Calculator Disclaimer
This calculator performs mathematical operations on numbers you provide. It does not account for:
- Future changes in rent, expenses, taxes, or interest rates

How it works
Transparency is key. Here are the formulas we use.
Net Operating Income (NOI)
The income the property generates before paying the mortgage. We subtract vacancy first to get Effective Gross Income, then deduct all operating expenses.
Cash Flow
What's left in your pocket each month. This calculator uses a standard amortization formula for the mortgage payment.
Cap Rate
A measure of unleveraged return. It tells you how good the deal is if you paid all cash. Useful for comparing properties regardless of financing.
Cash on Cash Return
The return on the actual dollars you invested (Down Payment + Closing Costs). This accounts for leverage.
