Clash of Clans Upgrade Calculator

How This Clash of Clans Upgrade Calculator Works

This Clash of Clans upgrade calculator estimates the Gold, Elixir, Dark Elixir, builder time, and Laboratory research time left to max your Home Village Town Hall — or to plan a full upgrade path through a higher target Town Hall. Because builders, the Laboratory, and the Pet House all run as separate, parallel queues, the calculator tracks each one independently instead of adding their durations together.

Enter your current Town Hall, roughly how far along each category is, your builder count, and any cost or time reductions — the calculator returns remaining resource totals, a calendar-time estimate for each queue, and the single track that's actually holding your account back.

Why Parallel Queues Matter

Village progress splits into three independent queues. The calculator never adds their durations together — it takes the longest one, because that is the queue actually determining how long you'll wait.

Builder days and Laboratory days cannot simply be added together because they run at the same time, not one after another. If your builders need 40 days and your Laboratory needs 60 days, the true time to max is 60 days — not 100 — because both queues are running in parallel throughout that period. Adding more builders shortens the builder queue but has no effect on Laboratory or Pet House time, since those are single, independent queues regardless of how many builders you own.

Builder Time vs Laboratory Time

This is why the calculator reports a separate calendar duration for each queue and a bottleneck label — the queue with the longest remaining duration is the one actually controlling your time to max, and it's frequently the Laboratory, not builders, at higher Town Halls.

Resource Totals: Gold, Elixir, Dark Elixir, and Walls

Buildings, Heroes, Laboratory research, and Pet House upgrades each draw from Gold, Elixir, or Dark Elixir depending on the category — the calculator sums exactly what each remaining upgrade actually costs. Walls are reported separately as a flexible budget rather than split into Gold and Elixir, because wall levels can be purchased with either currency and folding that choice into the main totals would double-count it.

The wall budget is never reduced by the generic cost reduction field, since a generic reduction percentage cannot be proven to apply to wall levels specifically.

Dataset Accuracy and Scope

Clash of Clans is a live-service game — Supercell regularly changes upgrade costs, durations, and maximum levels in balance updates. This calculator uses a reviewed, versioned snapshot rather than live scraping: TH18 July 2026 planning snapshot, last verified July 3, 2026. Category totals were reviewed against official Supercell release notes and cross-checked with community-maintained cumulative cost tables where Supercell does not publish a permanent all-level export.

This first release covers Home Village only. It excludes Builder Base, Clan Capital, Hero Equipment (which uses different currencies and progression rules), cosmetics, scenery, and event-only upgrades. Baseline estimates also exclude Books, Hammers, Runes, Potions, Gems, event boosts, Builder Apprentice, Lab Assistant, Goblin Builder, temporary helper events, and any idle time your queues actually sit empty.

Because the initial release does not include an item-by-item village editor, category progress is intentionally lightweight — an account with unevenly upgraded buildings within the same category can differ from this estimate.

Supported Town Hall Reference

Every Town Hall below is included in the current dataset snapshot, with the category tracks that apply at that level.
