Calculate an upgrade payback period

The problem

Upgrade prices are often set by intuition rather than incremental benefit.

Practical procedure

Divide the upgrade cost by the additional net resources earned per turn, then compare with the remaining expected session length.

Worked scenario

A 60-coin upgrade that adds 6 net coins per turn needs 10 turns to recover its cost.

Acceptance check

Verify the simulator shows the same break-even estimate and disclose that simple payback ignores opportunity cost.

Apply the method

Use the related interactive tool to try the concept on an inspectable example. Record the starting assumptions and expected result before changing settings, then compare what the tool actually does. Where the result differs, keep the release marked experimental and document the discrepancy.
