Because Idle Planet Miner receives frequent updates (adding new planets, ships, and managers), "verified" spreadsheets can become outdated quickly. However, there are a few community staples that are widely considered accurate and are regularly maintained by the player base on Discord and Reddit.
Here is a guide to the best-available verified spreadsheets and how to use them to optimize your game.
Let’s assume you have downloaded the "IPM 1.5 Verified Master Sheet" (available via the official Discord #resources channel). Here is your 3-day action plan.

Verified spreadsheets include a "Time Loop" calculator. This tells you how long to leave your galaxy running before selling it for Credits. Most players sell too early or too late.
In the Idle Planet Miner community, a "verified" sheet isn't just a fancy title. It means the math has been checked against the current game version (v2.0+).
Because the devs update the game regularly—changing planet costs, market fluctuations, and room bonuses—a spreadsheet from six months ago could cost you weeks of wasted idle time. A verified sheet is maintained, peer-reviewed, and guaranteed to calculate correctly.

We’ve all been there. So, we do what any smart gamer does: we search for a spreadsheet.
But here is the catch. The internet is full of outdated, broken, or downright wrong spreadsheets. That is why the community has moved toward a new gold standard: Verified Spreadsheets.
Use the spreadsheet's Alloy Conversion Tab to see if it is profitable to buy base ore from the Market (using Credits) just to smelt it into alloys for crafting.
