Cash-on-Cash Return Explained: Formula, Examples & What's Good

Cash-on-cash return is the metric that tells you how hard your money is actually working. Unlike cap rate, it accounts for the mortgage — so it measures the real cash yield you earn on the dollars you put into a deal.

If you put $50,000 down on a rental property and it generates $3,500 in annual cash flow after all expenses and the mortgage payment, your cash-on-cash return is 7%. That’s the number you compare against what your money could earn elsewhere.

The Cash-on-Cash Return Formula

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

Annual Pre-Tax Cash Flow is rent minus everything: operating expenses, vacancy, property management, and the full mortgage payment (PITI — principal, interest, taxes, insurance).

Total Cash Invested is all cash you actually spent to acquire the property: down payment, closing costs, any upfront repairs or staging, and initial reserves. Not the purchase price — the actual cash out of your pocket.

Step-by-Step Calculation

1. Calculate annual cash flow:

Line Item	Monthly	Annual
Gross Rental Income	$2,000	$24,000
Less: Vacancy (5%)	−$100	−$1,200
Less: Property Management (8%)	−$160	−$1,920
Less: Maintenance Reserve	−$150	−$1,800
Less: Insurance	−$100	−$1,200
Less: Property Taxes	−$250	−$3,000
Less: Mortgage (P&I)	−$970	−$11,640
Monthly Cash Flow	$270	$3,240

2. Calculate total cash invested:

Item	Amount
Down payment (20%)	$40,000
Closing costs	$4,200
Initial repairs	$2,500
Reserves (3 months)	$2,400
Total Cash Invested	$49,100

3. Calculate cash-on-cash return:

$3,240 ÷ $49,100 × 100 = 6.6%

Worked Examples

Example 1: Standard Long-Term Rental

• Purchase price: $185,000
• Down payment (25%): $46,250
• Closing costs: $4,800
• Total cash in: $51,050
• Monthly rent: $1,850
• Monthly expenses (all-in including mortgage): $1,565
• Monthly cash flow: $285 → $3,420/year
• Cash-on-Cash Return: $3,420 ÷ $51,050 = 6.7%

Example 2: Small Multifamily Duplex

• Purchase price: $310,000
• Down payment (25%): $77,500
• Closing costs + minor repairs: $8,200
• Total cash in: $85,700
• Combined monthly rent: $3,200
• Monthly expenses (all-in including mortgage): $2,625
• Monthly cash flow: $575 → $6,900/year
• Cash-on-Cash Return: $6,900 ÷ $85,700 = 8.1%

Example 3: High-Cost Market Condo

• Purchase price: $520,000
• Down payment (20%): $104,000
• Closing costs: $9,000
• Total cash in: $113,000
• Monthly rent: $3,200
• Monthly expenses (all-in including mortgage + HOA): $3,180
• Monthly cash flow: $20 → $240/year
• Cash-on-Cash Return: $240 ÷ $113,000 = 0.2%

The condo example illustrates a common scenario in expensive coastal markets: the cash flow is nearly zero, so investors are essentially betting entirely on appreciation.

Example 4: BRRRR Deal (Recycled Capital)

After a BRRRR refinance that returns most of your capital:

• Total cash left in deal after refinance: $12,000
• Annual cash flow: $2,400/year
• Cash-on-Cash Return: $2,400 ÷ $12,000 = 20%

When a BRRRR deal recycles most of your capital, the cash-on-cash return on remaining equity becomes very high — which is the appeal of the strategy.

What Is a Good Cash-on-Cash Return?

There’s no universal answer, but here are the benchmarks most investors use:

Cash-on-Cash Return	Interpretation
Below 4%	Thin; usually a bet on appreciation
4%–6%	Acceptable in appreciating markets
6%–8%	Solid; competitive with other investments
8%–12%	Strong; excellent for rentals
Above 12%	Exceptional; high risk or BRRRR/creative financing

Compare to your alternatives. If a stock index fund has returned 10% annually, a 5% cash-on-cash return only makes sense if you believe appreciation, equity paydown, and tax benefits make up the difference. They often do — but know what you’re getting.

Compare within your market. A 6% cash-on-cash return in a market where cap rates compress and appreciation runs 5%/year is very different from 6% in a flat market with no appreciation.

Cash-on-Cash Return vs. Cap Rate

These two metrics often confuse new investors. Here’s the key difference:

Cap rate ignores financing. It measures the property’s income yield at its value, independent of how you paid for it. Two investors who buy the same property — one all-cash, one with a mortgage — would calculate the same cap rate but different cash-on-cash returns.

Cash-on-cash includes the mortgage. It measures your actual cash return on your actual cash investment. Leverage (using a mortgage) typically amplifies cash-on-cash return when the cap rate exceeds the mortgage interest rate.

Example of leverage amplification:

• Property: $200,000 purchase price, $13,000 NOI (6.5% cap rate)
• All-cash: Cash-on-cash = 6.5% (same as cap rate)
• 25% down at 7.5% rate: Mortgage ≈ $10,560/year P&I; Cash flow = $13,000 − $10,560 = $2,440; Cash invested = $50,000 + $5,000 closing = $55,000; Cash-on-cash = $2,440 ÷ $55,000 = 4.4%

In this case, leverage reduced cash-on-cash return because the mortgage rate (7.5%) exceeded the cap rate (6.5%). This is called negative leverage — common in today’s higher-rate environment.

When the cap rate exceeds the mortgage rate (positive leverage), using a mortgage increases cash-on-cash return.

How to Improve Cash-on-Cash Return

Increase rent. The most direct lever. $100/month more rent = $1,200/year more cash flow.

Reduce vacancy. A month of vacancy at $2,000/month costs $2,000 in annual income. Screen tenants well, price competitively, and minimize turnover.

Reduce operating expenses. Self-manage (saves 8%–10%), shop insurance annually, negotiate service contracts.

Increase down payment (carefully). Counterintuitively, a larger down payment reduces the mortgage and increases cash flow — but it also increases total cash invested. The net effect on cash-on-cash depends on the specific numbers.

Reduce purchase price. Lower price = smaller loan = lower mortgage payment = higher cash flow. Negotiation, off-market deals, and BRRRR all help here.

Add units or income streams. ADUs, storage rental, parking, coin laundry, and similar additions increase income without proportional expense growth.

What Cash-on-Cash Doesn’t Capture

Cash-on-cash is a snapshot of current cash yield. It misses several important components of total return:

• Appreciation. If the property increases in value 4%/year, that’s a $8,000 annual gain on a $200,000 property — often larger than the cash flow itself.
• Equity paydown. Every mortgage payment builds equity. In year 1 of a 30-year mortgage, a small portion goes to principal; by year 10, it’s significant.
• Tax benefits. Depreciation deductions can shelter rental income, effectively increasing after-tax cash-on-cash return.
• Rent growth. As rents increase over time, cash flow grows — but cash-on-cash is calculated at today’s numbers.

For a complete picture, combine cash-on-cash with total ROI or IRR analysis. Cash-on-cash answers: “What am I earning today?” Total ROI answers: “What will this investment return over time?”
