What is Tiered Splitting?
- Split the bill based on role or seniority instead of equally
- Seniors pay more and juniors pay less to reduce fairness friction
3 ステップで完了
- 1
Enter the total amount (one tap from the receipt).
- 2
Tap 'Add member' and input participants (one group per line, comma-separated members within the same group).
- 3
Enter the tier weight per group (100 = even, 200 = double, 50 = half). Everyone's share appears, with one-tap rounding to 100 yen units.

よくある質問
傾斜計算アプリの実務的な疑問にお答えします
Q. What's a typical tier strength?
A. Directors typically pay 1.5–2x and new hires 0.5–0.7x of the average. Adjust based on group size and formality. See How to Calculate Tiered Splits for concrete examples.
Q. How should I handle the rounding leftover?
A. Round to 100 yen units and have the organizer absorb the difference — easiest in practice. The app handles this automatically via the calculation unit setting.
Q. Should welcome/farewell parties use a different ratio?
A. Typically the guest of honor pays nothing or half, while everyone else uses the standard tier. See How to Set Welcome/Farewell Party Fees for detailed examples.
