About Clash Calculator
Clash Calculator is built for players who want exact answers before spending ore, assigning a builder, or committing spells to an attack. The site combines calculators, upgrade planners, and public clan tools in one free web app.
Data sources
Equipment, building, upgrade-time, and damage values are derived from current Clash of Clans game data and checked for drift during updates. Player and clan lookups use public information returned by the official Clash of Clans API through the RoyaleAPI proxy. Village exports provide private level details that the public player API does not expose.
Building and upgrade datasets are also cross-checked against ClashKing sources. Public activity labels report only events observed by the site; they never claim access to a player's private login history.
Transparent assumptions
Scheduling tools model real start and finish timestamps, time zones, sleep windows, monthly Gold Pass resets, helpers, potions, and temporary Goblin lanes. Limitations are stated on each planner instead of being hidden behind an unexplained total.

Most calculators work locally in the browser. Sign-in is optional unless a feature needs verified ownership or cross-device storage. If a value looks outdated or a calculation needs correction, send the exact tool and input through the feedback form.
