Cash-on-Cash (CoC) Yield Defined
Cash-on-Cash yield is arguably the most critical metric for active real estate investors. It measures the pure cash return on the actual cash invested in a property over a one-year period.
Unlike Internal Rate of Return (IRR) or Total ROI, CoC ignores future property appreciation, loan principal paydown, and complex depreciation tax benefits. It answers one simple question: *'If I put $100,000 into this deal today, how much actual cash lands in my bank account over the next 12 months?'*
The Mathematical Formula
The formula requires isolating the net cash flow generated specifically from operations:
\[ \text{Cash-on-Cash Yield} = \frac{\text{Annual Pre-Tax Cash Flow}}{\text{Total Cash Invested}} \times 100 \]
Component Breakdown
1. **Annual Pre-Tax Cash Flow**: This is the Net Operating Income (NOI) minus the annual debt service payments (both mortgage principal and interest).
2. **Total Cash Invested**: This is not just the down payment. It includes the down payment, loan origination fees, closing costs, and any immediate capital expenditures (CapEx) required to get the property operational (like replacing a roof immediately after purchase).
