Retirement Calculator for a 40 Year Old
At 40 you're in your peak earning years with roughly 27 years until full retirement. That's still enough time for compounding to do the heavy lifting. The move now is to lock in a strong savings rate before the window narrows.

Where you should be at 40
Fidelity recommends having 3 times your annual salary saved by age 40. On a $75,000 income, that puts the target at $225,000. On $100,000, it's $300,000. The next milestone, 6 times salary, lands at 50.
Real balances run lower. The average 401(k) for the 35 to 44 age group is $103,552, and the median is closer to $38,000 (Vanguard, How America Saves 2025). Half of all 40 year olds with a 401(k) have less than $38,000 in it. If that's you, the gap is closable, but it takes a deliberate increase in your savings rate, not just time.
The advantage at 40 is that compounding still has decades to run. A dollar invested now can grow more than fivefold by 67 at a 7% return, which is why raising your rate today beats waiting until the catch-up years.

Retirement strategies at 40
Push your savings rate to 15% or more
The single biggest lever at 40 is the percentage of income you save, including any employer match. Someone starting in earnest at 40 generally needs 15% to 20% to reach a comfortable target by 67. If you're not there yet, raise the rate by one or two points each year until you are. The increases are easier to absorb gradually than all at once.
Capture the full employer match
A 401(k) match is an immediate, guaranteed return that nothing else in your plan can match. If your employer offers one and you're not contributing enough to capture all of it, that's the first gap to close, before extra mortgage payments, before a 529, before anything else. Our 401(k) calculator shows what the match adds over 27 years.
Use the HSA as a stealth retirement account
If you have a high-deductible health plan, a health savings account is the only account that's triple tax-advantaged: deductible going in, tax-free growth, and tax-free withdrawals for medical costs. Contribute, invest it rather than spending it, and let it grow. In retirement it covers the healthcare expenses that are otherwise one of the largest line items.
Don't let lifestyle creep eat your raises
The 40s are when income often rises fastest and so does spending. The habit that builds wealth is directing a share of every raise to savings before it reaches your lifestyle. Automating a contribution increase to coincide with each raise is the simplest way to make it painless and permanent.
Keep your money invested for growth
With nearly three decades to retirement, a 40 year old generally still wants a growth-oriented, stock-heavy allocation. The biggest risk at this age isn't market volatility, which you have time to ride out, but being too conservative and missing the compounding you're counting on. Our inflation calculator shows why outpacing inflation over 27 years matters so much.
