Stabilized NOI as a percentage of total project cost.
Return on Cost (also "Yield on Cost") is a property's stabilized NOI divided by its total project cost — the development equivalent of cap rate. Where cap rate measures the yield on an existing asset at market value, return on cost measures the yield on the developer's actual all-in cost basis. The spread between return on cost and market cap rate is the development's equity creation.
Return on cost is the central metric for evaluating development and value-add deals. A development project costs $20M to build and is projected to produce $1.6M of stabilized NOI: 8.0% return on cost. Compare to market cap rate: if comparable stabilized properties trade at 6.0% cap rate, the development creates equity equal to (8% – 6%) / 6% = 33% value creation over total cost. That spread is the development's reason for existing.
The spread between return on cost and market cap rate drives the entire development business. Spreads under 100 bps are typically not worth the development risk and execution complexity. Spreads of 150–200 bps are workable. Spreads of 200+ bps (e.g., 8% YOC vs 6% market cap) are strong and attract serious capital. Spreads below 100 bps mean the developer is taking risk without commensurate return.
On value-add deals (vs ground-up), return on cost measures the post-renovation yield against all-in cost (acquisition + capex + carry). A property bought for $4M with $800k of capex and a projected $360k stabilized NOI: total cost $4.8M, return on cost 7.5%. Compare to current cap rate — the spread is the value-add's equity creation.
Return on cost is used at two points. During underwriting, it's the projected metric — what the developer expects to achieve. During execution, it's tracked vs. plan — actual costs vs. budget, actual NOI vs. pro forma. Deals that hit return on cost projections deliver target returns. Deals that miss (cost overruns, NOI shortfalls) compress the spread to market cap rate, often killing the deal's economics.
| Land | $1,800,000 |
| Hard costs | $12,500,000 |
| Soft costs + contingency + carry | $3,200,000 |
| Total project cost | $17,500,000 |
| Projected stabilized NOI | $1,400,000 |
| Return on Cost = $1,400,000 ÷ $17,500,000 | 8.0% |
| Market cap rate (comparable stabilized) | 6.25% |
| Spread | 175 bps |
| Implied value at completion | $22,400,000 |
| Equity creation | $4,900,000 (28% of cost) |
Stabilized NOI divided by total project cost. The development equivalent of cap rate — measures yield on the developer's actual cost basis rather than market value.
Cap rate uses market value as the denominator. Return on cost uses total project cost. The spread between them is the equity created through development or value-add.
150–200 bps over market cap rate is workable. 200+ bps is strong. Under 100 bps typically doesn't justify the development risk — at that point, buying stabilized at market is usually a better risk-adjusted bet.
It quantifies the value-creation thesis. A developer expects to build at 8% return on cost into a 6% market cap rate environment — the 200 bp spread creates equity at completion. Without that spread, the development isn't worth the execution risk.
Yes — total project cost includes the developer fee (typically 3–5% of total cost). The fee is part of what the development must yield over to be viable.
