Formula Used
1. Employee annual contribution:
Employee Contribution = Annual Salary × Employee Contribution %
2. Annual limit adjustment:
Actual Employee Contribution = Lesser of requested contribution and annual elective deferral limit, plus catch-up when eligible.
3. Basic match formula:
Employer Match = Annual Salary × Minimum(Employee %, Match Limit %) × Match Rate
4. Tiered match formula:
Tier 1 Match = Annual Salary × Minimum(Employee %, Tier 1 Limit %) × Tier 1 Rate
Tier 2 Match = Annual Salary × Minimum(Remaining Employee %, Tier 2 Limit %) × Tier 2 Rate
Total Employer Match = Tier 1 Match + Tier 2 Match
5. Vested match:
Vested Employer Match = Employer Match × Vesting %
6. Future projection:
Next Year Balance = Current Balance × (1 + Growth Rate) + Employee Contribution + Employer Match

Frequently Asked Questions
1. What does an employer 401k match mean?
An employer 401k match is money your company adds to your retirement account when you contribute your own pay. The formula often depends on contribution percentage and plan rules.
2. Why does vesting matter in this calculator?
Vesting determines how much of the employer contribution you actually own today. Some plans grant ownership immediately, while others release it gradually over several years.
3. What is the difference between basic and tiered matching?
Basic matching uses one rate and one contribution cap. Tiered matching applies different rates across contribution bands, such as full match on the first portion and partial match afterward.
4. Does this calculator handle annual contribution limits?
Yes. It limits employee deferrals to the annual elective cap you enter, and it can include catch-up contributions when the age field meets the required threshold.
5. Why is my employer match lower than expected?
Your plan may match only up to a certain percentage of salary, not your entire contribution. Vesting limits, annual caps, or lower tier rates can also reduce the value.
6. Can I compare multiple contribution strategies?
Yes. Change the employee contribution percentage or match settings, then recalculate. Reviewing several scenarios helps identify the contribution level that captures the maximum match efficiently.
7. What does the projection graph show?
The graph plots yearly employee savings, employer matching contributions, and projected account balance. It helps you see how matching and compounding work together over time.
8. Is this calculator suitable for official tax or plan advice?
No. It is a planning tool for estimates. Always verify exact plan provisions, tax treatment, annual limits, and vesting schedules with your employer or financial advisor.
