Pool Evaporation / Cover Loss Calculator

Estimate planning loss from evaporation, splash-out, and water features, then compare uncovered and cover-use scenarios. This is not a leak diagnosis and it does not replace a bucket test.

Limitations

Evaporation changes with wind, humidity, sun, and temperature.
Autofill can hide a leak, so unexplained loss still needs a bucket test or leak detection.
Safety-cover water is separate and not modeled as stored pool water.
This is a planning estimate, not a leak proof or service quote.
