Business Plan Consulting Expected Value & Break-Even Calculator

Compare self-preparation and consulting-assisted success probabilities, complete internal and delay costs, base and contingent fees, expected net value, and break-even thresholds.

The amounts, probabilities, and hours below are fictional examples—not market benchmarks or official award rates. Replace them with the actual notice, aligned quote and contract, comparable submission outcomes, and internal time records.

Opportunity value and common cost

Official-source and model boundary

K-Startup program notices, Korea ON-line E-Procurement System notices, GAO-20-195G cost guidance, and HM Treasury Green Book 2026 were checked on 2026-08-05. The Korean portals define where to verify each opportunity; GAO and the Green Book only support complete-cost, expected-value, and sensitivity methods. This calculator supplies or guarantees no award probability, consultant performance, market fee, eligibility, proposal score, or contract award. It does not justify fabricated content, false evidence, or responsibility-free ghostwriting; the applicant remains responsible for the final submission.

Related calculators

Compare business-plan consulting by expected value, not by quote alone

A consulting quote is visible, while founder time, employee review cycles, missed deadlines, and the cost of executing a successful project are easy to overlook.
The opposite mistake is equally costly: treating a consultant's headline success rate as a guarantee and using it to justify any fee.
This calculator treats self-preparation and consulting-assisted preparation as two investment alternatives, then compares their probability-weighted net value on the same complete-cost boundary.
It does not predict an award, certify a consultant, or replace the eligibility and evaluation rules in an official notice.

Decisions this model can support

Grant applications

Use the economic value you can actually retain after matching funds, delivery, reporting, and compliance costs rather than the maximum award shown in a notice.

Loans and guarantees

Use interest savings, timing benefits, and financing access after fees instead of treating borrowed principal as profit.

Public or private bids

Use expected contribution margin after fulfillment costs rather than contract revenue, which prevents sales volume from being mistaken for value.

Investor materials

Estimate the value of faster financing, added runway, or avoided failure while deducting the work required after a successful raise.

Expected-value model

Separate benefits and fees that occur only after success from preparation costs that occur regardless of the outcome.
A contingent success fee is probability-weighted, while the base fee, add-ons, internal labor, and delay cost are deducted in full.

1. Net benefit if successful

Net success benefit = opportunity economic value − post-selection execution cost

2. Self-preparation expected net value

Self EV = self success probability × net success benefit − self internal labor cost − self delay cost

3. Consulting-assisted expected net value

Consulting EV = consulting success probability × net success benefit − base fee − add-ons − consulting internal labor cost − consulting delay cost − probability-weighted success fee

4. Incremental consulting value

Incremental EV = consulting EV − self EV

Build defensible inputs

Opportunity value and execution cost

Enter the amount your organization can economically retain, not the largest advertised award or total contract revenue.
Deduct mandatory matching funds, fulfillment, hiring, reporting, travel, tax, and compliance work that arises only after success.

Success probabilities

Start with completed applications similar in program, company stage, sector, and evaluation round.
Ask whether a consultant's published rate includes screened-out leads, withdrawals, incomplete submissions, and repeat clients before treating it as comparable evidence.

Internal effort

Estimate drafting, data response, interviews, review meetings, revision count, and hours per revision separately for both alternatives.
Use a reasonable loaded hourly opportunity cost that reflects work displaced by the application without exaggerating idle or non-billable time.

External and delay cost

Include design, translation, printing, presentation support, travel, and applicable tax when they sit outside the base quote.
Use delay cost only when a later submission or decision plausibly defers revenue, financing, launch, or another time-sensitive opportunity.

Worked examples in KRW and USD

The Korean default uses KRW 200,000,000 of opportunity value, KRW 60,000,000 of post-selection execution cost, a 25% self probability, and a 38% consulting probability.
Its complete preparation costs are KRW 13,200,000 for self-preparation and KRW 20,850,000 before the contingent fee for consulting.
The English calculator uses the same method with independent USD defaults so the interface does not silently convert currencies.

English USD exampleUSD 7,700USD 17,745USD 10,04528.341346%

For the KRW default, consulting needs about 7.310606 percentage points of improvement above the 25% self probability to reach parity, and the maximum base fee is KRW 19,510,000 if all other inputs stay fixed.
For the USD default, consulting has USD 10,045 of incremental expected value and reaches parity at approximately 28.341346% probability.
These numbers are deterministic examples, not observed market averages or recommended prices.

