1
Engagement Mix
10%-45%
Growing analytics work from 10% to 45% shifts revenue toward scalable services and lifts owner income without a full jump in sales effort.
2
Hourly Rate
$160-$240/hr
At $160-$240 an hour, each pricing step up drops straight to take-home if collected rates stay close to billed rates.
3
Payroll Load
$590K-$1.66M
Payroll growth buys more billable capacity, but only if the team stays utilized and partner time stays focused on client work.
4
Contribution Margin
76%-83%
With a 76%-83% contribution margin, small project cost leaks can cut profit fast, while tight delivery keeps more cash for the owner.
5
Overhead Control
$204K
$204K of fixed overhead sets the break-even floor, so rent, insurance, tech, and compliance spend decide how fast profit starts.
6
Cash Runway
$539K
$539K of minimum cash and Month 6 breakeven mean collections and owner draws need to stay tight early on.

How much revenue does an audit firm need to pay the owner?
An Auditing Firm needs about $1.24M in annual revenue to cover its Year 1 fixed stack, because $944K of payroll, overhead, and marketing divided by a 76% contribution margin equals about $1.24M. At the modeled $1.71M of Year 1 revenue, EBITDA comes out near $353K before reserves and taxes. If you want owner pay above the $180K partner salary already inside payroll, add the extra draw and divide by 76%.

What is a good profit margin for an auditing firm?
If you’re asking what a good profit margin looks like for an Auditing Firm, the model points to very high margins: 87% gross margin in Year 1 and 91% in Year 5, with 76% to 83% contribution margin. If you’re sizing launch costs, see What Is The Estimated Cost To Open And Launch An Auditing Firm? so you can judge margin against the upfront spend.

Can a solo audit firm owner make more than a staffed audit firm owner?
Yes, a solo owner can keep more of each collected dollar, but a staffed Auditing Firm can make more total profit once demand pushes past one person’s capacity. In the staffed model, the firm starts with 6 FTEs and about $590K payroll in Year 1, then reaches 17 FTEs and $166M payroll in Year 5, with revenue support rising from about $171M to $1650M. The catch is simple: solo works best when client load and review risk stay small; staffed wins when audit complexity and billable hours need a bigger bench.
Solo owner
Keeps more per collected dollar.
Hits capacity faster.
Review quality gets harder alone.
Best for simpler audits.
Staffed firm
Starts with 6 FTEs.
Year 1 payroll is $590K.
Year 5 reaches 17 FTEs and $166M payroll.
More staff supports more revenue capacity.
Key Takeaways
Higher audit mix lifts revenue if staffing keeps pace.
Write-downs cut contribution before fixed costs get covered.
Utilization must cover payroll, quality control, and training.
Cash timing drives distributions more than accounting profit.

