How the projection works

Each year your contribution (capped at the 2026 limit for your age) and the employer match are added, and the balance grows at the chosen return. Salary rises by the chosen percentage each year. Traditional 401(k) contributions also lower your taxable income today: see the effect in the paycheck calculator.

Frequently asked questions

What is the 401(k) limit for 2026?

You can defer up to $24,500 in 2026. Workers aged 50 and over can add an $8,000 catch-up ($32,500 in total), and those aged 60 to 63 an $11,250 catch-up ($35,750 in total), per IRS Notice 2025-67.

How much will my 401(k) be worth?

Saving 8% of a $75,000 salary with a 50% match up to 6%, a $25,000 balance, 6% returns and 2% raises grows to about $954,589 by age 65.

Should I contribute enough to get the full match?

Yes, in almost every case: an employer match is an immediate return on your contribution, often 50% or 100%, before any investment growth.
