What does the planner calculate?

It models how many rolls or world-clears a summon or upgrade costs when you enter your own income per run.

Is the planner based on official values?

No — it uses only the numbers you enter and never guesses Anime Stars prices or drop rates.

Primary tool

Anime Stars Calculator – Upgrade ROI & Planners

Model how many story first-clears or farm runs a purchase costs, and check whether an upgrade pays for itself (runs-to-break-even). Both tools use only the numbers you enter and never guess Anime Stars prices, odds, or drop rates.

Quick answer

Enter your own per-run gems/gold in Part 1 to see how many runs a purchase costs, and Part 2 to see if an upgrade with a higher per-run income reaches break-even in fewer runs than saving for a bigger unit. It never guesses in-game prices.

Buy or grind first?

Run the ROI tool (Part 2) — a cheaper upgrade that raises per-run income can beat saving for a big unit.

A 5,000 gems purchase needs ~3 runs (~0.0h).

Is that upgrade worth it? (ROI)

If an upgrade raises your per-run income, it pays for itself once the extra income covers its cost. Enter your own numbers.

Break-even in ~15 runs.

After 15 runs the upgrade is pure profit. If that's fewer runs than saving for a bigger unit — upgrade first.

Both tools use only the numbers you enter — we never guess Anime Stars in-game prices, star-level odds, drop rates, or cost tables. Treat your per-run income as a starting sample, not a guarantee. ROI is one decision input; factor in fun and roster needs too.
