Average Benefit Percentage Test Calculator
If you manage or administer a company retirement plan—such as a 401(k)—you must ensure it complies with IRS nondiscrimination rules. One key requirement is the Average Benefit Percentage (ABP) Test, part of the broader Average Benefits Test used to ensure fair treatment across all employee levels.
The Average Benefit Percentage Test Calculator is a fast and reliable tool that helps you determine whether your retirement plan passes this compliance requirement. By comparing the average benefit received by non-highly compensated employees (NHCEs) to that of highly compensated employees (HCEs), this test protects against plans that disproportionately favor executives or key personnel.
Whether you’re an HR manager, benefits administrator, payroll provider, or third-party administrator (TPA), this calculator makes complex plan testing simple and transparent.
Formula
The test compares the average benefit percentages of two employee groups:
Average Benefit Percentage Test Ratio = (Average Benefit % for NHCEs ÷ Average Benefit % for HCEs) × 100
To pass, the plan must meet at least one of the following thresholds:
- 70% Test: The NHCE average must be at least 70% of the HCE average.
- Nondiscriminatory Classification Test + ABP Test: If the classification test is passed, a lower ratio may be permitted, subject to IRS rules.
How to Use
Using the Average Benefit Percentage Test Calculator is easy:
- Enter the Average Benefit % for NHCEs – This is typically based on plan benefits such as employer contributions or defined benefits accrued.
- Enter the Average Benefit % for HCEs – Use the same methodology as for NHCEs.
- Click “Calculate” – The result will show the ABP ratio and whether your plan passes.
- Interpret the Result:
- A ratio ≥ 70% means the plan passes the ABP Test.
- A ratio < 70% may still pass with additional testing, but may indicate potential compliance risk.
Example
Example 1: Pass Scenario
- NHCE Average Benefit % = 4.2%
- HCE Average Benefit % = 5.5%
ABP Ratio = (4.2 ÷ 5.5) × 100 = 76.36%
✅ Result: Pass
Example 2: Fail Scenario
- NHCE Benefit = 2.8%
- HCE Benefit = 5.0%
ABP Ratio = (2.8 ÷ 5.0) × 100 = 56.00%
❌ Result: Fail
In the second case, the employer may need to adjust contributions, perform additional tests, or amend the plan design.
FAQs
1. What is the Average Benefit Percentage Test?
It’s a nondiscrimination test used to ensure qualified retirement plans don’t disproportionately benefit highly compensated employees.
2. Who is considered a Highly Compensated Employee (HCE)?
Generally, anyone earning more than a set IRS threshold (e.g., $150,000 in 2023) or owning more than 5% of the business.
3. Who is a Non-Highly Compensated Employee (NHCE)?
Employees who don’t meet the HCE definition.
4. What is considered a benefit for this test?
Employer contributions, accrued pension benefits, or other qualified retirement plan benefits.
5. What is the 70% threshold?
To pass the test outright, the NHCE average must be at least 70% of the HCE average.
6. What if my plan fails the 70% test?
You may still pass the test if you also pass the Nondiscriminatory Classification Test and a safe harbor adjustment.
7. How do I calculate benefit percentages?
Divide the benefit amount by each employee’s compensation, then average across the group.
8. Is this test required annually?
Yes. It must be performed each year the plan is in operation.
9. Does this apply to all retirement plans?
It applies to most qualified plans, including 401(k), profit-sharing, and defined benefit plans.
10. What’s the difference between this and the ACP/ADP tests?
ADP/ACP tests focus on employee and matching contributions; the ABP Test focuses on employer-provided benefits.
11. Can Safe Harbor plans skip this test?
Some Safe Harbor plans are exempt from ADP/ACP tests but may still need to run the ABP Test in certain scenarios.
12. Who performs this test?
Typically, your plan administrator, payroll provider, or TPA.
13. Can test results vary by contribution formula?
Yes. Different contribution structures (e.g., tiered vs flat-rate) affect the average benefit %.
14. What’s the consequence of failure?
You may need to revise contributions, refund excess amounts, or amend the plan—possibly facing IRS penalties if uncorrected.
15. Is this calculator IRS-compliant?
It’s a helpful tool, but final compliance should be confirmed through formal nondiscrimination testing by professionals.
16. Does employee age affect this test?
Yes, especially in defined benefit plans where accruals are age-weighted.
17. Are leased employees included?
They may be, depending on plan participation and eligibility.
18. How accurate is this calculator?
It’s mathematically accurate based on user input but doesn’t replace a full nondiscrimination analysis.
19. What if the ratio is exactly 70%?
Your plan passes. Anything 70.00% or higher is considered compliant.
20. Where can I find official IRS guidance?
IRS Publication 560 and the Internal Revenue Code Sections 401(a)(4) and 410(b) contain detailed rules.
