How to Use This Calculator

  3. Enter annual mortgage debt service.
  4. Review Cap Rate, Cash-on-Cash return, and net cash flow.

The Mathematical Formula & Variables

Cap Rate = Net Operating Income / Price; Cash-on-Cash = Cash Flow / Initial Cash

Step-by-Step Worked Example

Scenario: $300,000 property rented for $2,500/mo ($30k/yr) with 32% expenses.

  1. Operating expenses = 32% of $30k = $9,600.
  2. NOI = $30,000 - $9,600 = $20,400.
  3. Cap rate = $20,400 / $300,000 = 6.80%.
  4. After $13,920 debt: Net cash flow = $6,480/yr.

Result: 6.80% Cap Rate, $540/mo Cash Flow
