Compare rent, vacancy, expenses, and loan payments clearly. Reveal annual margins and break-even occupancy quickly. Judge whether projected income can cover ownership costs sustainably.
The chart compares effective income against operating costs, debt service, and resulting annual cash flow.
| Property | Purchase Price | Monthly Rent | Vacancy | NOI | Annual Cash Flow | Break-Even Occupancy | Status |
|---|---|---|---|---|---|---|---|
| Townhome A | 250,000 | 2,400 | 5% | 15,462.00 | -3,493.57 | 105.67% | Above break-even risk |
| Duplex B | 315,000 | 3,450 | 4% | 24,108.00 | 4,220.80 | 82.14% | Tight cushion |
Potential Gross Income = (Monthly Rent + Other Monthly Income) × 12
Effective Gross Income = Potential Gross Income × (1 − Vacancy Rate)
Variable Operating Costs = Effective Gross Income × (Management + Maintenance + Capital Reserve Rates)
Fixed Operating Costs = HOA + Utilities + Taxes + Insurance + Other Fixed Costs
NOI = Effective Gross Income − Total Operating Costs
Annual Cash Flow = NOI − Annual Debt Service
Break-Even Occupancy = (Fixed Operating Costs + Debt Service) ÷ [Potential Gross Income × (1 − Variable Cost Rate)]
Monthly Break-Even Income = Annual Break-Even Income ÷ 12
Cash-on-Cash Return = Annual Cash Flow ÷ Initial Cash Invested
Cap Rate = NOI ÷ Purchase Price
Break-even means the property’s income is just enough to cover operating costs and financing. At that point, cash flow is effectively zero before taxes.
It shows the percentage of gross income capacity needed to cover costs. Lower break-even occupancy usually means the property can tolerate more vacancy risk.
Yes. It estimates monthly mortgage payments from the loan amount, interest rate, and term, then includes annual debt service in the final break-even view.
Management, maintenance reserve, and capital reserve are treated as percentages of collected income. These costs typically move with occupancy and rent collection.
NOI excludes financing and reflects property performance before debt. Cash flow goes one step further by subtracting annual debt service from NOI.
If required income is greater than the property’s maximum modeled income, break-even occupancy can exceed 100%. That usually signals an unworkable deal under the current assumptions.
It is best suited to income-producing real estate such as single-family rentals, duplexes, condos, and small multifamily properties with recurring rent income.
No. Test optimistic, expected, and conservative cases. Small changes in rent, vacancy, and financing can materially change the break-even picture.
