Shell Delivery Vs Turnkey Cost Calculator
Delivery condition drives landlord cost. This calculator compares options.
Turnkey vs warm shell premium
$1,350,000
Turnkey premium in years of rent
2.5
Warm shell total
$2,250,000
How the math works
Turnkey premium = (turnkey − warm shell) × SF. Years of rent = premium / annual rent.
15k × ($240 − $150) = $1.35M turnkey premium. Annual rent $540k. Premium = 2.5 years rent — significant concession landlord recoups over term.

How this calculator works
What this page estimates
This Shell Delivery Vs Turnkey Cost Calculator is built to give a quick, browser-based estimate for shell delivery vs turnkey cost. Delivery condition drives landlord cost. This calculator compares options. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the shell delivery vs turnkey cost result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this shell delivery vs turnkey cost estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions
Delivery options defined?
Cold shell: bare slab, exterior envelope, utility stubs to suite. Warm shell: plus HVAC stubs, restrooms, basic electrical panel, fire-life-safety. Turnkey: full finished space including office build-out per plan, ready for tenant move-in. Each step materially increases landlord spend.
Typical costs?
Cold shell: $80-150/SF new construction. Warm shell: $120-180/SF. Turnkey: $180-350/SF depending on finish level and program complexity. Retail turnkey (restaurant): $250-500/SF. Office high-rise turnkey: $200-300/SF for standard build-out.
How to negotiate?
Landlord pays shell cost anyway for vacant space. Turnkey trades for longer term, higher rent, or lower TI. Warm shell + TI allowance typically preferred by landlord (tenant manages build-out risk). Full turnkey preferred by tenants with low capital.
