How to interpret results
- Grand total stacks tax and tip per the form’s order of operations.
- Per-person is an even split unless you adjust manually.
- Social norms vary — math is exact.
- On the Tip + Tax Combo, read the large primary result first, then secondary totals, then any chart or table.
- Each result is driven only by the labeled inputs (Subtotal (money), Tax % (%), Tip % (of subtotal) (%), Split between); anything not on the form (fees, holidays, clinical adjustments) is outside this estimate.
Common mistakes & gotchas
- Tipping on post-tax when your group agreed pre-tax (or reverse).
- Forgetting posted menu prices may exclude tax.
- Splitting uneven orders without adjusting shares.
- Forgetting to agree how to round coins or tip when splitting among friends.
- Ignoring waste factors on DIY quantities when the form labels them separately.
Worked example
Worked example — $50 bill, 7% tax, 18% tip (pre-tax tip)
- Tax = 50 × 0.07 = 3.50.
- Tip on pre-tax = 50 × 0.18 = 9.00.
- Total = 50 + 3.50 + 9.00 = 62.50.
- Open the Tip + Tax Combo (tip tax combo) and note the starting defaults (subtotal 80, tax % 8 %, tip % (of subtotal) 18 %, split between 2). These are demo numbers — not recommendations.
Result: With defaults (subtotal 80, tax % 8 %, tip % (of subtotal) 18 %, split between 2), the Tip + Tax Combo shows: Grand total $100.80; Per person $50.40. Re-run with your own numbers for a personalized estimate — illustrative only, not professional advice.
