Formula / how it works
Everyday estimators combine simple arithmetic with conventional rules of thumb (splits, tips, DIY material allowances, fuel math). Treat outputs as planning aids, not contractor quotes, tax filings, or binding agreements. For the Tip + Tax Combo, the labeled fields (Subtotal (money), Tax % (%), Tip % (of subtotal) (%), Split between) drive the live result panel.

How to use
Steps

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.
- 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.
- Tip and split tools show exact arithmetic; decide how to round coins in your group’s favor.
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).
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.
