Direct answer: break-even is necessary but not sufficient
For a ROBS-funded company, the most defensible break-even analysis starts with SBA's standard small-business definition: total cost and total revenue are equal, so there is no gain or loss. SBA gives the unit formula as fixed costs divided by price minus variable cost and the sales-dollar formula as fixed costs divided by contribution margin.[2]
That formula is necessary, not sufficient. A ROBS transaction changes retirement-plan assets into employer stock of a C corporation. IRS describes the arrangement as the plan using rollover assets to buy stock of the new C Corporation business, with recurring plan and valuation issues if the arrangement is not operated correctly.[1] A complete ROBS break-even file therefore separates business viability from tax, plan, fiduciary, valuation, and retirement-concentration boundaries.
Four break-even definitions to keep separate
Each definition answers a different decision question. Mixing them can make a business look viable because one threshold is met while cash runway, capital recovery, or retirement concentration remains unresolved.
Use the comparison grid below to keep the monthly operating model, corporate cash test, upfront capital recovery, and retirement-risk boundary in separate columns.
Core formulas and inputs
Use one monthly model and label every input. The basic unit formula is fixed costs ÷ (price per unit − variable cost per unit). The sales-dollar formula is fixed costs ÷ contribution-margin ratio. SBA notes that this is an estimate for lender viability and business planning rather than a calculation that can be 100% accurate before all costs and production occur.[2]
| Input | ROBS-specific handling |
|---|---|
| Fixed costs | Rent, salaried payroll, insurance, software, minimum utilities, provider administration, valuation support, Form 5500 support, CPA and legal retainers. |
| Variable costs | Cost of goods, hourly labor tied to volume, card fees, royalties, shipping, supplies, commissions, and other costs that move with sales. |
| Debt service | Include SBA or other loan payments in cash break-even, but do not pretend ROBS capital itself is debt. |
| Owner salary | Include reasonable W-2 salary as operating cost when the owner works for the C corporation. Do not count salary as investment return to the plan. |
| Retirement risk | Show separately: percentage of retirement assets in plan-owned employer stock, remaining liquidity, and downside value if the business fails. |
Scenario calculations with assumptions and exclusions
These examples use hypothetical inputs and rounded outputs. They exclude taxes on later retirement-plan distributions, inflation, personal living expenses, future investment advisory fees, state law, transaction-specific valuation discounts, bankruptcy recoveries, and any guarantee of business or market performance.
Unit break-even before ROBS-specific costs
Formula: Fixed costs $42,000 ÷ ($120 price − $48 variable cost) = 583.33 units, rounded up to 584 units.
Model result: 584 units.
Sales-dollar break-even after fixed provider and professional costs
Formula: Annual ROBS support cost $1,800 ÷ 12 = $150; adjusted fixed costs $42,000 + $150 = $42,150; $42,150 ÷ 60% contribution margin = $70,250 sales.
Model result: $70,250 monthly sales.
Break-even difference when debt service is added
Formula: ($42,000 fixed costs + $6,500 monthly debt service) ÷ 60% margin = $80,833 sales; $80,833 − $70,250 = $10,583 additional monthly sales.
Model result: $10,583 additional monthly sales.
Risk boundary using retirement concentration
Formula: $190,000 plan-owned employer stock ÷ $260,000 total retirement assets = 73.08%, rounded to 73%.
Model result: 73% retirement concentration.
Independent arithmetic: $120 − $48 = $72 contribution per unit; $42,000 ÷ $72 = 583.33, rounded up to 584. $1,800 ÷ 12 = $150; $42,150 ÷ 0.60 = $70,250. ($42,000 + $6,500) ÷ 0.60 = $80,833; $80,833 − $70,250 = $10,583. $190,000 ÷ $260,000 = 73.08%, rounded to 73%.
Opportunity cost and capital recovery are not the same
Capital recovery asks when the business earns back setup and launch costs. Opportunity cost asks what the retirement assets might have done in the next-best path. DOL describes defined contribution balances as contributions plus or minus investment gains or losses, SEC Investor.gov defines diversification as spreading money among investments, and Investor.gov describes investment risk as uncertainty or potential financial loss.[3][4][5]
Do not convert opportunity cost into a false invoice. A forgone portfolio path is an assumption-based benchmark. It belongs beside the break-even model so the owner can see that a business can cover monthly costs while still leaving the retirement account concentrated in one privately held company.
Risk boundaries before relying on the break-even result
A positive break-even model does not show that the ROBS has been blessed by a government agency. It does not prove that employer stock was bought for adequate consideration, that plan documents are being followed, that eligible employees are handled correctly, that the owner's salary is reasonable, or that a later sale will repay the retirement plan.
Set boundaries before the plan buys employer stock: maximum retirement concentration, minimum household liquidity outside the business, minimum corporate cash after closing, downside revenue trigger, maximum monthly cash burn, date for professional review, valuation-update triggers, and a stop rule if sales miss the model. IRS ROBS project findings reported failed or failing businesses and lost retirement assets, so the downside case should be part of the main file rather than a footnote.[1]
Decision framework for a ROBS break-even file
A decision-ready file should move from the business model to ROBS-specific costs, downside cases, alternatives, separate ledgers, and professional questions in order.
- Build the operating model with fixed costs, variable costs, units, price, margin, and monthly timing.
- Add ROBS-specific fixed costs, professional fees, valuation support, Form 5500 support, tax preparation, and owner salary where applicable.
- Run baseline, downside, and severe cases. Show the revenue, unit, cash runway, and reserve effect for each case.
- Compare ROBS with debt, taxable withdrawal, personal savings, outside investors, waiting, or a smaller purchase using the same date range.
- Keep the retirement ledger separate from the corporate ledger: plan-owned stock, personal wages, corporate cash, and personal savings are different buckets.
- Name unresolved professional questions for the CPA, ERISA attorney or plan professional, valuation professional, lender, and business advisor before treating the model as decision-ready.
ROBS break-even analysis FAQ
This page is educational. These answers do not decide legal eligibility, tax treatment, fiduciary prudence, valuation support, lending approval, or investment suitability for a specific owner.
Does reaching break-even mean a ROBS is approved or suitable?
No. Break-even only means the modeled revenue covers the modeled costs under stated assumptions. It does not approve the ROBS structure, prove fiduciary prudence, validate employer-stock value, remove compliance duties, or make the business suitable for a specific retirement account.[1][2][5]
Should ROBS setup fees and annual administration be in the break-even model?
Yes, when they are paid by the corporation or plan and affect cash flow or reasonable plan expenses. Keep provider fees, valuation costs, Form 5500 support, tax preparation, and legal fees visible rather than hiding them inside general overhead.[1][6]
Should opportunity cost be treated as a monthly operating expense?
No, not when the model is measuring business operating break-even. Opportunity cost is a comparison against the retirement-portfolio path, not a vendor bill. Show it beside the operating break-even so the reader sees both business cash viability and retirement tradeoff.[3][4][5]
What is the most defensible ROBS break-even definition?
Use more than one definition: operating break-even for revenue versus operating costs, cash break-even for debt service and fixed ROBS support costs, capital recovery for setup and professional fees, and retirement-risk break-even for the plan-owned stock and forgone portfolio path.[1][2][3]