Auditing Firm Core Six Income Drivers
Engagement Volume And Client Mix
Client Mix Drives Audit Capacity
More recurring audit and assurance work can lift owner income because it fills staff time with steadier billing and less sales churn. In the model, financial statement audits rise from 80% to 92%, Sarbanes-Oxley Act internal-control work from 30% to 50%, agreed-upon procedures from 25% to 35%, and data analytics work from 10% to 45%. Engagements run from 15 to 70 hours, so mix changes both revenue and capacity.
Here’s the tradeoff: complex work can support higher fees, but it also increases review time and liability. If staffing does not keep pace, the added work can slow delivery and delay owner pay. Stronger mix supports EBITDA (earnings before interest, taxes, depreciation, and amortization) only when the team can absorb the extra documentation and quality control.
Track Hours, Mix, and Review Load
Measure mix by engagement type, billable hours, and turnaround time. The key inputs are client count, average hours per job, billed rate, rework, and review time. A simple forecast should show how a shift toward more recurring work changes collected revenue, labor cost, and cash timing before the partner draws money.
Track hours by engagement type.
Watch review time per file.
Price complex work for risk.
Limit scope creep fast.
Match staffing to recurring work.
Labor Gross Margin
Labor Gross Margin
Labor gross margin is the spread left after direct delivery costs and variable costs. Here’s the quick math: direct costs fall from 24% of revenue in Year 1 (13% COGS plus 11% variable costs) to 17% in Year 5 (9% plus 8%), so contribution margin improves from 76% to 83%. That cash funds overhead, reserves, and owner pay.
The risk is labor leakage. Overtime, contractor help, rework, and training time can turn a priced engagement into low-margin work even when billings look fine. Payroll is separate and material at $590K to $166M, so the owner’s take-home income depends on keeping delivery hours inside the fee.
Track direct labor by engagement
Measure billed hours, overtime, contractor hours, rework, and training time on every job. Then compare direct labor dollars to fee dollars so you can see which engagements land near the 76% to 83% contribution range and which ones quietly destroy margin.
Fee per engagement
Direct labor hours
Overtime and contractor use
Rework and training time
Use scope control and change orders before work starts, not after overruns hit. If a job needs extra review or outside help, reprice it fast. One clean rule: when direct labor slips, gross profit falls first, and owner distributions follow.
Staff Leverage And Utilization
Staff Leverage And Utilization
Utilization means the share of available staff hours that bill to clients. In this model, trained staff let the owner review more work instead of doing all fieldwork, so the same partner can support more audit volume. That matters because staffing grows from 6 FTEs in Year 1 to 17 FTEs in Year 5, while payroll rises from $590K to $166M.
Owner income improves only when billable hours and realization cover that payroll load. Senior auditors at $110K and junior auditors at $70K can raise output, but audit work has strict quality-control limits. If review time, documentation, and training lag, leverage turns into rework, and the owner keeps paying salary before distributions grow.
Improve Utilization Before Adding Headcount
Track utilization by role, not just firm-wide. Use three inputs: billable hours, review hours, and nonbillable training. If juniors are busy but the partner is buried in review, leverage is fake; cash still gets tied up in payroll before distributions. Here’s the quick math: more hours help only when the work is reviewable, documented, and collectible.
Build staffing plans around engagement mix, then test whether each added FTE lowers owner fieldwork. If onboarding or review standards slip, quality risk rises fast and margin can fall even while revenue grows. Keep one rule: no headcount step-up until training, templates, and review capacity are in place.
Cash Reserves And Owner Distributions
Cash Reserves and Owner Distributions
When audit work is profitable on paper but receivables are still outstanding, the owner can’t safely pull cash. The model shows a $539K minimum cash need at Month 6, with breakeven also in Month 6 and 15 months to pay back launch capex.
This driver depends on billable partner time, collection speed, fixed overhead, and the owner’s draw policy. $350K of launch capex is tied up up front, and slow collections during busy audit periods can delay distributions even when EBITDA looks healthy.
Protect cash before taking draws
Track ending cash, days sales outstanding (DSO, the average days to collect invoices), and work-in-process every month. If collections slip, hold distributions until cash stays above the reserve floor. The clean test is simple: profit does not fund the owner unless cash is actually in the bank.
Watch partner billable hours.
Separate management time from billing time.
Invoice fast after fieldwork ends.
Chase overdue receivables weekly.
Forecast draws only after reserves.
Strong collections turn EBITDA into safer owner pay; weak collections turn the same profit into a cash squeeze. In this model, that squeeze is worst before and around breakeven, when the firm is still absorbing startup capex and audit season timing delays.
Average Fee And Realization Rate
Average Fee and Realization Rate
Average fee is the rate you bill, and realization rate is what you actually collect after write-downs. For this firm, source hourly rates are $180 to $200 for financial statement audits, $220 to $240 for internal-control work, $170 to $190 for agreed-upon procedures, and $160 to $180 for data analytics work.
The inputs are service mix, billable hours, scope changes, and billed-versus-collected revenue. A 10% write-down on 100 hours at $200 per hour cuts revenue by $2,000. That loss hits contribution dollars before fixed costs are covered, so it can delay owner pay even when the schedule is full.
Protect Realized Revenue
Track realization by engagement type, manager, and client. Use a simple formula: realized revenue = billable hours × standard rate × realization rate. If the rate is slipping, the fix is usually scope control, not more volume. One line to watch: fees billed minus fees written down.
Require change orders before extra work starts, review pre-bills before invoices go out, and bill fast on completed work. That keeps cash moving and protects margin. If write-downs keep rising, the firm is giving away time that should fund overhead and owner distributions.
Operating Costs And Compliance Overhead
Fixed Burn and Compliance Load
This driver is the cash drain between billings and owner pay. With $17K per month in fixed overhead, that is $204K a year before any owner draw. The model also includes $8K rent, $15K professional liability insurance, $25K IT and security, $800 compliance fees, and $3K platform maintenance, so overhead can eat cash fast before scale.
Marketing also rises from $150K to $550K, which pushes breakeven higher. If recurring overhead grows faster than billable hours or realization, distributable cash falls even when engagements are profitable. The owner’s income depends on how quickly revenue covers this burn and leaves room for taxes, reserves, and pay.
Track Burn Before Draw
Measure overhead as a share of collected revenue, not just booked work. Track rent, insurance, IT, compliance, platform maintenance, and marketing each month so you can see which cost is fixed and which can flex with volume. Here’s the quick math: $17K per month of fixed overhead must be covered before profit turns into owner cash.
Review overhead every month.
Split fixed and semi-fixed costs.
Approve marketing by payback.
Cut tools that save no hours.
Hold cash for slow collections.
Busy audit periods can look profitable while cash is tight. If overhead stays high before breakeven, the owner may need to keep distributions low until collections, utilization, and realization are stable.
