Agency Fee Break-Even Calculator

This worksheet compares an agency route with an alternative over one period. It exposes fee and placement assumptions; it does not predict hiring success or ROI. Synthetic figures illustrate arithmetic, not legal or accounting advice.

Start with the measurement boundary

Freeze the question: "Over [period], when does this agency route cost no more than [alternative]?" Record scope, currency and dates; compare one proposal with one alternative.

There are two related outputs:

Output	What it answers	Denominator
Forecast cost per placement	What each route costs if the forecast number of completed placements occurs	Forecast completed placements for that route, `N_f`
Placement-volume break-even	At what forecast placement count the two routes have equal total cost	Forecast placements, `N_f`; not profiles, interviews or applications

Use completed placement consistently. Define the event before modelling and align it with the invoice trigger. Profiles, interviews and accepted briefs are not placements.

SHRM's public cost-per-hire guidance (6 December 2023; checked 4 September 2026) divides defined internal and external costs by a stated hire count. This adaptation is not an SHRM benchmark.

Forecast denominator rules

Label the denominator state explicitly:

Observed placements (H_o): qualifying events in a closed historical period; this describes past cost only.
Forecast placements (N_f): expected events for the decision period, with method, range, owner, version and evidence.
Approved target (H_t): a headcount or requisition plan, not a forecast unless its owner approves that interpretation.

Profiles, shortlists, interviews, offers and openings are not placements. If N_f = 0 or unknown, show totals and withhold ratios; never divide by zero or convert a target.

Copy the assumptions worksheet

Complete one row per role/group. Give non-zero inputs a unit, owner, source and date; mark missing inputs unknown, not zero. Separate proposal terms from volume assumptions.

Input	Symbol	Definition	Evidence or owner
Forecast placements	`N_f`	Expected qualifying placement events in the period; include the forecast method and range	Finance or recruiting analyst, dated forecast
Agency fixed cost	`F_A`	Retainer, engagement fee, minimum commitment and non-refundable milestones allocated to this scope	Agency proposal or signed terms
Agency fee rate	`r_A`	Percentage applied to the proposal's stated fee base; use `0` only when the written terms say so	Agency proposal or signed terms
Fee base per placement	`C_i`	Salary, guaranteed cash compensation, fixed amount or other defined base for placement `i`	Offer record and agency terms
Agency placement charges	`r_A x C_i`	Variable charge when the agreed placement trigger occurs	Agency proposal or signed terms
Agency expenses	`E_A`	Agreed advertising, travel, checks, taxes or other supplier charges, with treatment stated	Quote, invoice or contract
Agency-management labour	`I_A`	Internal briefing, feedback, coordination, approvals and dispute administration	Time record and loaded rates
Alternative fixed cost	`F_B`	Internal setup, advertising, allocated platform commitment or other fixed cost for the comparison route	Budget, invoice or allocation rule
Alternative variable cost	`V_Bi`	Internal labour, tools, checks and other cost that changes with each forecast placement	Time records, rates and invoices
Alternative expenses	`E_B`	Advertising, checks, taxes or other supplier charges for the comparison route that are not already counted in its fixed or variable cost, with treatment stated	Quote, invoice or contract
Alternative-route internal labour	`I_B`	Internal briefing, search, contact, assessment, records and approvals for the comparison route that do not change with each placement and are not already counted in its fixed or variable cost	Time record and loaded rates
Credits and refunds	`R_A`, `R_B`	Verified amounts that reduce a route's cost under stated conditions	Credit note or contract remedy
Comparison scope	`S`	Work included in both totals, and work excluded or separately reported	Decision owner

Distinguish placement fees from retainers. Robert Half's explainer (checked 4 September 2026) describes contingency fees after a successful hire and retainers paid upfront, sometimes with a later success payment. Written agency terms govern. Our guide to contingency recruiting works the fee math on a US$100,000 salary. A fractional recruiter is a third route: a part-time recruiter paid by the hour, by the month or per hire.

For the alternative, include team-owned briefing, search, contact, assessment, records and approvals. A sourcing tool may reduce discovery effort but does not remove those responsibilities.

Apply the formulas

Calculate internal labour with each contributor's approved loaded rate:

Internal labour = SUM(hours_i x loaded hourly rate_i)

Agency variable placement cost_i = agency rate (r_A) x fee base (C_i)

Use the written amount when the proposal specifies a fixed charge:

Agency variable placement cost_i = fixed placement charge_i

Agency total (A) = F_A + SUM(agency variable placement cost_i) + E_A + I_A - R_A

With one fee base C and rate r_A:

A = F_A + (N_f x r_A x C) + E_A + I_A - R_A

Alternative total (B) = F_B + SUM(alternative variable cost_i) + I_B + E_B - R_B

With stable per-placement cost V_B:

B = F_B + (N_f x V_B) + I_B + E_B - R_B

Keep internal labour visible, avoid adding it twice, and use the same scope, period and currency for both routes.

Forecast cost per placement

Only when N_f > 0:

Agency forecast cost per placement = A / N_f

Alternative forecast cost per placement = B / N_f

These are conditional route-cost outputs, not candidate, speed, retention, productivity or return estimates.

Solve for placement-volume break-even

Under the stable-variable-cost model, solve A = B for N*:

N* = (F_A + E_A + I_A - R_A - F_B - E_B - I_B + R_B) / (V_B - V_A)

V_A and V_B are variable costs per placement. Preserve the unrounded result; a fraction is only a mathematical threshold.

