Murals Don't Cost Money.They Make It.
Developers allocate capital based on returns. The WXLLSPACE ROI Calculator translates a mural investment into the language your ownership group, lender, and investment committee already speak — NOI, cap rate, and asset value.

The Problem
Murals Have Been Sold as Art. Developers Buy Returns.
The reason most mural proposals stall at the ownership level isn't budget. It's framing. When a mural is presented as a branding expense, it competes with every other discretionary line item in the budget — and loses. When it's presented as a capital investment with a documented return, the conversation changes entirely.
The WXLLSPACE ROI Calculator exists to close that gap. It reframes murals from art expense to asset value driver — using the same financial methodology your team already applies to every other capital decision.

How murals have been framed
- Marketing expense
- Branding initiative
- Placemaking amenity
How developers should evaluate them
- Rent premium generator
- NOI increase driver
- Asset value multiplier
How It Works
Standard Cap Rate Methodology. Applied to Mural ROI.
Commercial property value is derived from income. The cap rate formula — Property Value = NOI / Cap Rate — means that any increase in net operating income creates a proportional and immediate increase in asset value. The calculator applies this to murals in three steps.
01
Rent premium → NOI increase
A mural that justifies a 3% rent premium on a 250-unit property at $2,100/month creates $63/unit/month in additional revenue. Multiplied across units and months, that becomes a meaningful NOI increase.
Rent Δ = Units × Monthly Rent × Premium %Annual NOI lift = Rent Δ × 12s is some text inside of a div block.
02
NOI increase → asset value
Once you have the NOI increase, the cap rate converts it directly into asset value. This is identical to how your lender, appraiser, and investment committee model every other income-producing improvement you make to the property.
Value Increase = NOI Increase / Cap Ratee.g. $158,400 / 0.055 = $2,880,000
03
Value increase → ROI multiple
The ROI multiple divides total value created by the mural investment cost. This gives you the number that answers the ownership question: for every dollar we put into this mural, how many dollars in property value does it create?
ROI Multiple = Property Value Increase / Mural Coste.g. $4,352,727 / $180,000 = 24.2x
The Outputs
Four Numbers. One Ownership Deck.
The calculator returns four financial metrics — each mapped to a question your ownership group, lender, or investment committee will ask. Enter your property details once. Take four defensible numbers into every internal conversation.
Output 1
Annual Rent Impact
The additional annual rental revenue generated by the rent premium attributable to the mural installation and its placemaking effect on perceived unit quality.
Units × Rent × Premium % × 12
Output 2
Marketing Savings
Murals generate organic press coverage, social media impressions, and earned media that offset paid marketing spend. This output estimates the marketing budget reduction attributable to the installation.
Gross Revenue × Mktg Budget % × Savings %
Output 3
Property Value Increase
The increase in asset value created by the NOI improvement. Calculated using the standard cap rate formula — the same methodology your appraiser and lender use to value your property.
Annual Rent Impact / Cap Rate
Output 4
ROI Multiple
For every dollar invested in the mural, how many dollars in property value are created. This is the number that closes the capital allocation conversation — it turns a creative line item into an investment thesis.
Property Value Increase / Mural Cost
Scenario Presets
Conservative. Base. Aggressive. Run All Three.
The calculator includes three pre-built assumption sets that reflect the range of documented outcomes across commercial mural installations. Run all three before your ownership meeting — the spread tells you where your risk is and what upside looks like.
Conservative
Lower-bound. Defensible to skeptics.
Use this when presenting to a risk-averse ownership group or a lender who hasn't seen mural ROI data before. These numbers are easier to defend and harder to challenge.

Base
Industry benchmark. Most projects land here.
Reflects the typical outcome range for a well-executed commercial mural installation in a multifamily or mixed-use property. The default starting point for most planning conversations.

Reflects the upper range of outcomes from landmark installations, nationally recognized artists, or properties in high-visibility markets where the mural becomes a defining feature of the brand.

The Methodology
Where the Numbers Come From — and Why You Can Trust Them.
Two questions come up every time a developer shares this calculator internally. Both deserve a direct answer before the meeting, not during it.
Data Sources
"Where does the underlying data come from?"
- WXLLSPACE project outcomes
Post-completion data from commercial mural projects completed through the platform — developer-reported rent comparisons, lease-up velocity vs. market comps, and valuation changes documented at refinance or appraisal. - Third-party property research
Published academic and industry research on public art impact in commercial real estate — NOI impact in arts-district submarkets, tenant satisfaction in amenity-branded properties, and leasing velocity in markets with documented placemaking programs. - Cap rate formula (standard CRE)
Property Value = NOI / Cap Rate is the foundational commercial real estate valuation formula. The calculator applies no proprietary modifications — it uses the same model your appraiser and lender use.
Why Trust It
"Why should I trust a calculator built by the company selling the service?"
Fair question. Here is our answer.
- The calculator produces ranges, not point estimates. Ranges reflect genuine variance in real project outcomes — not manufactured precision.
- The disclaimer is prominent and specific. We do not hide the limitations of the model. Results are for planning purposes — not financial guarantees.
- The methodology is documented and linkable. Every benchmark has a source, published in WXLLSPACE Property Performance Research. Your team can verify the inputs independently.
- The cap rate formula is standard. We did not invent it. NOI / Cap Rate = Property Value is the same math your appraiser uses on every property in your portfolio.
