Cost is computed from your analysis — not a flat fee.
The formula
cost = 10 + engine_credits × year_factor
year_factor = max(1.0, years / 5)
10
Base cost per run — location, configuration, export.
engine_credits
Each engine you enable adds credits by tier.
year_factor
Years of climate history scale engine cost. 1–5 years is free; 10 years doubles it.
A low-resolution run costs
credits per run — depending on engines enabled and years of climate history.
Typical feasibility run
10 + (2 + 2 + 2) × 1.0 = 16 credits
A 5-year study with Conduction, Latent / Crop ET, and Ventilation.
Full 10-year study
10 + (2 + 8 + 9) × 2.0 = 48 credits
Every engine enabled over 10 years (Metrics 2×1 + Physics 4×2 + Sizing 3×3, with Fan & Pad + Fog, no Chiller).
High-resolution runs (ORC-ARCH-lite, v1.2) are flat 500 credits — arriving as a separate premium tier.
If your question isn't here, get in touch.
A credit is the unit of cost for a single WDAT analysis run. Most runs fall between 10 and 30 credits — see the formula above for the exact cost.
Purchased credits don't expire while your account is active. Free monthly credits reset on the 1st of each month and don't roll over.
Your free tier refreshes on the 1st of each month with 180 credits. If you can't wait, buy a pack — purchased credits stack with your free balance.
