WhatsApp bill split calculator — share the settlement in one tap
After every group dinner or outing in India, the same question: who owes whom? FairShare calculates the fairest split and opens WhatsApp with a ready-made message — names, amounts, and a link so friends can split their own bills free.
Built for how groups actually settle in India
UPI, cash, or one friend who paid the whole bill — log each expense in rupees, pick who shared it, and get the minimum number of payments to square everyone up. No Splitwise account, no ₹-per-month subscription.
One tap to WhatsApp
Share on WhatsApp pre-fills a clean summary: who gets money, who pays whom, and optionally every line item. Perfect for family groups, college trips, and office team lunches.
Private — nothing uploaded
Your group’s expenses stay on your phone or laptop. We never see names, amounts, or trip details. Works in Chrome and Safari on mobile.
Frequently asked questions
Does FairShare post to WhatsApp automatically?

Can I split only among some people for one expense?
Yes — toggle who shares each expense so drinks-only or cab-only splits are fair.
Is it really free?
Yes — no sign-up, no ads blocking the tool, no payment.
