When the Tip Calculator seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
The per-person amount does not multiply back to the total.
Rounding to cents can leave a one or two cent gap - add the remainder to one person share.
The total looks higher than my bill.
Check whether tax and service charges are already in the amount you entered.
I need custom shares, not an even split.
Even splits assume equal orders - settle uneven items by hand and use the tool for the shared remainder.
The tip percentage options do not match my country.
Enter any custom percentage - tips vary widely by region and service style.
Currency symbol is missing.
The tool is currency-agnostic - add your own symbol when reading the numbers.
Does it store my bill?
No - everything runs in your browser with nothing saved.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Forgetting tax when tipping on the subtotal
- Rounding per-person shares badly
- Splitting uneven orders evenly
- Assuming one tip rate fits every country
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
How is the tip calculated?
Bill amount multiplied by your tip percentage, then added to the bill for the grand total.
What tip percentage should I use?
Common restaurant ranges sit near 15 to 22 percent depending on country and service - adjust to local custom.
Can I split uneven shares?
The tool does even splits; subtract individual items by hand first, then split the shared remainder.
Is my bill stored?
No - calculations stay in your browser.
