How to Use the Tip & Split Bill Calculator

The Tip & Split Calculator is the ultimate dining companion designed to eliminate the awkwardness of dividing restaurant bills, bar tabs, and shared group expenses. Whether you are splitting a quick lunch equally among three friends or managing a complex dinner bill where everyone ordered completely different items, this tool handles the math instantly so you can focus on enjoying your night out.

Advanced Group Splitting: The "Amount Lock" Feature

While basic calculators only let you divide a grand total equally, this utility offers a powerful Custom Split mode tailored for real-world scenarios. If one person only ordered a small drink while the rest of the group shared a massive feast, you can use the innovative "Amount Lock" feature. Simply lock in a fixed, smaller payment amount for that specific friend, and use the "Auto Fill Remaining" button to instantly and evenly distribute the leftover balance among the rest of the group without doing any manual subtraction.

Step-by-Step Guide to Settling the Bill

1. Enter the Base Bill: Type in the total amount printed on your restaurant receipt.
2. Add Tip or Service Charge: Apply a standard percentage-based gratuity (such as 15% or 20%) or type in a custom flat tip amount.
3. Select Your Split Method: Choose a simple Equal Split, or switch to Custom Split to add individual names for a precise breakdown.
4. Adjust Individual Shares: Utilize the Amount Lock feature to adjust payments for specific people, then auto-fill the remaining balance.
5. Export & Request Money: Click the share button to instantly send a cleanly formatted breakdown directly to your group WhatsApp chat.

Frequently Asked Questions (FAQ)

Q: Can I use this tool offline inside a restaurant with bad network reception?
A: Absolutely! Because Hapsas operates as an offline-first Progressive Web App (PWA), the calculator works flawlessly in basements, crowded bars, and restaurants with zero internet or Wi-Fi connectivity.

Q: Can I share the final calculations with my friends?
A: Yes, once the exact math is calculated, you can use the built-in WhatsApp share button to send the final breakdown to your contacts so everyone knows exactly what they owe.

Q: Is my group's data and financial information kept private?
A: Yes. All split calculations and friend names you enter are processed 100% locally on your device via client-side JavaScript. None of your dining data is ever tracked, stored, or uploaded to any server.
