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

Person	Subtotal	Share	Tip	Total
Alice	₹400	33.3%	₹60	₹460
Bob	₹600	50.0%	₹90	₹690
Charlie	₹200	16.7%	₹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.
