Mastering the Math Behind Your Employee Retention Credit Refund
What You Need to Know About Calculating Employee Retention Credit
Calculating employee retention credit amounts comes down to a few key variables: your eligibility period, your credit rate, your wage cap, and your employee count in 2019. Here’s the short version:
| Year | Credit Rate | Wage Cap (Per Employee) | Max Credit |
|---|---|---|---|
| 2020 | 50% | $10,000 (annual) | $5,000 per employee |
| 2021 (Q1-Q3) | 70% | $10,000 (per quarter) | $7,000 per employee per quarter |
| 2021 Total | – | – | Up to $21,000 per employee |
| Both Years Combined | – | – | Up to $26,000 per employee |
These numbers can add up fast. A business with just 10 employees could be looking at $260,000 in refundable payroll tax credits.
The ERC is a refundable payroll tax credit created under the CARES Act. It was designed to help businesses that kept employees on payroll during the COVID-19 pandemic. Even though the program ended September 30, 2021, you can still claim it retroactively by filing an amended return.
The catch? Getting the math right is harder than it looks. The rules changed significantly between 2020 and 2021. Employee thresholds shifted. Wage caps reset quarterly. And interactions with PPP loans, government grants, and other relief programs add another layer of complexity.

In this guide, I’ll walk you through the exact steps to calculate your credit correctly — so you don’t leave money on the table or expose yourself to audit risk.
Determining Eligibility Before Calculating Employee Retention Credit
Before we start crunching numbers, we have to make sure your business actually qualifies. You can’t build a house on a shaky foundation, and you certainly can’t claim a credit without meeting the IRS’s strict “Eligible Employer” criteria. In our experience helping businesses in Travis County, we’ve seen that eligibility usually falls into two main buckets: the Gross Receipts Test or the Government Mandated Suspension Test.
The Gross Receipts Test
This is a purely mathematical test. You compare your gross receipts from a specific quarter in 2020 or 2021 to the same quarter in 2019 (the “base year”).
- For 2020: You qualify if your gross receipts for a quarter were less than 50% of the gross receipts for the same quarter in 2019. Once you qualify, you stay eligible until the first day of the quarter after your receipts return to more than 80% of that 2019 baseline.
- For 2021: The bar is much lower. You only need a 20% decline in gross receipts compared to the same quarter in 2019.
Full or Partial Suspension of Operations
If your revenue didn’t drop that significantly, you might still qualify if a government order due to COVID-19 fully or partially suspended your operations. This isn’t just about “following guidelines.” It must be a formal order that had a “more than nominal” impact on your business. The IRS defines “nominal” as impacting at least 10% of your total service hours or 10% of your gross receipts in that quarter.
For example, if you own a restaurant in Austin and were forced to close your dining room but kept doing takeout, you were “partially suspended.” If your dining room accounted for more than 10% of your business in 2019, you likely meet the test. You can use this Employee Retention Credit Eligibility Checklist to see where you stand. For a deeper dive, check out our more info about ERC eligibility requirements.
Identifying Qualified Wages and Health Expenses
Once eligibility is established, we need to identify what actually counts as “wages.” It’s not just the number on the paycheck.
- FICA Wages: Generally, these are wages subject to social security tax.
- Qualified Health Plan Expenses: This is a huge “hidden” value. You can include the employer-paid portion of health insurance premiums and even pre-tax employee contributions.
When calculating employee retention credit, many business owners forget to add these health costs back in, which means they’re leaving thousands of dollars on the table. You can find more on the ERC explained for businesses to ensure you’re capturing every cent of qualified expenses.
Impact of 2019 Full-Time Equivalent (FTE) Counts
Size matters when it comes to the ERC. The IRS looks at your average number of full-time employees (those working 30+ hours a week or 130+ hours a month) in 2019 to determine which wages you can claim.
| Feature | 2020 Rules | 2021 Rules |
|---|---|---|
| Small Employer Threshold | 100 or fewer FTEs | 500 or fewer FTEs |
| What Wages Qualify? | All wages paid to all employees | All wages paid to all employees |
| Large Employer Rules | Only wages paid to employees not working | Only wages paid to employees not working |
If you were a “Large Employer” (over 100 FTEs in 2020 or over 500 in 2021), you can only claim the credit for wages paid to employees while they were not providing services. For small employers, every dollar paid during an eligible period counts toward the credit.
Step-by-Step Guide to 2020 ERC Calculations
Calculating the 2020 credit is often the first step for businesses filing retroactively. The 2020 credit applies to wages paid between March 13, 2020, and December 31, 2020.
Step 1: Identify your eligible quarters. Most businesses qualify starting in Q2 of 2020. Step 2: Cap your wages. For 2020, the wage cap is $10,000 per employee for the entire year. Step 3: Apply the percentage. The credit rate is 50%.
