How to use this calculator

Compare daily currency sources and sinks to see net economy flow.

How the calculation works

Enter the design assumptions for the system you are balancing.
Tool2Do calculates a deterministic table or result from the displayed method.
Use export options only where the output is reusable game data.

Formula

Daily value = amount x frequency. Net flow = total sources - total sinks.

Example

Quests add 700 daily coins while upgrades remove 600, leaving +100 net daily flow.

Understanding your result

Use the output as a practical starting point, then review it before using it in an important workflow.

Game engine export

This gaming tool can export the visible result as structured JSON or CSV, plus text-based Unity, Unreal, and Godot snippets. The export is generated in your browser from the current result and is meant as a clean starting point for prototypes, balancing sheets, and engine-side data tables.

Assumptions and limitations

Calculations run locally in your browser.
These are balancing helpers, not universal game design rules.
Do not paste private production telemetry or player data.
