Salary Negotiation: Before accepting any offer or raise, see our complete Salary Negotiation Guide for scripts, timing strategy, and non-cash alternatives.

If you forgot to enroll in your 401(k), contact HR today — you may be able to sign up immediately. Every pay period without enrollment is lost employer matching contributions you can never get back.

What to Do Right Now

Step Action
1 Log into your benefits portal or contact HR
2 Check if enrollment is open now
3 Enroll and set your contribution rate (at least enough to get full match)
4 Choose your investments (target-date fund if unsure)
5 Check if auto-enrollment already signed you up

The Real Cost of Delayed Enrollment

Years Missed Salary $50,000 Salary $75,000 Salary $100,000
1 year $1,500 match + growth $2,250 match + growth $3,000 match + growth
3 years $4,500+ $6,750+ $9,000+
5 years $7,500+ $11,250+ $15,000+
10 years $15,000+ $22,500+ $30,000+

Based on 50% match on first 6% of salary. Doesn’t include investment returns on the match, which would make the loss significantly larger.

How Much to Contribute

Priority Contribution Level
Minimum: get full employer match Usually 3-6% of salary
Good target 10-15% of salary (including match)
Aggressive catch-up Max out at $23,500 ($31,000 if 50+)

Common Employer Match Formulas

Match Formula Your 6% Contribution ($75K Salary) Free Money
100% match on first 3% $4,500 + $2,250 match $2,250/year
50% match on first 6% $4,500 + $2,250 match $2,250/year
Dollar-for-dollar on first 6% $4,500 + $4,500 match $4,500/year
25% match on first 6% $4,500 + $1,125 match $1,125/year

Investment Options If You’re Not Sure What to Pick

Option Best For Why
Target-date fund matching your retirement year Most people Automatically adjusts allocation as you age
S&P 500 index fund Comfortable with all-stock Lowest fees, broad diversification
Balanced fund (60/40) Moderate risk tolerance Mix of stocks and bonds
Default investment (if auto-enrolled) Not sure Plan’s default is usually a target-date fund

The Bottom Line

Enroll today — even one pay period of missed employer match is money you can never get back. Set your contribution rate to at least capture the full match (usually 3-6% of salary). If you’ve missed years, contribute as aggressively as you can afford. A target-date fund is a perfectly good “set and forget” investment choice if you’re not sure what to pick.