The Math Example: Imagine you have an employee named Sam. You paid Sam $8,000 in Q2 and $8,000 in Q3.
- In Q2, you take 50% of $8,000 = $4,000 credit.
- In Q3, Sam has already hit $8,000 of the $10,000 annual cap. Only $2,000 of Sam’s Q3 wages are “qualified.”
- 50% of $2,000 = $1,000 credit.
- Total for Sam in 2020: $5,000.
Even if you paid Sam $50,000 in 2020, the maximum credit you can receive for Sam is $5,000. This is based on the official CARES Act guidance. For more details on these specific rules, see our ERC qualifications guide.
How to Calculate Employee Retention Credit Amounts for 2021
The 2021 rules are where the real “math magic” happens. The government wanted to inject more liquidity into the economy, so they made the credit significantly more generous.
For the first three quarters of 2021:
- The credit rate jumped from 50% to 70%.
- The wage cap changed from $10,000 per year to $10,000 per quarter.
This means you can get a maximum credit of $7,000 per employee, per quarter. Over the first three quarters of 2021, that’s a total of $21,000 per employee.
The Math Example: Let’s look at Sam again in 2021. You pay Sam $10,000 in Q1, Q2, and Q3.
- Q1: $10,000 x 70% = $7,000
- Q2: $10,000 x 70% = $7,000
- Q3: $10,000 x 70% = $7,000
- Total 2021 Credit for Sam: $21,000
When you combine that with the $5,000 from 2020, you’ve reached the famous $26,000 per employee figure. These rules were clarified in IRS Notice 2021-49. We’ve also put together a complete guide to the ERC credit to help you navigate these quarterly resets.
Calculating Employee Retention Credit for Recovery Startup Businesses
There is a special “safety net” for businesses that started during the pandemic. If you began operations after February 15, 2020, and your average annual gross receipts are under $1 million, you might be a “Recovery Startup Business.”
These businesses can claim the ERC for Q3 and Q4 of 2021, even if they didn’t experience a 20% revenue drop or a government shutdown. However, there is a catch: the credit is capped at $50,000 per quarter, for a total maximum of $100,000. It’s a great way for new Austin startups to get a boost. Check the ERC funding requirements to see if your new venture qualifies.
Coordinating ERC with PPP and Other Relief Programs
One of the biggest pitfalls in calculating employee retention credit is “double-dipping.” The IRS is very clear: you cannot use the same dollar of wages to claim both the ERC and PPP loan forgiveness.
If you received a PPP loan, you have to perform a “wage allocation” exercise. We generally recommend using the “PPP-first” approach. You use enough wages to justify your PPP forgiveness, and then any excess wages paid during the eligible period can be used for the ERC.
Other programs also impact your totals:
- Shuttered Venue Operators Grants (SVOG): Wages paid with these grant funds cannot be used for ERC.
- Restaurant Revitalization Grants (RRG): Same rule—no double-dipping.
- FFCRA Credits: If you took credits for paid sick or family leave, those wages are excluded from your ERC calculation.
Getting this coordination right is the difference between a successful refund and a future IRS headache. You can read the IRS guidance on wage coordination or our breakdown on are you eligible for an ERC refund? to make sure your math is airtight.
Frequently Asked Questions about Calculating Employee Retention Credit
What are the deadlines for retroactively claiming the ERC?
Time is running out, but it’s not gone yet. Because the ERC is claimed on an amended payroll tax return (Form 941-X), you generally have three years from the date the original return was filed.
- For 2020 quarters: The deadline is April 15, 2024.
- For 2021 quarters: The deadline is April 15, 2025.
If you haven’t started your ERC credit application path, now is the time to act.
How do I avoid ERC scams and IRS audit risks?
The IRS has issued multiple warnings about “ERC Mills”—promoters who charge huge percentage-based fees (often 15-30%) and promise you qualify without looking at your records.
- The Moratorium: The IRS currently has a moratorium on processing new claims to filter out fraud, though they are still processing the backlog of roughly 400,000 claims.
- Audit Risk: The IRS has extended the statute of limitations to 5 years for ERC audits. If your math is wrong, you’ll have to pay the money back with interest and penalties. Always look for IRS warnings on ERC scams before signing anything.
Can I include part-time employees in my calculation?
Yes! While part-time employees (those working under 30 hours) don’t count toward your FTE “threshold” (the 100 or 500 employee limit), their wages absolutely qualify for the credit. If you have a large staff of part-time workers, your credit could be much larger than you anticipate. Use our ERC eligibility checklist to ensure you aren’t excluding these valuable wages.
