Crab Tycoon Shell Calculator
Interactive Crab Tycoon shell calculator — estimate hourly shell income by crab tier and count.
Plan your beach layout before spending cash on the wrong upgrade. This calculator estimates hourly shell output from your crab tier counts using the approximate doubling rule documented on the tier list. Use results to compare merge plans, offline logout value, and capacity expansions from the upgrade guide.
Shell Income Calculator
Enter how many crabs you own at each tier. The tool applies a base rate to Tier 1 and doubles effective output each tier step — matching merge math from how to merge crabs.

How the Math Works
Each tier doubles shell contribution versus the previous tier in this model. One Tier 3 crab equals four Tier 1 crabs in output — consistent with merge chains where two Tier 1 become one Tier 2, and two Tier 2 become one Tier 3. The calculator sums all entered crabs using Tier 1 Starter Crab as baseline unit 1.
Appraisal efficiency scales the cash potential index — it does not change shells dug. Reflects how quickly you convert piles into spendable cash during active sessions. Offline hours multiply hourly shells for rough logout planning covered in offline earnings guide.
Using Results for Decisions
Before buying capacity, enter current crabs plus planned purchases — if hourly shells barely rise, merges beat expansions. Before logging off overnight, compare eight-hour offline estimates with and without a planned merge. Pair numbers with item flow on the items page and progression milestones in the walkthrough.
Redeem active codes for cash independent of calculator output — codes fund upgrades that change real rates faster than spreadsheet tweaks alone.
Frequently Asked Questions
How accurate is the shell calculator?
It estimates relative hourly shells using tier doubling math from the tier list. Actual in-game rates may vary with upgrades and patches.
What shell rate does Tier 1 use?
Tier 1 Starter Crab is the baseline rate of 1 shell unit per hour per crab in the calculator model.
Does appraisal speed affect shell digging?
Appraisal speed affects cash conversion, not dig rate. The calculator measures shells dug, not cash earned.
Should I include offline hours?
Multiply hourly output by planned offline hours, remembering the game may cap total offline accumulation.
Can I mix different tier counts?
Yes. Enter counts per tier — the calculator sums each tier contribution using approximate doubling per level.
