The short answer

An accounting or CPA firm is worth a multiple of its normalized earnings, not its gross fees. In 2026, most lower-middle-market firms sell at 4.0x to 8.0x adjusted EBITDA (around a 6.0x midpoint), while small owner-operated practices still price at roughly 0.75x–1.5x gross recurring fees or 1.8x–3.25x SDE.[2][10][13]

Estimate vs. reality

A calculator estimate is not what a buyer pays

Type your numbers into a free calculator and you get gross fees or earnings times a generic multiple. That is a starting point, not a price. A buyer pays for defensible, normalized earnings — in a CPA firm that starts with the partner-compensation scrape — set against real accounting-sector comps, and that gap routinely moves value 20–50% in either direction.[11][15]

What a free calculator shows you
  • Gross fees or earnings × a single generic accounting multiple
  • One point estimate, no size-band or buyer-pool segmentation
  • No partner-comp scrape, so the earnings input is wrong before the math starts
  • No view of earnouts, rollover equity, APS structure, or net proceeds
What an accounting-firm buyer actually pays for
  • Adjusted EBITDA after the partner-comp scrape, validated in diligence
  • A multiple set by your recurring-fee share and CAS / advisory mix
  • Transferable, team-based client relationships and documented retention
  • A structured price — cash at close, retention-linked earnout, rollover equity

In multi-partner CPA firms, combined normalizations — the partner-comp scrape, one-time items, related-party rent — routinely change reported EBITDA by 10–30%, so the calculator is often wrong on both the earnings and the multiple.[11]

Earnings basis

SDE or EBITDA? It depends on your size

The single most consequential framing question is which earnings metric applies — gross-fee multiple, SDE, or adjusted EBITDA — and it flips with your size.[10]

Business sizePriced onTypical multipleWhat's going on
Under ~$2M valueSDE1.8x – 3.25x SDESole practitioners and small tax shops; the buyer steps into the owner's seat. Pricing is often quoted as 0.75x–1.5x gross recurring fees, with margin deciding where you land in the band.
$2M – $10M EVAdjusted EBITDA4.0x – 6.0xSmall multi-partner firms with partial management depth; PE add-on interest starts once recurring fees pass ~50% and an advisory line exists.
$10M – $50M EVAdjusted EBITDA6.0x – 8.0xThe median band for PE platform add-ons (Aprio, CRI, Springline, Ascend class); 60%+ recurring fees plus a CAS practice earns the top of the range.
$50M+ EVAdjusted EBITDA7.0x – 11x+Scaled advisory-led platforms; sponsor deals have printed 9x–15x (Poe Group 9x close; Blackstone/Citrin Cooperman ~15x).

Per the IBBA/M&A Source framing, businesses valued under ~$2M are priced on SDE (which adds back the owner's full pay); $2M and above are priced on adjusted EBITDA — in a CPA firm that means the partner-comp scrape: replacing partner draws with a market-rate manager salary before the multiple is applied.[1]

$1.5Mannualized
$250K$8.0M
neutral

60%+ recurring is the premium threshold — firms above it trade 7x–10x, while sub-40% recurring pushes you toward the bottom of the band or gross-fee pricing.

neutral

CAS and advisory revenue is valued at roughly 1.5x–2.0x the multiple of seasonal tax-prep work — if delivery is process-driven, not partner-held.

neutral

A single client above 20–25% of fees triggers a 15–30% discount; above 35%, expect a hard ceiling on cash at close.

neutral

Owner-held relationships are the main reason offers convert to earnout. Second-chair coverage and team-based delivery protect both multiple and cash at close.

Methodology

The three ways a accounting firm gets valued

A credible valuation triangulates across all three. Any single number in isolation is suspect.

