Collections Calc

Estimate how many containers you may need to finish a collection before committing Coal, Doubloons, Community Tokens, or time to the grind. Calc is short for calculator; I'm just using slang guys.

About & Quick Start How to use the calculator and read the estimate

Collections Calc

Estimate before you buy

This free, unofficial World of Warships collection calculator runs a Monte Carlo simulation to estimate how many containers a collection may take. It accounts for your current progress, duplicate exchange rate, saved collection tokens, and optional container cost.

Quick Start

  1. Search for a known collection, or enter its size and duplicate rate manually.
  2. Enter the elements, collection tokens, and duplicate progress you already have.
  3. Set the container details and optional cost, then choose Calculate Estimate.
  4. Use the expected range as a planning guide and acquire containers gradually.

Reading the Range

Typical 50th percentile Half of simulated players finish by this point.
Conservative 80th percentile A higher planning target for less favorable luck.
How the estimate works: The calculator runs 500,000 simulated collection completions and assumes collection tokens are saved until enough have accumulated to finish the remaining collection. Container drops are random, so actual results can still fall outside the estimate.
Plan with the estimate, not against RNG. These values are forecasting tools, not guarantees. Acquire containers gradually when possible to avoid over-purchasing. The calculator assumes you will save collection tokens until there are enough to finish the collection.
