Yield on cost divides stabilized NOI by total project cost. How it differs from a cap rate, which costs get left out, and how to tell if a project pencils.

Every development conversation eventually reaches the same question: does it pencil? The shorthand answer is yield on cost. It is a simple ratio, and in my experience it is also one of the easiest numbers in real estate to misuse.
What is yield on cost in real estate development?
Yield on cost is stabilized net operating income divided by total project cost. Total cost includes land, hard costs and soft costs: design, engineering, permits, legal, financing costs during construction, leasing commissions and a contingency. The result tells you what return the finished project produces on what it actually cost to deliver.

Yield on cost = stabilized NOI ÷ total project cost. The spread over the exit cap rate is the margin that pays for the risk of building. The example figures are illustrative, not the terms of any property.

A cap rate is the same ratio applied to a market price instead of a cost: NOI divided by what a buyer would pay for the stabilized property. Yield on cost measures what you built; the cap rate measures what the market would pay for it. The gap between the two is the development spread, and it is the reward for taking on entitlement, construction and lease-up risk.
Andrew Danner explains how he reads a cap rate on a small neighborhood center. I will not quote a market cap rate here. It moves with interest rates, tenant credit and the specific property, and any number I gave would be stale or wrong for your deal.
The other half of the spread: what the market pays.
Yield on cost tells you what you built. The cap rate tells you what someone will pay for it. Development lives in the gap.
How big should the development spread be?
Large enough to pay for the risk you are taking. A project with entitlements in hand, utilities confirmed and leases signed carries less risk than one still waiting on a rezoning and a sewer extension. I set the spread I require before I run the numbers, so I am not tempted to argue myself into a thin one after the spreadsheet is built.
The spread is also not a promise. It is a measure of cushion. If costs run over or lease-up runs long, the cushion is what absorbs it. A thin spread leaves no room for the ordinary friction of a real project: a permit that takes an extra review cycle, a bid that comes in high, a tenant that needs one more month to open.
What costs get left out of a yield-on-cost calculation?
- Leasing commissions for the initial lease-up.
- Tenant improvement allowances and landlord work.
- Interest and loan fees during construction and lease-up.
- Free rent periods before stabilized income begins.
- Utility extensions, off-site road work and impact fees.
- Legal, title, survey, environmental and permitting costs.
- A contingency that is real, not a rounding figure.
Each missing line inflates the yield. The due-diligence checklist I use on pad sites is where many of these costs first appear, which is why I run diligence and the pro forma side by side rather than one after the other.
Why is stabilized NOI the hardest number to get right?
Because it is a forecast. Stabilized NOI assumes leases signed, rent commenced, and vacancy and expenses at normal levels. My colleague Ben Nelson's NOI-first approach is the right discipline: build the income line from actual leases and realistic assumptions, subtract real operating expenses, and only then divide by anything.
In a triple-net center, many operating expenses are recovered from tenants through CAM, taxes and insurance charges. That helps, but vacant suites do not reimburse anything, so the owner carries their share until they lease.
How does lease-up affect a project that pencils on paper?
Time is a cost. Every month a suite sits empty after completion is a month of carrying costs with no income from it. Signed leases with clear rent commencement dates turn a forecast into something a lender and an investor can rely on. That is one reason committed tenants matter so much in a new center.
How should you test a yield-on-cost estimate before relying on it?
Run it more than once. I change one input at a time and watch what happens to the yield: hard cost up by a hypothetical tenth, lease-up longer by a few months, rent on the last suite lower than planned. If a single modest change wipes out the spread, the project depends on everything going right, and that is worth knowing before the first check is written. I also compare the cost lines against bids and provider letters rather than estimates wherever the diligence work has produced them. A yield built on documents deserves more confidence than one built on assumptions, and the difference should show up in the spread you require.

How does this look at The Shops at Smithville?
The Shops at Smithville on U.S. 169 is 30,150 SF, with 18,680 SF available. Committed tenants include a pizza shop, AT&T, a nail salon, an HVAC company and an accountant. The remaining spaces are Suite 400 (1,400 SF), Suite 500 (2,100 SF), Suite 600 (5,180 SF) and the standalone 14901 South Building (10,000 SF). Each lease signed moves the project from forecast toward stabilized income.
For tenants, that matters in a practical way. An owner focused on lease-up has reasons to work through build-out, timing and structure with a tenant who is ready to commit. Brokers representing tenants can find suite details and contact information on the brokers page.

Questions people ask
How do you calculate yield on cost?
Divide the project's stabilized annual net operating income by its total cost. Total cost should include land, hard construction costs and soft costs such as design, permits, legal, financing during construction, leasing commissions, tenant improvements and a contingency. Leaving any of these out makes the yield look better than the project really is, which is the most common mistake I see.
What is the difference between yield on cost and cap rate?
Both divide NOI by a value. Yield on cost uses what the project cost to build; a cap rate uses what a buyer would pay for the stabilized property. When yield on cost is higher than the cap rate the market would apply, the difference is the development spread, which compensates the developer for entitlement, construction and lease-up risk.
What does it mean when a project pencils?
It means the numbers support going ahead: the expected yield on cost clears the return the developer requires, with enough spread over the value of the finished property to absorb overruns and delays. It is a judgment based on forecasts, not a promise of any result, so the assumptions behind the NOI and the cost deserve as much scrutiny as the ratio.
Why does lease-up speed matter for yield on cost?
Because stabilized NOI only arrives once space is leased and rent has started. Until then, the owner carries debt service, taxes, insurance and the share of operating costs that vacant suites cannot reimburse. A longer lease-up adds those carrying costs to the project, which raises total cost and lowers the effective yield on what was spent.