Market approach — comparable accounting-firm transactions

The anchor for healthy firms

The market approach values your firm against actual sale prices of comparable accounting practices, and it anchors nearly every deal. The honest caveat is the data: disclosed lower-middle-market accounting comps are genuinely rare — Capstone Partners notes that limited disclosed sector valuations make pricing analysis difficult — so advisors triangulate named platform prints (Blackstone/Citrin Cooperman at ~15x, a Poe Group-advised close at 9x) with advisor-reported multiples in the 4x–8x band.[4][5][8] For context, the 2024 middle-market business-services average was 9.0x EV/EBITDA, with accounting running above the sector median on PE competition.[5]

Income approach — capitalized earnings after the partner-comp scrape

How PE underwrites the number

The income approach capitalizes or discounts forecast cash flow, and in accounting M&A its real work happens in normalization. Buyers replace partner draws with a market-rate manager salary — the partner-comp scrape — and Allan Koltin describes PE applying "a multiple of 7x to 11x" on that scraped number for scaled firms.[3] Sophisticated buyers also model the recurring CAS engagement book separately from episodic tax-season work, because the annuity stream supports a higher value than one-off compliance fees.[6][12]

Asset approach — adjusted net assets

Rarely more than a floor

An accounting firm owns almost no hard assets — the value lives in client relationships, staff, and workflow. The asset approach therefore rarely sets more than a floor and is relevant mainly in distressed or wind-down scenarios; for any profitable practice, the market and income approaches drive the number.[10]

Value drivers

What moves the multiple for a accounting firm

Push you up
  • Recurring fees above 60% of revenue

    +1.0x to +2.0x

    The premium threshold in accounting M&A is 60%+ recurring revenue: firms above it trade at 7x–10x EBITDA while tax-compliance-heavy seasonal shops sit at 4x–6x.[6] Even at the small end, firms with 80%+ recurring fees command 0.2x–0.4x higher revenue multiples than peers.[2]

  • CAS / outsourced-CFO advisory mix

    +0.5x to +1.5x

    CAS and outsourced-CFO revenue is valued at roughly 1.5x–2.0x the multiple of seasonal tax-prep work, because buyers are acquiring an advisory annuity rather than billable hours.[6] The caveat from advisors on both sides: the premium requires transferable, process-driven delivery — advisory revenue held entirely by one partner is priced like owner-dependence risk.[2][12]

  • Client retention above 90%

    +0.5x to +1.0x

    Healthy firms retain 90–95% of clients annually, and buyers underwrite that renewal annuity directly.[6] Documented retention history is also a cash lever: PE deals often carry clawback provisions tied to an 85–90% retention floor, so a clean track record raises the guaranteed portion of the price.[18]

  • Staff depth, leverage, and realization discipline

    +0.5x to +1.0x

    Talent and leadership depth now rank near profitability as a diligence criterion — "many deals fail because of culture, not numbers."[12] Realization rates in the mid-to-upper 80s and healthy staff-to-partner leverage are the most decisive profitability drivers in a CPA firm, and buyers compute both directly in their normalized model.[20]

Push you down
  • Client concentration

    −0.5x to −1.5x

    A single client above 20–25% of gross fees triggers a 15–30% valuation discount or heavy buyer pushback; above 35%, expect a hard ceiling on cash at close and an earnout tied to that specific client's retention.[6] Advisors counsel no single client above ~10% and the top ten below 35% of fees.[6]

  • Owner-held client relationships

    −1.0x to −2.0x

    Non-transferable, owner-held relationships are the main reason offers convert purchase price into earnout rather than cash at close.[12][18] Buyers run a "what if the owner leaves on day one" stress test; if the answer is attrition, the multiple compresses and the contingent share of the price grows.

  • Heavy seasonal tax-compliance mix

    −0.5x to −1.0x

    Firms dominated by annual tax-compliance engagements trade at 4x–6x rather than the 7x–10x premium band, because the cash flow is episodic and re-engagement is not contractual.[6] The fix is converting one-time tax clients to annual engagement letters and monthly-billing service lines before going to market.[6]

  • Attest revenue and APS friction

    −0.25x to −0.75x

    PE buyers acquire CPA firms through an alternative practice structure (APS) that splits the licensed attest entity from the advisory entity they actually own.[19] Significant audit revenue adds independence review, regulatory coordination, and structural separation — more diligence time and less certainty — while low-attest firms move faster to close.[19]

Worked example

A $9M-revenue CPA firm, step by step

An illustrative multi-partner firm with 68% recurring fees, a CAS line at ~35% of revenue, 92% client retention, and two senior managers holding client relationships. Numbers are illustrative, not a specific company.

