Rental Yield Calculator
Evaluate rental property investment yields.
Formula
Gross = Rent/Value × 100
Example
$24K rent on $400K property, $6K expenses → 6% gross, 4.5% net.
Understanding the Rental Yield
Real estate calculators have a unique feature: they are best used as screening tools. If the rental yield number does not make sense in your market, skip the deal entirely; do not waste time on deeper diligence.
How it actually works
Evaluate rental property investment yields.
The formula is straightforward arithmetic once the inputs are correct; the value of the calculator is in handling the algebraic manipulation reliably and removing transcription errors. Plug in your specific inputs above and the result appears as you type, so you can immediately see how each variable affects the answer.
What the numbers really say
A $250,000 rental at 7% cap rate produces $17,500 NOI annually. After mortgage payments ($1,200/month on a $200K loan at 6.5%), the cash flow is just $3,100/year - a 6.2% cash-on-cash return on the $50K down payment. Looks fine. But add 8% vacancy and 1% capex reserves and the cash flow drops to $1,500. The cap rate looked attractive; the cash flow tells the truer story.
The deeper context most users miss
Real estate calculations have one feature that distinguishes them from other investment math: liquidity. Stocks and bonds can be converted to cash within days at predictable prices. Real estate often takes months and the realized price can swing 10-20% from the listed value depending on market conditions. The cap rate calculator might say a property generates 8% returns, but if you need the capital back urgently, the bid-ask spread on real estate can easily erase a year or more of those returns. This is why even excellent rental property analysis includes a cash reserve assumption - typically 6-12 months of expenses - that the equivalent stock investor would not need.
What people get wrong
- Underestimating capex reserves. Roofs, HVAC, and water heaters all fail eventually. Setting aside 8-15% of rents for big-ticket repairs prevents the deal from blowing up when something breaks.
- Using gross rent instead of NOI. Net Operating Income subtracts vacancy, taxes, insurance, and operating expenses. Cap rates and ROIs based on gross rent are misleadingly attractive.
- Trusting seller pro formas. Listing-agent projections almost always overstate income and understate expenses. Get T12 (trailing 12-month) actuals before making offers.
- Ignoring opportunity cost. The down-payment cash could have earned market returns elsewhere. Only count appreciation gains beyond what those alternatives would have produced.
When this calculator helps most
The rental yield calculator is most useful when you are making a real decision - comparing options, sizing a commitment, sanity-checking a quote, or planning ahead. The output is precise to your inputs; the inputs themselves are the place to slow down. Spend extra time on the assumptions you are making about rate, term, timing, or context-specific variables - those swing the answer far more than the formula's arithmetic does. A 5% change in the input often produces a 10-20% change in the output, which means small input errors compound into large output errors.
Where the math comes from
Real estate investment math draws from NAREIT (National Association of Real Estate Investment Trusts), the Appraisal Institute's standards, and BiggerPockets community-validated frameworks. For commercial property, ARGUS Enterprise valuation is the industry standard.
Questions and answers
What is a good cap rate?
Depends entirely on market. Class A urban: 4-6%. Class B suburban: 6-9%. Class C tertiary markets: 9-12%+. Higher cap rate compensates for higher risk - vacancy, tenant quality, location. Compare to local market norms.
Should I include my time as a cost?
For investment-quality analysis, yes - value your time at minimum wage equivalent for managing tenants, dealing with repairs, etc. For comparing to professional management (typically 8-12% of rents), this lets you decide whether self-management is worth it.
How does leverage affect returns?
Leverage amplifies both gains and losses. A 25% down payment with 4% appreciation produces 16% gain on equity (4% / 0.25). The same drop produces 16% loss. Cash flow must cover debt service in down markets.
What about tax benefits?
Depreciation is the biggest - typically 27.5 years straight-line on the building portion (not land). 1031 exchanges defer capital gains. Mortgage interest is deductible against rental income. Talk to a CPA familiar with real estate before structuring.
Should I buy turnkey or BRRRR?
Turnkey is cleaner - you pay closer to market price for a finished property. BRRRR (Buy, Rehab, Rent, Refinance, Repeat) requires more work and risk but builds equity faster if executed well. Pick based on your skill set and time.
