How to Use This Calculator

  1. 1
    Purchase Price

    Enter the full purchase price you are paying the seller. This is the contract price before any financing adjustments, not including closing costs.

  2. 2
    Down Payment, Closing Costs & Rehab

    Enter your down payment amount in dollars (investment properties typically require 20–25% down). Add total closing costs (lender fees, title, escrow — usually 2–5% of purchase price) and any upfront renovation costs. All three are summed as your total cash invested, which is the denominator in the cash-on-cash return formula.

  3. 3
    Annual Gross Rental Income

    Enter total annual rent at 100% occupancy. For monthly rents, multiply by 12. Research comparable rentals to verify your figure is realistic for the market.

  4. 4
    Vacancy Rate

    Enter the expected percentage of time the property will be vacant each year. The national average is around 6–8%. Tight markets may run 3–5%; slower markets or short-term rentals may run higher. The calculator deducts vacancy loss from gross income to derive effective gross income.

  5. 5
    Annual Operating Expenses

    Enter total annual operating expenses excluding mortgage payments. Include property taxes, insurance, maintenance and repairs, property management fees, HOA dues, and any other recurring costs. A common rule of thumb is 35–50% of gross rent for residential rentals (the “50% rule”).

  6. 6
    Annual Mortgage Payments

    Enter your total annual principal and interest payments (P&I). This is what distinguishes cash-on-cash return from cap rate — the mortgage is included here. If you are buying all-cash, enter 0. To calculate your annual P&I, multiply your monthly mortgage payment by 12.

Formulas & Methodology

Cash on cash return measures the actual pre-tax cash yield on the dollars you personally invested — making it one of the most practical metrics for leveraged real estate investing.

Total Cash Invested

Total Cash Invested =
  Down Payment
  + Closing Costs
  + Rehab / Renovation Costs

This is the full capital you
deploy out-of-pocket to
acquire and prepare the asset.

Annual Pre-Tax Cash Flow

Pre-Tax Cash Flow =
  NOI
  − Annual Mortgage Payments (P+I)

NOI =
  Effective Gross Income
  − Operating Expenses

Cash on Cash Return

Cash on Cash Return =
  Annual Pre-Tax Cash Flow
  ÷ Total Cash Invested × 100%

Measures cash yield on
your personal invested
capital after debt service.

DSCR & GRM

DSCR = NOI ÷ Annual Debt Service
Lenders require ≥ 1.25 typically.
< 1.0 means income doesn't
cover the mortgage.

GRM = Purchase Price
      ÷ Annual Gross Rent
Lower GRM = better relative value.
