How to Automate the Service Contract Act Health and Welfare Calculation

"How can I automate the SCA health and welfare calculation for our service contract employees? We do it in a spreadsheet now and pay the excess as cash in lieu every payroll. Is there software for this?"

That is close to word for word how contractors ask it. Behind the question there is usually one workbook: hours keyed in from the ERP, VLOOKUPs against the carrier statements, a column that flags who came up short, and a cash-in-lieu line handed to payroll each pay period.

The short answer is yes, there is software for the Service Contract Act (SCA) Health & Welfare calculation. Whether you need it depends on which of three models you run.

What "Automate" Means on This Page

Two different things get called automation, and it helps to separate them before any product is named.

The first is the calculation: hours against the Wage Determination rate, benefits credited per employee with effective dates, the shortfall, the payout, and the record of all of it.

The second is the plumbing: the hours file arriving from payroll on its own, the carrier invoice arriving from the benefits platform on its own, and the cash-in-lieu or 401(k) file going back without anyone touching it.

This page is about the first. SimpleFringe automates the calculation and the record; the plumbing, today, is a file you upload and a file you export.

What the SCA Health and Welfare Calculation Actually Is

For each employee, each period: hours paid, up to 40 per week, times the H&W rate in the Wage Determination incorporated in that employee's contract, minus the employer-paid benefits credited for the period. What is left is the shortfall, and it is paid as cash or as a retirement plan contribution.

That is one line of arithmetic. It goes wrong by hand in three places.

1. A rate change. A new H&W rate reaches your contract when the Contracting Officer issues a modification incorporating the revised Wage Determination, which is often not on the anniversary date. SimpleFringe tracks each Wage Determination with a link to its source on SAM.gov and sends rate-change alerts. The alert tells you a new rate exists. The modification is what puts it on your contract.
2. Benefit changes with effective dates. Open enrollment, a marriage, a new baby. The employer-paid credit changes on a specific date, and a missed date makes every later period wrong.
3. Termination payouts. A departing employee's shortfall is part of final pay, and some states want final pay the same day.

The long version of how each of these breaks a workbook is in Why Spreadsheets Fail at SCA Compliance, and the arithmetic itself is in how to calculate SCA Health & Welfare.

The Honest Answer Depends on Which Model You Run

Your H&W obligation is a dollar figure, and there is more than one compliant way to meet it. There are three ways to run it, and only one of them needs calculation software. The full side-by-side table is on our software vs. trust or TPA comparison page.

Run it in-house on a spreadsheet

Best fit: one benefits package for everyone, or all-cash fringe, at low headcount. If that is you, the spreadsheet is enough, and a payroll earnings code may be all the automation you need. Excel is free until an error costs you back pay, and with one package or all cash there are few places for an error to hide.

Hand it to a provider

There are two kinds. An insurance-bundled TPA packages benefits and compliance through the provider's group or multi-employer trust, and you usually adopt their plan design. An employer-sponsored H&W trust is one you fund yourself: irrevocable, tax-exempt, often with a reserve account for each employee. The dollars are committed once deposited, and a third party holds them.

Both are legitimate. If you have a provider and it is working, keep it, and you do not need this page. The per-employee statement comes from them. SimpleFringe does not replace a TPA, is not a benefit plan, and sells no insurance.

Run it in-house on software

This is the hybrid fringe model: a benefits menu, the employer-paid portion credited per employee, and each shortfall trued up as cash-in-lieu or a retirement contribution. It is the hardest model to administer, because per-employee variances, proration across contracts, and mid-cycle life events all land at once. Contractors stay in-house anyway because they want control of their fringe dollars and their benefit design.

