401(a) Calculator for Government & Nonprofit Workers
Project your 401(a) retirement balance with compound growth. This plan is common for government agencies, public schools, and many nonprofits.
401(a) Inputs
How to Use This 401(a) Calculator
Use this tool when your employer offers a public-sector or nonprofit 401(a) plan and you want to translate fixed employee and employer percentages into a retirement projection.
- Enter age, salary, and current balance. These establish the time horizon and the base on which both contribution percentages are applied.
- Add employee and employer contribution percentages. Unlike a 401(k), many 401(a) plans have employer-defined or mandatory contribution rates.
- Review total contributions versus growth. This helps you see whether the plan's power comes mostly from employer funding or long-term compounding.
How to Read the Results
Retirement Balance
The total projected value at retirement under the current contribution and return assumptions.
Your Total
The cumulative dollars contributed from your own paycheck over the projection period.
Employer Total
The employer-funded side is often the defining feature of a 401(a) plan.
Growth
This shows how much of the final balance came from investment returns rather than raw contributions.
What to Do Next
How We Reviewed This Tool
Tool-Level Methodology
- Reviewed the projection around employer-defined contribution structure, since that is the main way 401(a) intent differs from standard 401(k) searches.
- Checked the public-sector comparison table against the site's 457(b) and 401(k) pages so cross-plan guidance stays consistent.
- Used paired-plan behavior as the main QA lens because many 401(a) users also have access to 457(b) or 403(b) savings.
Assumption Review
- Actual 401(a) contribution rules depend heavily on employer design and may be mandatory rather than elective.
- The projection is a planning estimate and does not replicate pension-office enrollment or payroll systems.
- Users with multiple public-sector plans should treat this page as one piece of the full savings stack.
Update Log
- Reconfirmed 2026 Section 415 cap references shared by 401(a) and 401(k) plans.
- Aligned the page with 457(b) cross-links so public-sector users can explore paired-plan strategies.
- Refined plan-difference wording to better cover government and nonprofit query intent.
What Is a 401(a) Plan?
A 401(a) is an employer-sponsored defined contribution plan authorized under Section 401(a) of the Internal Revenue Code. It is most common at public universities, government agencies, and some nonprofits. Unlike 401(k), the employer typically defines participation, contribution level, and vesting.
401(a) vs 401(k): Key Differences
| Feature | 401(a) | 401(k) |
|---|---|---|
| Who offers it | Government, public schools, nonprofits | Private employers |
| Participation | Often mandatory | Voluntary |
| Contribution structure | Employer-defined (fixed %) | Employee-directed |
| Combined 2026 limit | $70,000 (Section 415) | $70,000 (Section 415) |
| Common with 457(b) | Yes — separate limits | Rarely |
How Much Can You Contribute?
The 2026 combined (employee + employer) cap is $70,000 — same as 401(k). However, because 401(a) often mandates employer-set rates, employees usually cannot voluntarily raise their contribution. Many government workers pair a 401(a) with a 457(b) plan for additional voluntary savings.
Pairing 401(a) + 457(b) = “Double Dipping”
One of the unique benefits of many government jobs: 401(a) and 457(b) have separate contribution limits. An employee can effectively save up to $94,500 per year ($70K 401(a) + $24,500 457(b)). Plus a 403(b) if eligible — a third bucket.
