Grand Total

Tip is split proportionally — someone who spent more pays a larger share of the tip.

How the split is calculated

Each person pays their own subtotal plus a tip share proportional to what they ordered — not a flat equal fraction of the tip.

Formula
Grand Subtotal = sum of all amountsTotal Tip = Grand Subtotal × Tip% ÷ 100Person's Tip Share = (their amount ÷ Grand Subtotal) × Total TipPerson's Total = their amount + their Tip Share

Example — 3 People, 15% Tip

Charlie₹20016.7%₹30₹230
Total₹1,200₹180₹1,380

Why proportional matters

Splitting ₹180 equally gives each person ₹60 in tip — but Alice ordered only ₹400 while Bob ordered ₹600. Equal tip would undercharge Bob and overcharge Alice. Proportional split means Bob (50% of the bill) pays 50% of the tip: ₹90. Alice (33%) pays ₹60. Charlie (17%) pays ₹30. Everyone pays their fair share.

Frequently Asked Questions

The tip is proportional to each person's subtotal — whoever ordered more pays a higher share of the tip. Splitting the tip equally would overcharge people who ordered less and undercharge those who ordered more. Proportional allocation matches what each person actually contributed to the total bill.
