What Counts in Cash on Cash Return and What Gets Left Out
Cash on cash return includes the full mortgage payment, interest and principal. It leaves out appreciation, sale proceeds and tax savings. A line by line guide.
By the CashOnCashReturnCalculator.com team
Cash on cash return includes the mortgage. It takes into account the full debt service, interest and principal in one lump. It does not include appreciation. It does not include sale proceeds. Every dollar that counts has one thing in common: it actually moved, in or out of your account, because you own the property this year.
That is the whole inclusion rule. The formula guide teaches the steps; this one applies the rule line by line, because the steps are rarely where people go wrong. The math is easy. Deciding which dollars belong in each half is where deals get mispriced.
The two halves: cash into your pocket, cash out of it
The top half is a year of cash flow: rent you actually collect, minus the cost of running the place, minus the loan payment. The bottom half is the cash you put in to get the property working: down payment, closing costs, and repairs before the first tenant.
Two questions settle almost every item.
- Did real money move? Equity, market value and paper losses do not count.
- Did it move this year, and will it move again next year? Cash flow is the recurring half. One-time money belongs in the bottom half or nowhere.
Mortgage payments: why interest and principal both count
Yes, cash on cash return includes debt service, and it includes the principal part of the payment. People expect principal to be excluded because it buys equity instead of vanishing. Both things are true at once. It buys equity, and it leaves your checking account, so the cash flow half subtracts it.
Take the standard deal. A $500,000 rental, 25% down, $15,000 of closing costs and $10,000 of paint and carpet, so $150,000 of cash invested. It rents for $5,200 a month. After 5% vacancy you collect $59,280. Property taxes are $6,000, insurance is $2,400, and 18% of collected rent, about $10,670, covers maintenance, reserves and management. Net operating income is $40,210.
The $375,000 loan at 7.25% over 30 years costs $2,558 a month, or $30,698 a year. All of it comes out. Cash flow is $9,512, and the return is $9,512 divided by $150,000, or 6.3%.
About $3,630 of that first year of payments went to principal. Add it back and cash flow reads $13,142, so the return reads 8.8%. That is a real figure and a useful one, but it is not cash on cash return. It is a different rate of return, one that mixes cash with equity. Mixing the two is the quickest way to talk yourself into a deal.
Appreciation sits outside the number entirely
No, cash on cash return does not include appreciation. If that $500,000 property gains 3% in a year, you picked up $15,000 of capital appreciation and the return still reads 6.3%.
The exclusion is on purpose. Appreciation is a forecast until you sell or borrow against it, and it swings by market and by decade, so there is no honest single figure to plug in. Your own market’s price history is a better guide than any national average. Cash on cash return stays with the part you can spend.
The loan balance falling, the property value rising, your equity growing: none of them appear either.
Sale proceeds, refinance cash and other one-offs
Sale proceeds are out. The number describes one year of owning a property, not the exit. A check at closing belongs to measures that run across the whole hold.
A cash-out refinance is the same kind of event. That money is not income, it is borrowed. What most investors do instead is rerun the return afterward, with the new payment in the cash flow half and only the cash still left in the deal on the bottom.
Other items that trip people up:
- Security deposits are not income. You are holding someone else’s money.
- An insurance payout after a storm is a one-off, and usually comes with a repair bill attached.
- Pet rent, parking and laundry income recur, so they count.
- Your own labor is not cash, so it counts for nothing here. Dropping management from expenses because you self-manage simply inflates the number.
Taxes and depreciation: why this is a pre-tax number
Cash on cash return is pre-tax. Property taxes and insurance count, because you write those checks. Income tax does not.
Depreciation is left out for the same reason appreciation is. Residential rental property is written off over 27.5 years under IRS rules, which can shelter part of the cash flow from tax. No money moves when you take the deduction, so the return does not budge. The benefit is real, it just lands on your tax return instead. Depreciation recapture works the same way in reverse: a cost at sale, outside the annual view.
A line by line checklist for your own deal
In the cash flow half: rent collected after vacancy, other recurring income, property taxes, insurance, HOA dues, any utilities you pay, management, maintenance, a capital reserve, and the entire mortgage payment.
In the cash invested half: down payment, closing costs, points and lender fees paid in cash, rehab and furnishing before the first tenant, and holding costs until rent starts.
Out of both halves: principal as a return, appreciation, sale proceeds, refinance proceeds, tax savings, depreciation, sweat equity, the loan balance and the current property value.
What the number tells you
It does one job well. It tells you how much cash comes back each year for each dollar you tied up, before tax, on this year’s numbers. $12,000 of annual cash flow on $150,000 invested is 8%, and that 8% can be set beside any other deal, a bond, or leaving the money where it is. What it will not tell you is how the next ten years go, which is covered in what cash on cash return cannot tell you.

Frequently asked questions
Does cash on cash return include the mortgage?
Yes. The full payment comes out of the cash flow half, interest and principal together, because all of it leaves your account. On the standard $500,000 example, the $375,000 loan at 7.25% costs $30,698 a year and every dollar is subtracted. Net operating income of $40,210 becomes $9,512 of cash flow, which is 6.3% on $150,000 invested.
Does cash on cash return include principal paydown as a return?
No on the return side, yes as a cost. Principal is part of the payment you subtract, and the equity it builds is not added back as income. In the first year of that loan about $3,630 goes to principal. Counting it as a return would lift the figure from 6.3% to 8.8% and turn a cash measure into an equity one.
Does cash on cash return include appreciation or sale proceeds?
Neither one. A 3% gain on a $500,000 property is $15,000 of equity, and the return still reads 6.3%. Sale proceeds belong to the exit, not to a single year of holding. Appreciation also depends on your market, so no single figure would be honest inside an annual number. Use total return or IRR when the sale matters.
Is cash on cash return before or after tax?
Before tax. Property taxes and insurance are counted because you write those checks. Income tax is not, and neither is the depreciation deduction, since no money moves when you claim it. That keeps the figure comparable between investors in different brackets. Your after-tax result will differ depending on your bracket and how your income is treated.
What does cash on cash return tell you?
It tells you how much cash the property sends back each year for every dollar of cash you put in, before tax, on this year's numbers. $12,000 of cash flow on $150,000 invested is 8%. That makes deals of very different sizes comparable. It says nothing about value, equity or what happens when you sell.