Read the break-even outputs

  1. Consulting parity probability is the consulting-assisted success probability required to match the self-preparation expected net value at the current fee and effort assumptions.
    Compare it with evidence from a genuinely similar client cohort, not an unqualified headline rate.
  2. Maximum base fee is the most you could pay upfront before the two alternatives reach parity, assuming every other input remains unchanged.
    Tax and optional services can push the complete external cost above this boundary even when the quoted base fee appears acceptable.
  3. Opportunity-value crossover shows how large the net opportunity must become before the additional probability can recover the consulting cost.
    It helps distinguish a proportionate engagement from an oversized package applied to a small opportunity.

Stress-test assumptions before signing

A single expected value can look precise while resting on uncertain probabilities and opportunity estimates.
The result panel automatically recalculates seven scenarios so you can see which assumption changes the decision.

  • Reduce the consulting probability by 5 and 10 percentage points.
  • Add 7 and 30 days of consulting delay.
  • Increase the base fee by 20%.
  • Reduce the opportunity economic value by 20%.

Use stages when the conclusion is fragile

If modest downside assumptions turn incremental EV negative, consider a paid diagnostic, outline review, draft, and presentation support as separately accepted milestones.
Define deliverables, evidence standards, interviews, revisions, response deadlines, and acceptance criteria instead of asking a provider to guarantee a selection result it cannot control.

Seven-step workflow

  1. Read the official notice or request for proposal and estimate retained economic value after mandatory execution cost.
  2. Record a self-preparation probability from comparable completed applications, using a range when the sample is weak.
  3. Request the consultant's completed and successful case counts, cohort definition, period, screening rules, and withdrawal treatment in writing.
  4. Separate the base fee, contingent fee, add-ons, tax, travel, translation, design, and presentation support.
  5. Estimate drafting, data response, revision, and delay inputs separately for self and consulting alternatives.
  6. Review incremental EV, parity probability, maximum fee, and every downside scenario together.
  7. Save the source, assumption owner, and calculation date, then update the model when the notice, quote, or schedule changes.

Pre-contract evidence checklist

Verify Completed and successful comparable engagements over a defined recent period.

Verify Treatment of screened leads, incomplete work, withdrawals, and repeat applications.

Verify Named delivery team, roles, availability, and expected effort instead of credentials alone.

Verify Primary sources for market, customer, competitor, and financial claims.

Verify Deliverable list, editable file formats, data ownership, and reuse rights.

Verify Interview count, revision limit, response deadlines, and schedule-change rules.

Verify Base fee, contingent fee, add-ons, tax, refund terms, and the definition of success.

Verify Confidentiality, access control, retention period, deletion, and no-reuse obligations.

Exclude fabricated evidence and guaranteed-award claims

A legitimate adviser can structure facts, challenge assumptions, document research, and improve clarity, but the applicant remains responsible for the truth and eligibility of the final submission.
Reject services that propose fabricated revenue, invented customer interviews, manipulated quotes, copied plans, undisclosed conflicts, or access to decision-makers as a substitute for merit.

Share sensitive technical, customer, personal, and financial information only when needed, with written confidentiality, access, retention, deletion, and reuse restrictions.
A positive calculated EV never overrides legal, ethical, security, or procurement requirements.

Frequently asked questions

Where should the consulting success probability come from?

Begin with your own comparable completed applications. Cross-check a provider only with a cohort that matches the program, company stage, sector, and evaluation round, and use downside ranges when the sample is small.

Is a USD 100,000 grant worth USD 100,000?

Not necessarily. Deduct matching funds, fulfillment, hiring, reporting, travel, tax, and compliance work that becomes necessary after selection to estimate retained economic value.

How do I enter a percentage-based success fee?

Convert the percentage into the fixed amount expected to be payable on success. Enter that success-state amount once; the calculator applies the consulting probability to derive its expected cost.

Does a zero base fee mean the service is free?

No. Contingent fees, add-ons, internal meetings, data preparation, delay, tax, and rights over deliverables may still create material economic cost.

Should I sign whenever incremental EV is positive?

No. Test downside scenarios, cash-flow affordability, provider capacity, evidence quality, confidentiality, deliverables, acceptance, and refund terms before making a contract decision.

What does a parity probability above 100% mean?

The current fee and benefit assumptions cannot make consulting outperform self-preparation at any feasible probability. Reduce scope or cost, or revisit the evidence behind opportunity value and effort savings.

Can this model evaluate a provider after delivery?

It is primarily a planning model. For evaluation, preserve the original assumptions and compare actual deliverables, effort, timing, complete cost, and outcome using a separately defined performance record.

The input evidence matters more than a precise-looking result

Gather the official notice, complete quote, comparable outcomes, and time records before entering values.
A decision that remains stable across the base and downside scenarios is easier to explain, negotiate, revisit, and improve than one based on intuition alone.
