Cash on Cash Return vs Yield on Cost: What Each One Measures on the Same Deal

Cash on cash return vs yield on cost comes down to the denominator. Yield on cost divides net operating income by everything the deal cost. Cash on cash return divides the cash flow left after the mortgage by the cash you actually put in. On the $500,000 rental used across this site, yield on cost runs about 7.9% and cash on cash return about 6.3%.

Yield on cost grades the finished asset. Cash on cash return grades your position in it.

The two formulas

Yield on cost = stabilized net operating income / total project cost

Cash on cash return = (net operating income minus annual debt service) / cash invested

Both begin with net operating income: collected rent minus operating expenses, before any loan payment. Then they split.

Yield on cost leaves the loan out and divides by the full cost of getting the property leased and stabilized. That means purchase price, rehab, closing costs and any carrying costs during the work.

Cash on cash return subtracts the loan payments and divides by your own money. Change the financing and it moves. Yield on cost does not move, because the loan was never in it.

Return on cost is the same measure under a different name, and most investors use the two terms interchangeably. The real variable is what went into the cost number, so ask before you compare two quoted figures.

The same deal measured both ways

Take the standard example: a $500,000 rental renting for $5,200 a month, $10,000 of rehab, $6,000 of property taxes and $2,400 of insurance. Net operating income is $40,210. Closing costs add $15,000, so all-in cost is $525,000.

Measure	Top of the fraction	Bottom of the fraction	Result
Cap rate	NOI $40,210	Price $500,000	8.0%
Yield on cost	NOI $40,210	Price plus rehab, $510,000	7.9%
Yield on cost, all-in	NOI $40,210	Price, rehab and closing, $525,000	7.7%
Cash on cash, all cash	Cash flow $40,210	Cash invested $525,000	7.7%
Cash on cash, 25% down at 7.25%	Cash flow $9,512	Cash invested $150,000	6.3%

Three readings come out of that table.

Yield on cost lands below the capitalization rate because rehab sits in its denominator and not in the cap rate’s. Spend more to fix the place up and yield on cost falls while the cap rate stays at 8.0%.

Yield on cost on an all-in basis and the all-cash cash on cash return are the same number, 7.7%. That is not a coincidence. With no loan, cash flow is net operating income and cash invested is total cost, so the two formulas collapse into one.

The drop from 7.7% to 6.3% is the loan. The $375,000 mortgage at 7.25% costs $30,698 a year, more per borrowed dollar than the 8.0% cap rate pays, so borrowing pulls the return down on this deal. Cash on cash return vs cap rate works through that comparison in detail.

What yield on cost is actually for

Yield on cost exists to answer one question: does the work create value? You compare the stabilized yield on your total cost against the cap rate that finished, stabilized properties trade at in the same submarket.

At a 7.9% yield on cost, the rental earns more on your $510,000 than a buyer would likely accept on a purchase price. If comparable finished properties trade at a 7% cap rate, the stabilized net operating income of $40,210 supports roughly $574,000 of value against $510,000 spent. The gap is the point of the exercise.

Market cap rates vary by metro, property type and condition, and they come from recent comparable sales rather than a formula, so take them from local sales data, a broker or an appraisal. The Wikipedia entry on capitalization rate covers the definition.

There is no universal spread you have to hit. Wider is safer, because the spread is what absorbs cost overruns and a softer exit cap rate later.

Overruns hit the two numbers differently

Keep the same rental and spend $20,000 on rehab instead of $10,000.

Yield on cost goes from 7.9% to 7.7%, a drop of about 0.15 points.

Cash on cash return at 25% down goes from 6.3% to 5.9%, a drop of about 0.40 points. The extra $10,000 comes out of your pocket, so your denominator is $160,000 instead of $150,000 while the cash flow stays at $9,512.

The same overrun moves your return roughly two and a half times as far as it moves the project’s. That is the practical case for tracking both numbers: yield on cost says whether the deal still pencils, cash on cash return says whether your own money still earns what you planned.

Cash yield, ROCE and the rest of the family

Cash yield usually means cash on cash return: annual cash distributions divided by cash invested. Some investors use it for the unlevered figure instead. Check whether a number is before or after debt service before you compare it to anything.

Return on capital employed, or ROCE, is a corporate ratio: operating profit divided by debt plus equity. Applied to a single rental it behaves much like yield on cost, since the denominator is the whole capital stack rather than your share of it. Return on assets is the closest term in the glossary.

Where both fall short

Both are single-year snapshots, and neither handles timing.

During a rehab, yield on cost describes a stabilized year that has not happened yet, while real cash flow may be negative for months. The project yield looks fine on paper and your bank account disagrees.

Neither counts appreciation, principal paydown or the eventual sale. Internal rate of return (IRR) brings timing into it, and payback period answers the simpler version: how long until the cash comes back. The limitations of cash on cash return are worth reading next to this page.

Run both on your own numbers

The cash on cash return calculator on the home page shows the financed return, the all-cash return and the cap rate on every run, so the project side and your side sit next to each other. Put the rehab in the repairs field and the all-cash figure is your all-in yield on cost. The simple tab takes cash flow and cash invested directly, so $12,000 of annual cash flow on $150,000 invested returns 8%.
