How the math works

Core formulas investors care about

Total project costLand + hard costs + soft costs + contingency + carry
Project profitProjected sale price - total development cost
Project marginProject profit / projected sale price

Why it matters

What to verify before you trust the answer

New construction deals are sensitive to cost drift, draw timing, rate changes, appraisal risk, absorption, and exit price. A strong model keeps contingency honest before the build starts.

What DealCalc surfaces

Land basis, hard costs, soft costs, and contingency
Construction debt, loan-to-cost, and interest carry
Total project cost and cash required
Projected sale price, project profit, and margin

Why investors use it

New construction underwriting needs more than a simple rehab calculator. DealCalc keeps the development stack, cash need, and exit margin in one investor-ready view.

Common mistakes

Underfunding contingency and treating it like extra profit.
Ignoring draw timing, interest carry, permits, utilities, and soft costs.
Using an exit price that does not match the finished product or local absorption.

Common questions

What does a new construction calculator show?

It shows the development cost stack, cash required, projected sale price, project profit, and margin so you can decide whether the build has enough room.

Is this the same as a rehab calculator?

No. Rehab calculators focus on renovation scope. New construction needs land basis, hard costs, soft costs, contingency, construction debt, and build-period carry.

Can I share a new construction report?

Yes. DealCalc can turn the underwriting into an investor-ready report with profit, cash required, assumptions, risks, and deal breakdown.
