How the calculation works
Total = (square feet × cost per square foot + bathroom + egress + permits) × (1 + contingency rate).
Every rate, percentage, cost and value assumption shown in the calculator can be changed. Results are scenario math based on your inputs, not quotes, appraisals, code determinations or predictions.
Questions people ask
Why separate bathroom and egress costs?
Those items can be unusually expensive relative to open finished space, so separating them makes the estimate easier to audit.
Does this determine whether my basement is legal living space?
No. It is a budget calculator, not a code-compliance tool.