When V_B - V_A = 0, compare fixed costs directly: lower is always cheaper, equal ties, higher never breaks even. Explain negative thresholds; do not force a positive number.

For changing bases, staged fees, refunds or credits, use row totals across N_f = 0, 1, 2....

Synthetic scenarios, labelled as illustrations

Examples use synthetic planning currency CU; they are not benchmarks or performance predictions.

Scenario A: fixed agency commitment, one placement

Agency: F_A = CU4,000, 15% of a CU100,000 base, E_A = CU300, I_A = CU700. Alternative: F_B = CU800, V_B = CU2,400, I_B = CU500, E_B = CU0; assume one placement and no credits.

V_A = 15% x CU100,000 = CU15,000

A = CU4,000 + CU15,000 + CU300 + CU700 = CU20,000

B = CU800 + CU2,400 + CU500 = CU3,700

At N_f = 1, the agency route costs more under this scope; it is not a hiring or value claim.

Scenario B: solving the threshold

Use F_A + E_A + I_A = CU6,000, V_A = CU2,000, F_B + E_B + I_B = CU1,000 and V_B = CU5,000:

N* = (CU6,000 - CU1,000) / (CU5,000 - CU2,000) = 1.67 placements

The agency route is below the modelled alternative at two or more placements, but not one. Validate the count, trigger, scope and capacity; the threshold guarantees nothing.

Scenario C: the denominator is not available

With three approved openings but no evidence for qualifying placements, record N_f = unknown, not 3; show route totals, request a dated forecast range and withhold per-placement results. Openings are not completed placements.

Run sensitivity and set stop conditions

Change one driver at a time, then add an owner-approved combined low/base/high case. Test fee rate/base, retainer, expenses, internal hours, alternative variable cost, placements, start-date trigger and credits.

Driver	Low case	Base case	High case	Required note
Forecast placements `N_f`	Lower dated scenario	Analyst's approved case	Higher dated scenario	Method, period and owner
Agency fee base `C_i`	Lower approved compensation case	Role-approved case	Higher approved compensation case	What compensation is included
Agency fee rate or charge	Written lower case, if applicable	Proposal case	Written higher or trigger case	Do not invent a market range
Internal coordination hours	Observed lower case	Current estimate	Extra review, delay or dispute case	Contributor and loaded rate
Alternative variable cost `V_B`	Verified lower workload	Current scope	Added outreach or assessment work	Keep tool and labour separate
Credits or refunds	Contractually usable	No credit unless verified	Credit excluded or delayed	Conditions and timing

Report a range when a material input is a range; do not average away an unknown trigger or choose a favourable single point.

Failure signal	Action	Stop condition
The fee base or invoice trigger is missing	Ask the agency for written terms and preserve the item as unknown	No approval of a break-even claim until the trigger and base are defined
`N_f` is zero, a target or an unsupported forecast	Report route totals and label the denominator unavailable	No per-placement result or threshold used for a buying decision
`V_B - V_A` is zero or changes sign across scenarios	Compare route totals at each valid placement count	No single break-even placement number
A retainer, fee, tax, credit or internal hour appears twice	Reconcile each line to the invoice, quote or time record	Scope owner confirms one non-overlapping numerator
Replacement terms, candidate ownership or exclusivity are unclear	Request the written remedy and model the no-remedy case	No risk-adjusted comparison until material terms are known
Routes cover different work	Add missing work or label a scope-limited comparison	Decision owner accepts equivalent scope or pauses the comparison

Where Talent Summoner fits

Talent Summoner is our candidate-sourcing and ranking product, not an agency. Its candidate-sourcing workflow returns a ranked shortlist from a role brief; your team chooses contact, checks evidence, handles replies, assesses candidates and decides.

Use current pricing as the dated source for any tool line. Record purchase mode, allocation, verification date and remaining work. The charge is not an agency fee, guarantee or ROI forecast; Talent Summoner is not an ATS or application pipeline.

Next step

Take one proposal and alternative, complete the worksheet across the placement range, and resolve unknowns with an owner and source. Take the tool line from current pricing on the day you fill in the worksheet; the decision owner makes the call.

What is the break-even point for a recruitment agency?

It is the forecast placement count where both routes have equal total cost under the same scope. Use the threshold equation only with defined, non-zero variable-cost difference.

What should be the denominator in an agency fee calculator?

Use qualifying completed placements under one event rule. Label forecast N_f with method, range, owner and evidence; never use profiles, interviews, offers or openings.

How do I calculate an agency placement fee?

Apply the written rate to each fee base, or use the proposal's fixed charge. Add retainers, expenses and internal time; subtract verified credits. The contract trigger controls.

Is a lower agency cost proof of better ROI?

No. It compares modelled route costs, not quality, hiring success, retention, productivity, speed, revenue or ROI. Keep scope and outcome evidence separate.

What if I do not know how many placements to expect?

Mark N_f unknown, report route totals, and obtain a dated method or range. Do not divide by zero or convert a headcount target into a forecast.

Can Talent Summoner replace a recruitment agency in this calculation?

No. It may be one tool line while your team owns outreach, verification, assessment, records and decisions. It is not an agency, ATS or ROI guarantee.
