Vacancy Loss
Vacancy Loss = Gross Scheduled Income × Vacancy Rate

Effective Gross Income
Effective Gross Income = Gross Scheduled Income − Vacancy Loss

Operating Expenses
Operating Expenses = Taxes + Insurance + HOA + Utilities + Reserves + Advertising + Miscellaneous

NOI
NOI = Effective Gross Income − Operating Expenses

Monthly Cash Flow
Monthly Cash Flow = NOI − Monthly Debt Service

Cap Rate
Cap Rate = Annual NOI ÷ Total Project Cost × 100

Cash on Cash Return
Cash on Cash Return = Annual Cash Flow ÷ Cash Invested × 100

DSCR

FAQs

1. What does this calculator estimate?

It estimates rental property cash flow using income, vacancy, financing, reserves, and recurring expenses. It also shows cap rate, cash on cash return, DSCR, and break-even occupancy.

2. Why is cash flow different from NOI?

NOI excludes mortgage payments and focuses on property operations. Cash flow subtracts debt service from NOI, showing the money left after both expenses and financing.

3. Should I include reserves?

Yes. Maintenance and capital expenditure reserves help model real ownership costs. Leaving them out can make a property look stronger than it really is.

4. What is a good DSCR?

Many investors and lenders prefer a DSCR above 1.20. Higher values generally mean the property has more income cushion relative to annual debt obligations.

5. Does cap rate include financing?

No. Cap rate is based on NOI and property cost basis. It helps compare assets before loan structure changes the final cash flow.

6. What does break-even occupancy mean?

It shows how much occupancy the property needs to cover operating expenses and debt service. Lower break-even occupancy usually indicates a safer income profile.

7. Can this calculator compare different deals?

Yes. Run each property with consistent assumptions, then compare annual cash flow, cap rate, DSCR, expense ratio, and cash invested to rank opportunities.

8. Are taxes and appreciation included?

This version focuses on operating cash flow and financing. It does not estimate appreciation, depreciation, tax strategy, or sale proceeds.
