Become an Anime Billionaire Tools & Calculators

These tools help you make data-driven decisions in Become an Anime Billionaire. Whether you are planning your next rebirth, deciding which units to fuse, or tracking codes, these resources save you time and currency.

Rebirth timing calculator

Knowing when to rebirth is the most impactful decision in the game. Use these guidelines to time your rebirths perfectly:

When to rebirth checklist

• Your income growth has slowed to less than 10% per minute of active play.
• The next meaningful upgrade costs more than 5 minutes of accumulated income.
• You have filled all available base slots with your best units.
• You have enough cash to meet the rebirth cost threshold.
• You understand how rebirth points work (see the Controls page).

If all boxes are checked, perform a rebirth. If not, continue grinding and check the Tier List for upgrade priorities.

Unit comparison guide

When deciding between units, compare these factors:

Factor	What to Check
Income rate	Cash per minute — higher is better
Rarity tier	Higher rarity has better base stats
Fusion potential	Can this unit be fused? How many duplicates do you have?
Rebirth synergy	Does this unit benefit from your rebirth multipliers?
Availability	Is this unit from a limited-time event or code?

Use the Tier List as your primary reference and the Players hub for detailed mechanics.

Income optimization planner

Maximize your total base income with this systematic approach:

Step 1: Audit your current base

List every unit in your base and note their income rates. Identify your lowest-performing units.

Step 2: Check upgrade paths

For each low-performing unit, check if:

• You have duplicates for fusion at the merge machine
• A higher-rarity replacement is available through rolling
• A rebirth point investment would boost its income

Step 3: Prioritize replacements

Replace units in this order:

1. F-Tier units with anything better
2. D-Tier units with B-Tier or higher
3. C-Tier units with A-Tier or higher
4. Unfused units that have duplicates available

Step 4: Re-evaluate after changes

After each replacement or fusion, recalculate your total income. Small improvements compound over time.

Code tracker

Keep track of which codes you have redeemed:

• thisissecret — Kiriko unit
• tyfor10k — 5 Friendship Lucky Blocks
• bonusgift — 5 Friendship Lucky Blocks

Visit the Codes page for the latest active codes and redemption instructions.

Gem spending guide

Gems are the premium currency in Become an Anime Billionaire. Spend them wisely:

Best gem investments

Investment	Priority	Why
Merge machine fusion	High	Permanent income boost from upgraded units
Premium rolls during events	High	Better odds for rare units during boosted rates
Base expansion	Medium	More slots means more income
Regular premium rolls	Low	Save gems for events when possible

Worst gem investments

Investment	Why to Avoid
Common unit fusions	Low return on investment
Speed-ups	Patience is free
Cosmetic items	No gameplay benefit

Roll strategy planner

Before spending currency on rolls, follow this decision tree:

1. Is there an active event with boosted rates? — If yes, roll now. If no, save currency.
2. Do you need specific units for fusion? — If yes, target those units. If no, roll for general progress.
3. Is your base full? — If no, roll to fill slots. If yes, save for premium rolls.
4. Do you have Friendship Lucky Blocks? — Use them strategically, not randomly. Check the Tier List first.

Progress tracking

Track your progression milestones:

• Rebirth count — How many times you have rebirthed.
• Highest unit rarity — The rarest unit in your collection.
• Base fill percentage — How many slots are occupied.
