A Texas-based freelance graphic designer earns $140,000 net profit/year from client work. She's evaluating whether to stay as a sole proprietor, form an LLC, or elect S-Corp status to reduce self-employment taxes.
Takeaway: S-Corp saves $8,300/year but adds ~$1,500-$3,000 in accounting fees (payroll, extra returns). Break-even is around $80-90K net profit. Below that, the overhead eats the savings. Texas has no state income tax, so the benefit is purely federal SE savings.
LLC annual fees range from $0 (Ohio) to $800 minimum (California, even for zero-revenue LLCs). Delaware C-Corp is standard for VC-backed companies but adds registered agent costs (~$300/yr) for out-of-state entities. The "best" structure is state-specific.
S-Corps cannot have more than 100 shareholders, cannot have non-US shareholders, and cannot have corporate shareholders. Violating these rules (e.g., adding a foreign investor) terminates S-Corp status retroactively, potentially creating a large unexpected tax event.
The IRS requires S-Corp owner-employees to pay themselves a "reasonable salary" before taking distributions. There is no fixed formula — the IRS looks at industry benchmarks, duties, and hours worked. Setting the salary too low is a common audit trigger for S-Corps.
Business break-even models track revenue vs. direct costs. They rarely factor in the owner's time as a cost. If you're working 60 hours/week at imputed $50/hour, your "profitable" business may be paying you $12/hour after the opportunity cost calculation.
Break-Even CalculatorA service business valued on EBITDA multiples (2-4×) gets a very different number than one valued on SDE (seller's discretionary earnings) or discounted cash flow. Buyers and sellers typically use different methods to argue their preferred price. This calculator uses a single method.

Start with current revenue, then apply a growth rate. For compound growth: Future Revenue = Current × (1 + Growth Rate)^Periods. Add seasonal adjustments for cyclical businesses.
Early-stage startups: 20-100%+ annually. Established small businesses: 5-15%. Mature companies: 2-7%. High-growth SaaS/tech: 50-200%+. Always validate against market data.
Month-over-Month (MoM) is the percentage change from one month to the next. Year-over-Year (YoY) compares the same period in consecutive years. Investors often focus on YoY to remove seasonal noise.
Estimate the number of customers × average deal size × purchase frequency. This is more accurate than top-down (taking a % of a large market) because it's grounded in real sales assumptions.
Revenue run rate extrapolates current periodic revenue to an annual figure. If you earned $50,000 last month, your annual run rate is $600,000. It assumes consistent performance but ignores seasonality.
Use comparable businesses, industry benchmarks, and bottom-up modeling. Estimate customer acquisition rate, average transaction value, and repeat purchase frequency. Build conservative, base, and optimistic scenarios.
Churn rate is the percentage of customers who stop buying each period. A 5% monthly churn means losing half your customers annually. Net revenue growth requires new customer acquisition to exceed churn losses.
MRR (Monthly Recurring Revenue) is total recurring revenue per month. ARR (Annual Recurring Revenue) is MRR multiplied by 12. SaaS and subscription businesses use these metrics to track predictable revenue.
Forecast 12-24 months for operational planning and 3-5 years for strategic planning or investor presentations. Accuracy decreases significantly beyond 12 months, so use ranges rather than single estimates.
A bottom-up forecast builds projections from unit sales, pricing, and customer counts. A top-down forecast starts with total market size and estimates your capture rate. Bottom-up is more accurate for established businesses while top-down suits early-stage ventures.
Compound Growth: Revenue × (1 + Rate)^n
n = number of periods
