A Cash-on-Cash Return Calculator is a real estate investment tool that measures how much cash income a property generates relative to the actual cash you’ve invested.
Unlike cap rate, which ignores financing, cash-on-cash return takes your mortgage and financing structure into account.
Formula
Cash-on-Cash Return=Total Cash InvestedAnnual Pre-Tax Cash Flow×100%
Where:
- Annual Pre-Tax Cash Flow = Rental income − Operating expenses − Debt payments (mortgage principal and interest)
- Total Cash Invested = Down payment + closing costs + renovation costs + other upfront cash expenses
Example
Suppose you buy a rental property for $300,000:
- Down payment: $60,000
- Closing costs: $5,000
- Renovations: $10,000
Total cash invested:60,000+5,000+10,000=75,000
Annual figures:
- Rental income: $30,000
- Operating expenses: $10,000
- Mortgage payments: $8,000
Annual pre-tax cash flow:30,000−10,000−8,000=12,000
Cash-on-cash return:75,00012,000×100=16%
So your cash-on-cash return is 16% per year.
Cap Rate vs. Cash-on-Cash Return
| Metric | Includes Financing? | Measures |
|---|---|---|
| Cap Rate | No | Property’s operating performance |
| Cash-on-Cash Return | Yes | Return on the actual cash you invested |
For example, two investors could buy the same property:
- Investor A pays all cash.
- Investor B puts 20% down and gets a mortgage.
Both would have the same cap rate, but their cash-on-cash returns could be very different.
When to Use It
Cash-on-cash return is useful when:
- Comparing leveraged real estate investments.
- Evaluating rental properties.
- Determining whether financing improves your returns.
- Comparing real estate investments with other investments such as stocks or bonds.
