Formula Breakdown

Annual rent = monthly x 12Turn the monthly rent into a yearly figure first. Rent of $1,800 per month becomes $1,800 × 12 = $21,600 of gross scheduled rent.
Vacancy loss = rent x rateSubtract expected empty time. A 6% vacancy on $21,600 removes $21,600 × 0.06 = $1,296, leaving $20,304 collected.
NOI = collected rent − costsNet operating income is collected rent minus tax, insurance, maintenance, HOA and management. It excludes any mortgage payment.
Gross yield = rent / priceGross rental yield is annual rent divided by purchase price, times 100. $21,600 / $250,000 = 8.64%.
Net yield = NOI / total costNet rental yield is NOI divided by price plus closing costs, times 100. It shows the true income return after expenses.
Cap rate = NOI / priceCap rate divides NOI by purchase price only, so it compares deals on a clean price basis without buying costs.
GRM = price / annual rentThe gross rent multiplier is price divided by annual rent. $250,000 / $21,600 = 11.6, a quick relative value gauge.

💡Yield Rules of Thumb

The 1% rule: Aim for monthly rent of at least 1% of the purchase price. A $200,000 property should rent for about $2,000 per month to signal solid gross yield near 12%. Falling well under 1% usually means the deal leans on appreciation rather than income, so gross yield alone can look thin even before expenses.
Net beats gross, and mind the 50% rule: Gross yield ignores every cost, so it always flatters a deal. Net yield subtracts tax, insurance, maintenance, management and vacancy, which often consume close to 50% of rent. If gross yield is 8.6% and half of rent goes to expenses plus a 6% vacancy, net yield lands near 5%, and that lower number is what you actually keep.

What’s my potential rental yield? That’s the first (and most important) question on every property investor’s mind: How much will I earn from owning this building compared to what I paid for it? By expressing rent as a percentage of price, we get rental yield which lets us compare an inexpensive Midwest duplex to an overpriced coastal condo on even footing.

With simple inputs, the rental yield calculator calculates gross rental yield, net rental yield, annual net operating income, cap rate, and gross rent multiplier. In other words, you’ll be able to quickly assess a deal without firing up your spreadsheet. It ignores taxes, financing, and mortgage. This is critical because those depend on your personal bank loan terms. The rental yield calculator measure the asset itself.

How to Use the Rental Yield Calculator

The easiest metric, and the one most listings will initially cite, is gross rental yield. Take the annual rent, divide by the purchase price, then multiply by one hundred. If your property rents for $1,800 per month, that’s $21,600 annually. Against a purchase price of $250,000, that’s a gross yield of 8.64 percent. Useful (fast) and always looks better in real life.

Gross yield ignores all costs. It’s useful because it provides a quick screening tool, two properties could have the same gross yield yet produce wildly different amounts of profit when you count repairs, insurance, and taxes. Agents love quoting this headline number. It doesn’t push you any further. That is why the calculator won’t let you stop here.

But this is the number that matters: Net rental yield. Here’s how the calculator begins: It assumes your annual rent. Then it takes out a vacancy allowance (to account for months when the house sits vacant). Next, it deducts your property management fee; HOA dues; maintenance expense; insurance; and property tax. This leaves you with net operating income.

You divide that income by the sum of all costs… Including the purchase price plus closing costs. And voila! This is your net yield. With our $250,000 illustration (assuming about $9,000 in annual expense, and a six percent vacancy rate), your net yield will come in at around five percent. The spread between gross, 8.64 percent (and net)… Five, says everything you need to know about operating costs, the area where rookie landlords can be taken aback by the realties of being a landlord.

For serious real estate analysis, we’re talking about Net Operating Income, or NOI. This represents the annual income produced by the property before the payment on any loan: this is an assessment of the property itself, not of how you finance it. From there, you simply divide the NOI by the purchase price, then multiply by one hundred and you’ve got your cap rate in hand! Cap rate is common language of both residential and commercial investing. You’ll say that a deal trades at a five cap or a seven cap and people will know what you mean right away.

The calculator tells you both the monthly and annual amount of NOI. In other words, how much cash does the property spit out before debt service? A simple relative value indicator (which doesn’t replace net yield) is the gross rent multiplier, or GRM: divide the purchase price by the yearly rent. If the price = roughly eleven-and-a-half years of rent, then its GRM = 11.6. The lower the multiplier, the better, typically meaning strong relative income vs. Price. High multipliers (common in expensive appreciation markets) tell you you’re paying a higher price per dollar of rent. You’ll see GRM used as a shorthand when scanning lots of listings; it’s a good rule of thumb (though not a replacement) if you’re looking for one number to sort them by.

New investors get tripped up by two types of inputs more than anything else: Management, and Vacancy. Property management typically runs eight to 10 percent of collected rent. Five to eight percent for vacancy, one vacant month per year, is realistic as well. It’s 8.3 percent of the year.

The 50 percent rule has served seasoned investors well. They notice that after averaging in capital items, turnover, repairs, and other costs, operating expenses; not including the mortgage… Tend to eat up roughly half of gross rent over the long term. The calculator won’t compute the numbers if your estimated expenses are significantly less than half, but it pays to ask yourself what you may have forgot… Optimism isn’t a strategy.

To place results into context, the tool displays them alongside some tables below the calculator. The market table gives an idea that gross yields are normaly around three to five percent in top coastal cities (and double digit in cheaper rural and Midwest markets). There’s also a quality band table which rates net yields… Ranging from poor (7%), along with a suggested action for each.

An expense table breaks out the 50 percent rule line by line to show how taxes, insurance, maintenance, management, and vacancy take a portion of your rent. There’s also a cap rate table that shows normal cap rates for different asset classes, from short term rentals to Class A apartments. There is also a wide comparison grid that shows how numbers like gross yield, net yield, cap rate, and GRM change as price increases relative to rent. They’re all benchmarking tools to understand whether your results are good…or just plain lucky.

To play around with the math, there are ten presets that load realistic deals. Try one of these: a $250k condo renting for $1,800 per month, a $400k single family home renting for $2,600, a $120k turnkey rental bringing in $1,150 per month, or a high-cost $700k property cash-flowing for $3,500. See how the yields drop with price increases. Every preset populates all fields and refreshes automatically, and you can change any parameter to run your own scenario. Results update in real time.

The breakdown shows each deduction from rent down to NOI. The print button gives you a clean summary to save to your files. It’s all about getting comfortable with the numbers before putting real money behind it.

There’s more than one lens through which to view yields: Yield is just one, but it’s a strong one because it strips a deal down to income per dollar of price. Thin net yield + a high gross yield = watch out! Someone is eating your return. A solid net yield and a modest gross yield mean it is possibly well run and in a stable area. Rent/offer price that hits your target return.

The Rental Yield Calculator puts Gross yield, Net yield, Cap Rate, NOI, and GRM side by side. This lets you compare properties fairly, spot deals that look good but aren’t, and set your offer or rent price based on your target return. Start with a preset, enter your own numbers, and let the percentage do the talking, because the building will work for you…only if you understand exactly how hard it’s working for you.
