Plan the project before the project plans you.

Budget, build-vs-buy, remodel-vs-move, ADU payback, financing, labor burden and overrun tools built around assumptions you can see and change.

Planning decision

Garage Conversion vs Addition Calculator

Compare the estimated cost per added living square foot of converting a garage versus building a new addition using your own cost assumptions.

Planning decision

DIY vs Contractor Calculator

Compare a contractor quote with DIY materials, tools, your time value and an expected redo-risk cost to see the risk-adjusted difference.

Planning decision

Contractor Labor Burden Calculator

Calculate a loaded labor cost per productive hour from wage, payroll burden, workers comp, benefits and nonproductive paid time, then estimate a billable rate for a target gross margin.

Planning decision

Home Addition Value Gap Calculator

Compare a home addition’s project cost with your own before-and-after home value estimates to see cost per added square foot, estimated value added and recapture.

Planning decision

Renovation Overrun Buffer Calculator

Build a transparent renovation reserve from expected change orders, unknown-condition allowance, price escalation and schedule carry costs.

Transparent scenario math

These tools do not supply local construction bids, code determinations or property appraisals. They make your own assumptions explicit so you can compare scenarios without hiding the math.
