# Water Damage Cost Calculator Tempe AZ | Water Damage Tempe > A free water damage cost calculator for Tempe, AZ, by water category. URL: https://waterdamagetempe.com/tools/water-damage-cost-calculator/ This interactive calculator (JavaScript required) takes affected square footage, water category, and how long water has been standing, and returns a real, sourced budget range. RESEARCH.md documents industry-standard bands of $3-4/sq ft for Category 1 (clean) water and $7-7.50/sq ft for Category 3 (black) water — the sourced basis for the formula. Category 2 (gray water) has no standard per-sq-ft rate in any source checked, so it is not priced here; the calculator routes gray-water jobs to a phone call instead. Choosing a standing time of 24-48+ hours adds a sourced Phoenix-specific mold remediation range ($927-$2,745, Angi) to the estimate, since mold can begin colonizing wet material in that window. The Tempe-specific average across all water damage restoration jobs is $2,251-$2,313 (Homeyou) — a useful sanity check against the calculator's output. This is a budgeting estimate, not a quote. A free on-site assessment gets you a real, written number.
