How the Anime Ball Battles reward calculator works
For each currency, the calculator adds the rewards on entries that are not marked as already included in your balance. It adds that subtotal to your current balance, then subtracts the result from your target. A target you have already reached leaves a deficit of zero.
Expected balance = current balance + unredeemed rewards
Still needed = max(target − expected balance, 0)
Coins and Gems are calculated independently. There is no exchange rate, summons cost, rarity probability or game economy database behind this tool. It does not predict drops, grant rewards or connect to your Roblox account.

The hypothetical-example button loads the values below. EXAMPLE-A and EXAMPLE-B are reminders invented for this demonstration, not game codes. Select Calculate to reproduce the result.
| Entry or result | Coins | Gems |
|---|---|---|
| Current balance | 100 | 20 |
| Target balance | 1,000 | 100 |
| EXAMPLE-A: not yet counted | 500 | 30 |
| EXAMPLE-B: already in balance | 200 | 10 |
| Additional rewards | 500 | 30 |
| Expected balance | 600 | 50 |
| Still needed | 400 | 50 |
The second reward is a historical checklist entry. It is already included in the starting balance, so the calculator does not add its 200 Coins or 10 Gems again. Your balance can be lower than an earlier reward if you spent some currency; the checklist does not reconstruct that spending.
Update the plan after you redeem
Replace Current Coins and Current Gems with the balances you can actually see in the game. Then mark the corresponding reward as already included. Calculate again to find the remaining gap. If you mark a reward without updating the current balance, the calculator will correctly exclude it from additional rewards, but your starting figure will be out of date.
A zero gap means your entered expected balance reaches the entered target. It does not confirm that a purchase is available or that any pending code will succeed. If you are comparing only balances, remove the reward rows and calculate without them.
What to check before trusting the result
- Already redeemed: update your current balance first, then mark the corresponding entry. Otherwise you might count the reward twice.
- Expired or uncertain code: remove it from your plan until you can confirm the reward. The calculator cannot validate a code.
- Same code twice: exact duplicate labels are rejected after surrounding spaces are removed. Different capitalization is preserved because codes may be case-sensitive.
- Whole units only: blank, negative, fractional and oversized numbers are rejected. Zero is valid. Each amount and calculated total is limited to one trillion units.
- Other spending: purchases, boosts, caps and rewards outside your entered plan are not modeled.
Your entries stay in your browser
Calculations do not send your labels, balances or results to us. If you explicitly save a plan, this browser stores it locally; shared-device users should clear it afterward. Optional analytics only measure fixed actions, never your entries. Read the privacy policy or .
