Estimate your 401k balance at retirement based on your salary, contribution rate, employer match, and expected investment returns
I want to estimate how much my 401k will be worth when I retire so I can plan ahead and make smarter contribution decisions. I am currently [CURRENT_AGE:number:18-70] years old and my annual gross salary is [ANNUAL_SALARY]. My current 401k balance is [CURRENT_BALANCE]. I contribute [CONTRIBUTION_RATE:number:1-100] percent of my salary to my 401k each pay period. My employer match is [EMPLOYER_MATCH:select:no employer match,25% up to 6% of salary,50% up to 6% of salary,100% up to 3% of salary,100% up to 4% of salary,100% up to 6% of salary,dollar-for-dollar up to a fixed amount,other custom match]. My account type is [ACCOUNT_TYPE:select:traditional pre-tax 401k,Roth 401k after-tax,both traditional and Roth]. I plan to retire at age [RETIREMENT_AGE:select:55,59.5,60,62,65,67,70]. I expect my salary to grow by roughly [SALARY_GROWTH:select:1% per year,2% per year,3% per year,4% per year,not sure use 3%] on average. For investment returns I expect [EXPECTED_RETURN:select:conservative 5%,moderate 7%,aggressive 9%,not sure use 7%]. I am [CATCH_UP_ELIGIBLE?] regarding catch-up contributions (mention if you are 50 or older or will be during the projection period). Calculate my projected 401k balance at retirement year by year, showing total contributions, employer match contributions, and investment growth separately. Include the annual contribution limit for the current year and flag whether my contribution rate exceeds it. Show how much of my final balance comes from my own contributions versus employer match versus compound growth. Provide three scenarios: one with my current inputs, one where I increase my contribution by 2 percentage points, and one where I max out the annual limit. If I selected both traditional and Roth, compare the after-tax value of each assuming a reasonable tax bracket. Finish with specific recommendations on whether I should adjust my contribution rate, and explain any catch-up contribution options if I am approaching 50 or older.
Range: 18 - 70

Get Early AccessPlanning for retirement is easier when you can see the numbers clearly. A 401k calculator takes your current age, salary, contribution rate, and employer match, then projects your account balance year by year until retirement. The most useful part is the breakdown: how much comes from your own paycheck, how much your employer adds for free, and how much compound growth generates on top of both. That three-way split often surprises people, because investment returns typically account for more than half the final balance over a 20- to 30-year horizon.
This 401k calculator prompt lets you enter your [CURRENT_AGE], [ANNUAL_SALARY], and [CONTRIBUTION_RATE] to generate a full projection with three comparison scenarios. You will see your current trajectory alongside what happens if you bump contributions by two percentage points or max out the annual limit. Open it in the Dock Editor to run the calculation in seconds and get personalized recommendations.
Combine your 401k projection with the budget builder to confirm your increased contributions fit your monthly cash flow. For a complete savings picture beyond your 401k, use the emergency fund calculator to confirm your rainy-day reserve is on track, or the college savings calculator to plan education funding alongside retirement.
Provide your [CURRENT_AGE], [ANNUAL_SALARY], and [CURRENT_BALANCE]. These three inputs anchor the entire projection and determine how many compounding years remain before retirement.
Enter your [CONTRIBUTION_RATE] as a percentage of salary and select your [EMPLOYER_MATCH] structure. The calculator flags whether your rate captures the full employer match so you do not leave free money on the table.
Select your target [RETIREMENT_AGE] and pick an [EXPECTED_RETURN] and [SALARY_GROWTH] rate. If you are unsure, the default moderate options (7% return, 3% salary growth) reflect long-term historical averages for a diversified portfolio.
Select [ACCOUNT_TYPE] to indicate whether you contribute to a traditional pre-tax 401k, a Roth 401k, or both. If you choose both, the output includes an after-tax comparison to help you decide where to direct future contributions.
Compare the three output scenarios: current rate, current rate plus two percentage points, and maximum annual contribution. Use the side-by-side numbers to pick the contribution level that balances retirement growth with your monthly budget.
See how starting 401k contributions in your 20s or 30s multiplies your balance through decades of compound growth. Compare a modest 3% contribution against a 6% rate to understand why increasing early has the biggest long-term impact.
Check whether your current savings rate puts you on track for your target retirement age. Use the three scenarios to find the contribution bump that closes any gap without straining your monthly budget.
Model the effect of catch-up contributions once you become eligible. See how the extra allowance above the standard annual limit accelerates your balance during the final 15 to 20 working years.
Plug in different employer match structures from competing job offers to see which package produces the largest 401k balance over time, turning a vague benefit into a concrete dollar figure for salary negotiations.
