Yield on Cost (YoC)
Yield on Cost (YoC) is a return-on-cost metric equal to a property's stabilized net operating income (NOI) divided by its total project cost — the all-in acquisition or development basis plus capital improvements. It answers "what unleveraged yield will this deal produce once it's fully built out and leased up?"
Formula
Yield on Cost = Stabilized NOI ÷ Total Project Cost
How Yield on Cost Is Used
Yield on Cost is the core underwriting metric for value-add and ground-up development deals, where the cap rate at purchase is meaningless because in-place income is depressed or nonexistent. Instead of dividing income by market value, YoC divides projected stabilized NOI by everything you actually spent to reach stabilization. Analysts then compare that yield to the prevailing exit (market) cap rate for the finished asset; the difference is the 'development spread' or 'yield-on-cost premium.'
- •Total project cost includes purchase price (or land basis), hard costs, soft costs, financing/carry costs, leasing costs, and closing costs — the full capitalized basis.
- •Stabilized NOI is the forward NOI once the business plan is executed: renovations complete, units re-leased at market rents, and occupancy at a normalized rate.
- •YoC is unlevered — it measures the asset's return on invested capital before any debt, so it is directly comparable to a cap rate.
- •A common rule of thumb: target a YoC that exceeds the exit cap rate by at least 100–150 basis points to justify the execution and construction risk.
Why the Development Spread Matters
The spread between Yield on Cost and the exit cap rate is where value creation lives. If you build to a 7.0% YoC and the finished product trades at a 5.5% market cap rate, you have manufactured value: capitalizing the same stabilized NOI at 5.5% produces a value well above your cost basis. That spread is the developer's or sponsor's margin for taking on entitlement, construction, and lease-up risk. When the spread compresses toward zero — because construction costs rise or exit cap rates widen — the deal no longer compensates for its risk, even if the raw yield still looks acceptable.
Common Pitfalls and Nuances
YoC is only as honest as its two inputs, and both are frequently overstated. The most common error is understating total project cost by omitting carry, contingency, leasing commissions, or interest reserve — every dollar left out inflates the yield. The second is an aggressive stabilized NOI built on optimistic rent growth or an unrealistically low stabilized vacancy. Because YoC is a static, single-point metric, it also ignores the time value of money and the lease-up path — two deals with the same YoC can have very different IRRs depending on how long stabilization takes.
- •Distinguish 'untrended' YoC (today's rents) from 'trended' YoC (rents grown to stabilization) — trended figures look better but carry forecast risk.
- •Always pair YoC with a levered IRR and equity multiple; a strong yield on cost with a three-year lease-up can still produce a mediocre IRR.
- •Hold contingency and interest reserve inside total project cost, not off to the side, or the yield is artificially high.
Worked example
A sponsor buys a 100-unit value-add multifamily asset for $18,000,000 and budgets $4,000,000 in renovations, $500,000 in soft/financing costs, and $500,000 of interest carry and leasing costs — a total project cost of $23,000,000. After the renovation and re-leasing plan, stabilized NOI is projected at $1,610,000. Yield on Cost = $1,610,000 ÷ $23,000,000 = 7.0%. If comparable stabilized properties trade at a 5.5% exit cap rate, the deal carries a 150-basis-point development spread. Capitalizing the $1,610,000 NOI at 5.5% implies a stabilized value of roughly $29,300,000 — about $6.3M of value created over the $23M basis.
Frequently asked questions
- What is a good Yield on Cost (YoC)?
- There is no universal number — 'good' is defined relative to the exit cap rate, not in absolute terms. Most developers and value-add sponsors want a YoC that exceeds the market cap rate for the finished asset by at least 100–150 basis points (the development spread) to compensate for construction and lease-up risk. In a 5.5% cap-rate market, that means targeting roughly a 6.5–7.0%+ yield on cost; a spread under ~75 bps generally means the deal isn't paying you enough for the risk.
- What is the difference between Yield on Cost and Cap Rate?
- Both divide NOI by a denominator, but the denominator differs. Cap rate uses current market value (NOI ÷ value), so it reflects what a buyer pays today. Yield on Cost uses your total project cost (stabilized NOI ÷ all-in basis), so it reflects the return you build to after executing a renovation or development plan. On a stabilized, no-value-add acquisition the two converge; on a value-add or ground-up deal, YoC is the metric that captures the value you create.
- Should Yield on Cost use trended or untrended rents?
- Both are used, and you should know which you're looking at. Untrended YoC uses today's market rents for the stabilized NOI, giving a conservative, defensible yield. Trended YoC grows rents to the projected stabilization date, which raises the yield but embeds forecast risk. Institutional investment committees typically underwrite to untrended YoC as the downside anchor and view trended YoC as the upside case.
