What if analysis for indirect rates is a way to test a business decision against your cost structure before you make it. You change the dollars in one or more cost pools to reflect a new hire, a lease, a wage increase, or an equipment purchase. You then see how your fringe, overhead, and G&A rates respond. It answers a question every government contractor faces sooner or later: what will this decision do to my rates?

Without it, the effect on your rates often stays unclear until the money has been committed. By then the decision has already been made, and the rates simply report the result.

How Does a Change in One Pool Affect Your Other Indirect Rates?

A change in one pool moves the others, and the effects do not always point the same way. An increase in fringe flows into the overhead and G&A pools and typically raises both rates. An increase in overhead can lower the G&A rate. Those overhead dollars enlarge the base that G&A is spread across, while the G&A pool itself has not changed. The direction depends on how your G&A base is built.

Quantifying these interactions by hand is slow and invites error, especially when several pools move at once. The same cascade explains why intra pool and inter pool adjustments carry different risk. We covered that in modeling a rate change before you make it. An accurate answer needs a tool that recalculates the whole structure every time.

How Does What-If Analysis for Indirect Rates Work in Rate Studio?

Rate Studio starts from your baseline budget. You can increase or decrease dollars by cost element within any pool, such as labor, materials, or subcontractors. You can also model renting a new facility, hiring employees, adjusting wages, or buying or leasing equipment. The indirect rate structure stays the same, so the analysis isolates the dollar change and shows how each rate responds.

Results are instant, so you can run several scenarios and compare them. For example, you might test hiring two people in the first quarter against hiring them mid-year, or compare leasing a piece of equipment with buying it. Each scenario helps you find the right balance when the decision is difficult.

When Should You Run a What-If Analysis for Indirect Rates?

Run one before any decision that meaningfully changes your costs or your revenue base. A common trigger is a proposal for a large contract that would significantly increase revenue. I use a 20% threshold. Many businesses can absorb a 20% revenue increase without adding expenses. Beyond that point, you likely need additional staff, equipment, supplies, or other resources, and each one changes your cost pools.

The same analysis applies when circumstances shift in the other direction. Award schedules move, contracts are canceled, and proposed work goes to another bidder. Each event changes your revenue forecast and the base your costs are spread across. Staff hired ahead of backlog, as described in what growth does to your indirect rates, leaves your rates exposed. The expected work may arrive late or not at all.

Significant budget items outside your original plan also deserve a scenario before you commit. New hires, equipment, and software all land in your pools, and seeing the rate impact first lets you decide whether the timing and amount make sense.

Which Organization Should Your Proposal Rates Reflect?

Your proposal rates should reflect the organization you will be when you win the award. That organization can look very different from what it is today. A $5M company proposing a $3M contract will be an $8M company while it performs the work. The proposal adequacy checklist in DFARS 215.403-5 asks contractors to identify changes in business volume and planned changes in indirect costs. This analysis helps you answer a question reviewers are already asking.

What Do You Do With the Results of a What-If Analysis?

The results are pro forma rates, and they belong in your proposals because they represent the organization you will be when the work begins. They also belong in your rate management during the year.

When any of these events means actual rates will come in higher or lower than budgeted rates, consider updating your proposal and billing rates to match. Contractors can change billing rates during the year, usually on a contract-by-contract basis. They can also ask DCAA for a blanket update in the form of an updated provisional billing rate letter. On cost reimbursement contracts, FAR 52.216-7 allows billing rates to be revised by mutual agreement to prevent substantial overpayment or underpayment. Keeping rates current keeps your pricing competitive and your billing close to reality. As a result, the difference does not surface as a surprise at year-end.

Where Should the Baseline for a What-If Analysis Come From?

Every what-if analysis for indirect rates starts from a baseline, and the baseline is your budget. If you haven’t finished your 2027 budget, our guide to building your indirect rate budget walks you through the process. It draws on the budget section of my book, Government Contract Accounting Made Easy.

Frequently Asked Questions

What is a pro forma indirect rate?

A pro forma indirect rate is a projected rate calculated for the organization you expect to be after a change. Examples include winning a large award or adding a facility. It replaces today’s actual rate in a proposal when your cost structure will look different while the work is performed.

Does a fringe increase change the overhead and G&A rates?

Yes, fringe costs flow into the overhead and G&A pools, so an increase typically raises both rates. The size of the effect depends on how your pools and bases are built, so the full structure needs to be recalculated.

How much revenue growth should trigger a what-if analysis for indirect rates?

I use a 20% threshold. Many businesses can absorb a 20% revenue increase without adding expenses. Beyond that point, you likely need more staff, equipment, supplies, or other resources, and each one changes your cost pools.

Can you change billing rates during the year?

Yes, usually on a contract-by-contract basis. You can also ask DCAA for a blanket update in the form of an updated provisional billing rate letter. FAR 52.216-7 allows revisions by mutual agreement to prevent substantial overpayment or underpayment.

Does what-if analysis for indirect rates replace my accounting system?

No. Your accounting system records actuals and calculates actual rates from live data. What-if analysis models the future from those actuals, so the two work together.
