Frequently Asked Questions

Model the 401(k) levers that actually change the outcome

A 401(k) projection is strongest when it separates employee deferrals, employer match, IRS caps, catch-up rules, inflation, and compounding. The IRS lists two separate contribution limits: employee elective deferrals and the overall annual additions limit in its 401(k) contribution guide.

"The match is the obvious win, but the hidden lever is increasing your own contribution rate before salary growth and compounding do the heavy lifting."

Start with the cap

For 2026, the IRS announced a $24,500 employee limit, $8,000 age-50 catch-up, and $11,250 enhanced catch-up for ages 60-63. Adjust the fields if your plan or tax year differs.

Capture the match

The employer match can be modeled as a match percentage up to a salary percentage, with vesting applied before it reaches the final balance.

Compare real dollars

Use the inflation-adjusted line to sanity-check purchasing power. For a second opinion on compounding mechanics, compare with Investor.gov's compound interest calculator.

Planning model, not tax advice

IRS limits, catch-up rules, Roth catch-up rules, employer vesting, plan eligibility, and payroll timing can vary. Confirm final contribution decisions with your plan administrator or tax professional.
