Frequently Asked Questions

How do I split a restaurant bill evenly?

To split a bill evenly, add the total bill plus tip, then divide by the number of people. CheckBuddy automates this: enter your bill, select tip percentage, choose how many people, and get each person's exact share instantly.

How do you calculate a 20% tip quickly?

The fastest way to calculate 20% tip: find 10% by moving the decimal left one place, then double it. For a $65 bill: 10% = $6.50, doubled = $13 tip. Or just use CheckBuddy for instant, accurate results.

Should I tip on the total or pre-tax amount?

Traditionally, tips are calculated on the pre-tax subtotal. However, many people tip on the total for simplicity since the difference is usually small. Either approach is acceptable - use what feels right to you.

What's the standard tip percentage in 2025?

In the United States, 18-20% has become the standard tip for good restaurant service. 15% is now considered the minimum for acceptable service. For exceptional service, 22-25% is appropriate.

How much should I tip for takeout or delivery?

For takeout, 10-15% is appreciated but optional. For delivery, 15-20% is standard, with a minimum of $3-5 for small orders. Tip more during bad weather or for complex orders.

Can I use CheckBuddy without internet?

Yes! CheckBuddy is a Progressive Web App (PWA). Install it to your phone's home screen and it works completely offline. Perfect for restaurants with poor signal or international travel.

Is CheckBuddy really free?

Yes, 100% free forever. No ads, no premium subscriptions, no in-app purchases, no hidden costs. We built CheckBuddy because we needed a simple, reliable bill splitter ourselves.

How do I split a bill when people ordered different amounts?

For unequal splits, each person can calculate their own items separately. CheckBuddy's even split works best when everyone ordered similar amounts. For complex itemized splits, calculate each person's subtotal individually.
