all accounts.
  3. Enter your monthly contribution — include any amount automatically deducted from your paycheck.
  4. Enter an expected annual return and review the projection. Try a lower and higher rate to see a realistic range.

Common mistakes

Leaving out employer 401(k) matching — if your employer matches contributions, add that matched amount into your monthly contribution figure to see the full picture.
Not adjusting for inflation — $1,130,650 in 35 years won't have the same purchasing power as that amount today.

Frequently asked questions

Does this include Social Security or a pension?

No — this only projects your personal savings and contributions. Social Security, pensions, or other guaranteed income sources would be on top of this number.

How do I include employer matching?

Add the employer match amount to your own monthly contribution figure — for example, if you contribute $400 and your employer matches $200, enter $600 total.

What return rate is realistic for retirement accounts?

It depends heavily on your mix of stocks and bonds and changes as you get closer to retirement (many people shift to more conservative investments over time). There's no universally "correct" number — this calculator is a planning estimate, not financial advice.