01

Annual gross fees

$9.0M

Recurring compliance + CAS / outsourced-CFO advisory

02

Adjusted EBITDA

$1.8M

20% margin after the partner-comp scrape and add-backs[3][11]

03

Applied multiple

7.5x

Premium for recurring share, CAS mix, and team-based delivery[6][13]

04

Enterprise value

≈ $13.5M

Adjusted EBITDA × multiple

Indicative result

≈ $13.5M enterprise value

A compliance-heavy variant tells the other half of the story: a $5M-revenue firm at $900K adjusted EBITDA with 45% recurring fees, a top client at 28% of revenue, and no manager in place prices closer to 4.5x — about $4.1M, with a heavier earnout.[6][13] This is illustrative, not an offer or a formal valuation.

Cost & who does it

What a accounting firm valuation costs — and who should do it

Before you anchor on any number, get your normalized earnings right — in a CPA firm that means defending the partner-comp scrape. The right tool depends on why you need the valuation.

Broker / advisor opinion of value

Free – $5,000

Best for

Testing the market, setting expectations

Fast; not certified, and not accepted by the IRS or courts. Many M&A advisors give a preliminary estimate free.

Formal certified appraisal (USPAP)

$5,000 – $30,000+

Best for

Partner buyout, estate or gift tax, litigation, ESOP

Performed by a credentialed appraiser (CVA / ABV / ASA); defensible to the IRS and courts. Partner buy-ins and buyouts are a common trigger in CPA firms.

Quality of earnings (QoE)

$15,000 – $75,000+

Best for

Validating adjusted EBITDA before going to market

Not an audit; tests the partner-comp scrape, add-backs, WIP, and AR — and often pays for itself in re-trade protection.

For most $5M–$200M accounting-firm owners the sequence is: an advisor opinion of value to orient, a sell-side QoE to prepare and defend your adjusted EBITDA — normalizations routinely move reported EBITDA 10–30%, so this is where value is won or lost — and a certified appraisal only if a tax, legal, partner-buyout, or ESOP trigger requires it.[11][16][17] With Ad Astra's verified $1B+ in closed transaction value, a confidential opinion of value is a no-obligation place to start — book a confidential call.

Before you sell

How to increase your valuation before going to market

The gap between a 4x compliance shop and a 7x+ advisory-led firm is built, not born. Over a 12–24 month runway these levers move your multiple — and our value enhancement work is built around them.

  • Lift recurring fees above the 60% threshold

    +1.0x to +2.0x

    Convert one-time tax clients to annual engagement letters and monthly-billing service lines. Crossing the 60% recurring threshold is what moves a firm from the 4x–6x band toward 7x–10x.[6]

  • Build a process-driven CAS / advisory line

    +0.5x to +1.5x

    CAS and outsourced-CFO revenue is valued at roughly 1.5x–2.0x the multiple of seasonal tax-prep work — but only when delivery is systematized and team-based rather than resting on one partner's expertise.[2][6]

  • Make client relationships team-based

    +0.5x to +1.0x

    Build second-chair coverage and manager-level relationships at least 18 months before a sale. It is the single highest-ROI pre-sale investment, because it converts contingent earnout dollars back into cash at close.[12][18]

  • Normalize EBITDA and commission a sell-side QoE

    10–30% earnings swing

    Document the partner-comp scrape, strip one-time items, and normalize related-party rent — combined adjustments routinely change reported EBITDA by 10–30%, and a sell-side QoE keeps buyers from re-cutting them in diligence.[11][17]
