The Break-Even Analysis: Your Most Important Calculation
Before taking out a business loan or expanding, calculate your break-even point.
Break-even formula:
Break-Even Units = Fixed Costs / (Price Per Unit - Variable Cost Per Unit)
Example -- Restaurant:
- Monthly fixed costs (rent, salaries, insurance): $18,000
- Average check per customer: $35
- Variable cost per customer (food, supplies): $14
- Contribution margin: $35 - $14 = $21
Break-even customers per month: $18,000 / $21 = 857 customers/month = 29 customers/day

SBA Loan Rates 2026
SBA loans offer the best rates available to small businesses. Current rates (March 2026):
| Loan Type | Rate Range | Max Amount | Max Term | Best For |
|---|---|---|---|---|
| SBA 7(a) | Prime + 2.25-4.75% | $5,000,000 | 10 years (WC), 25 yrs (RE) | General business |
| SBA 504 | ~6.0-6.5% (fixed) | $5,500,000 | 10-25 years | Equipment, real estate |
| SBA Express | Prime + 4.5-6.5% | $500,000 | 7 years | Fast approval |
| SBA Microloan | 8-13% | $50,000 | 6 years | Startups, micro business |
Prime rate (March 2026): 7.50%
SBA 7(a) at prime + 2.75%: 10.25% -> $50,000/10yr = $660/month
DSCR: Will the Bank Approve Your Loan?
Debt Service Coverage Ratio = Net Operating Income / Total Debt Service
- DSCR > 1.25: Strong -- most banks will approve
- DSCR 1.0-1.25: Acceptable -- some lenders will approve
- DSCR < 1.0: Business cannot service the debt -- loan will be denied
Example: Business generates $8,000/month net income. Loan payment would be $2,500/month.
DSCR = $8,000 / $2,500 = 3.2 -> Excellent, easy approval.
Cash Flow Management: The 13-Week Forecast
The most important financial tool for small business survival:
- List every expected cash inflow for the next 13 weeks (customer payments, loans)
- List every expected cash outflow (payroll, rent, suppliers, loan payments, taxes)
- Calculate ending cash balance each week
- Any week with negative balance needs a solution NOW -- before the crisis
The 3 cash flow emergencies and solutions:
- Slow-paying customers -> Invoice immediately, offer 2/10 net 30, use invoice factoring
- Seasonal revenue dips -> Business line of credit established during good months
- Unexpected expenses -> Business emergency fund (2-3 months operating expenses)
The Business Budget Formula
Revenue - COGS = Gross Profit
Gross Profit - Operating Expenses = EBITDA
EBITDA - Debt Service - Taxes = Net Income
Healthy margins by industry:
- Retail: Gross margin 25-50%, Net margin 2-5%
- Restaurant: Gross margin 65%, Net margin 3-9%
- Software/SaaS: Gross margin 70-85%, Net margin 10-25%
- Construction: Gross margin 15-25%, Net margin 2-8%
- Professional services: Gross margin 50-70%, Net margin 15-30%