This is where "is there software for this" gets a yes. Within this model, the calculation can live in three places:

• A GovCon ERP you already run. The rate times hours side can be configured. Per-employee benefit crediting with effective dates is usually the part that ends up in a side workbook. Treat it as a configuration project, not a product.
• A payroll provider's earnings code. This handles the payout line on the check. The credit side, which decides how much the payout should be, still lives somewhere else.
• Purpose-built calculation software. This is SimpleFringe. It is software, not a plan. It calculates the obligation per employee and per contract, credits the employer-paid benefits each person chose, finds each shortfall, and keeps the record.

A trust holds your fringe. SimpleFringe leaves it with you and just proves the math.

What "Automated" Has to Mean: Questions to Ask Any Vendor

Ask these of any vendor, including us.

• Is the calculation per employee, or an average? Under an odd-numbered Wage Determination, each employee must receive the full rate.
• Does it apply the 40-hour weekly cap? Hours paid beyond 40 in a week carry no H&W obligation.
• Are benefit changes effective-dated? A change in March should not rewrite January.
• Are Wage Determination revisions tied to the modification date? The rate that binds you is the one your Contracting Officer incorporated, not the newest one DOL published.
• Can it run a termination payout off-cycle? Final pay does not wait for the next reconciliation.
• Does it support any payout method? Cash, a retirement contribution, or a mix, because a prime contractor can forbid cash in lieu on a contract.
• Can a DOL investigator follow the record? What was calculated, when, at what rate, and how each shortfall was paid.
• How does data get in and out? Our answer: CSV import from your payroll and benefits exports, mapped once to your column names, and CSV export in the layout your payroll and retirement provider accept. There are no live integrations with payroll providers, ERPs, or carriers today. If you need one, tell us, and we will tell you whether it is buildable with your vendors.

Bid Side and Payroll Side Are Different Calculations

The fringe rate you bid and the credit you track after award are two separate pieces of math. The bid side asks what your SCA fringe costs as a rate when you price the contract. The payroll side asks what each employee is owed this period.

For the bid side, Jenny Clark, GovCon CFO at Solvability, publishes a free SCA Fringe Rate Calculator on GitHub. We walked through it together in this conversation. Everything else on this page is the payroll side.

Where SimpleFringe Fits

SimpleFringe is for the contractor on the hybrid model whose process owner runs H&W in-house, at any headcount. It replaces the workbook and keeps the proof: the per-employee calculation, the shortfall, how it was paid, and a point-in-time record of each period.

Data comes in as a CSV you upload from your payroll and benefits exports, and goes out as a CSV your provider accepts. If that is the workbook you are maintaining, book a demo and I will walk you through it on your own numbers.

Frequently Asked Questions

Is there software to calculate SCA health and welfare?

Yes. A GovCon ERP can be configured for the rate times hours side, and SimpleFringe is purpose-built software for the full per-employee calculation: obligation, benefit credit, shortfall, payout, and record.

Can my payroll provider calculate SCA H&W?

A payroll provider can pay an H&W amount through an earnings code. What usually sits outside payroll is the per-employee credit for employer-paid benefits, with effective dates, which is what determines the shortfall. Ask your provider what it can set up for your account.

Does SimpleFringe connect to my payroll system?

There is no live integration today. You upload the payroll and benefits exports you already produce, mapped once, and you download a payout file in your provider's layout.

Can I keep using Excel for SCA compliance?

Yes, if you pay all-cash fringe or run one benefits package for everyone at low headcount. Excel gets risky when each employee has different benefits, effective dates, and contracts.

What is the current SCA health and welfare rate?

$5.92 per hour standard, and $5.42 per hour on contracts subject to EO 13706, per AAM 252, dated August 7, 2026, for bids opened and contracts awarded on or after August 10, 2026. The rate reaches an existing contract when the Contracting Officer issues a modification incorporating the revised Wage Determination.

Does a prime contractor have to allow cash in lieu?

No. A prime contractor or an agency can require that shortfalls on a contract go to a retirement plan instead of cash. The obligation is calculated the same way either way; only the payout method changes.

Who at a contractor usually owns this calculation?

Finance or operations at small and mid-size firms. HR benefits usually takes it over once there is a TPA.
