Result summary
Quick answer
With the sample inputs, this calculator returns $1,140,756.94 projected 401(k) balance at age 65. Projected balance in today's dollars: $543,847.53. Use $1,140,756.94 projected 401(k) balance at age 65 as a hypothetical projection of one account, then compare contributions, modeled growth, inflation-adjusted value, plan rules, fees, taxes, and investment risk.
This projects one entered 401(k) account
The result separates starting balance, fixed employee and employer contributions, and modeled growth. It does not infer employer match terms, enforce changing limits, or project the rest of a retirement portfolio.

How to use this calculator
Open the short walkthrough for choosing and checking inputs.
The calculator combines the entered fixed monthly employee and employer amounts, projects them with the current balance to the selected age, and separately discounts the result by the entered inflation rate.

Calculation details
Formula and methodology
See the exact math used to produce the result.
Projected 401(k) balance = current account balance grown monthly plus each fixed employee and employer monthly contribution grown from its selected contribution timing.
Before acting
Assumptions to check
Review the real-world details that can change the estimate.
The key inputs are Current age, Projection age, Current 401(k) balance, Monthly employee contribution, Monthly employer contribution, employer contributions, inflation, and contribution timing. Contributions remain fixed in nominal dollars; the model does not infer a match or enforce changing plan or legal limits, vesting, fees, taxes, or withdrawals.

When to round up
Money rounds to cents after the full projection. Employee and employer contributions remain flat in nominal dollars, and the model excludes changing salary, plan limits, catch-up rules, fees, loans, withdrawals, taxes, vesting, and market volatility.
When to use this calculator
- Projecting one 401(k) account from entered employee and employer contributions
- Separating contributed dollars from modeled growth
- Comparing nominal future value with inflation-adjusted value
Tips for better estimates
- Use the current balance and contribution election from account and payroll records.
- Enter employer contributions separately from the match formula.
- Check plan limits, vesting, fees, taxes, and investment risk outside the projection.
How this calculator is reviewed
This page is checked for inputs, formulas, examples, assumptions, topic fit, and related links. For this calculator, the review also covers current and retirement ages, current account balance, employee and employer contributions, return, inflation, timing, plan limits, vesting, fees, taxes, and uncertain returns.

Sources to verify assumptions
Use these official and consumer-reference sources to check the terms and rules behind the inputs. The calculator result still depends on the values and method you select.
Worked example
Example inputs: Current age: 35; Projection age: 65; Current 401(k) balance: $50000; Monthly employee contribution: $500 /month; Monthly employer contribution: $150 /month; Assumed annual return: 7 %; Assumed annual inflation: 2.5 %; Contribution timing: End of each month. With those values, the calculator returns $1,140,756.94 projected 401(k) balance at age 65. The entered balance and fixed monthly employee and employer contributions project to $1,140,756.94 under one constant-return scenario. Confirm contribution limits, plan rules, fees, vesting, taxes, and the actual employer contribution separately.
Example scenarios
- Use $1,140,756.94 projected 401(k) balance at age 65 as an account-only projection, then compare employee contributions, employer contributions, and modeled growth.
- Enter the employer contribution from a verified plan estimate instead of assuming a standard match formula.
- Rerun the account with a lower return and subtract actual fees outside the model before using it in a broader retirement plan.

FAQs
401(k) Calculator questions
Does this calculate my employer match?
No. Enter the employer amount separately. Use the 401(k) Employer Match Calculator to model one simple match formula, then verify the result with the current plan document.
Does the calculator enforce annual IRS contribution limits?
No. Limits can change by year, differ by contribution type and age, and a plan can impose lower limits. Confirm current limits and plan rules before changing contributions.
Are traditional and Roth 401(k) taxes included?
No. The projection does not calculate contribution tax treatment, tax-deferred growth, qualified Roth distributions, withdrawal taxes, required distributions, or penalties.
Do employer contributions belong to me immediately?
Not always. Vesting schedules and forfeiture rules vary by plan. Entered employer contributions are included in the scenario, but the calculator does not determine vested ownership.
