Tip calculator

How this calculator works

This calculator computes tip, tax, total bill, and per-person share from a restaurant or service subtotal. Enter the bill subtotal, choose a preset or custom tip percentage, add tax as a rate or exact dollar amount, and specify how many people split the bill evenly.

The tip applies to the pre-tax subtotal by default. Tax is calculated from the subtotal using either a percentage or a fixed amount you enter from the receipt. Total equals subtotal plus tax plus tip. Per-person amount divides the full total by the number of people.

Splitting bills fairly is one of the most common everyday math problems. This tool handles the arithmetic so you can confirm amounts before paying—useful for group dining, delivery orders, catering deposits, and travel in jurisdictions with unfamiliar tax rates.

The calculator shows math for your inputs. It does not prescribe tipping etiquette, which varies by country, service type, and personal preference.

In the United States, full-service restaurant tipping norms shifted upward over recent decades. Presets in the calculator reflect common ranges; custom percentage accommodates any policy your group agrees on. International travelers should verify local expectations—tipping is insulting in some cultures and mandatory in others.

What affects the result

Every field changes the totals. Small differences in tip base or tax entry method add up on large group tabs.

• Subtotal is the pre-tax food and beverage amount before tip. Include discounts if you enter the post-discount subtotal shown on the receipt.
• Tip percentage applies to the subtotal in this model. Presets reflect common U.S. full-service dining norms; custom percentage accepts any value including 0% where no tip is customary.
• Tax can be entered as a rate on subtotal or as an exact amount from the receipt. Dollar entry is preferable when the receipt shows rounded tax, multiple tax lines, or alcohol taxed differently.
• Number of people divides the final total equally. The calculator assumes an even split, not itemized shares by diner.

Changing tip from 18% to 20% on a $100 subtotal adds $2 to tip. Tax is independent of tip in this model because tip is calculated on subtotal, not on subtotal plus tax.

Split count rounds to at least one person. Entering 0 or leaving people blank should still produce a per-person total equal to the full bill for solo dining. Large parties should confirm whether the restaurant adds auto-gratuity before collecting individual shares.

Real-world examples

Standard dinner for two. Subtotal $86, tax 8%, tip 20%, 2 people. Tip is $17.20 on subtotal; tax $6.88; total $110.08; $55.04 each. Verify against the receipt if service charge is already included.

Large group with custom tip. Subtotal $124.50, tax 7.5%, tip 18%, 3 people. Useful for confirming whether 18% or 20% better matches your policy before collecting payment apps transfers.

After-tax tipping preference. If you tip on the post-tax total instead of subtotal, add tax to the subtotal field first or bump the custom tip percentage slightly. Pre-tax tipping on $80 with 8% tax yields $16 tip at 20%; tipping 20% on $86.40 after-tax subtotal yields $17.28.

Delivery with receipt tax amount. Subtotal $42, tax amount $3.15 (exact from receipt), tip 15%, 1 person. Dollar tax entry avoids rounding mismatch when local rates do not apply cleanly to every item.

Business meal budget check. Before expensing, confirm total against company policy caps. This calculator handles split math only—not reimbursement rules or alcohol exclusion policies employers may impose.

Bar tab with tax-inclusive pricing. Some venues include tax in menu prices. Enter subtotal carefully—double-counting tax inflates the total. When tax is included, leave tax rate at zero unless adding separate sales tax.

Catering deposit plus final bill. Deposits reduce the subtotal due at the event. Model only the remaining balance plus tip and tax on that balance, not the full quoted event cost twice.

Common mistakes

Double-tipping when gratuity is included. Many restaurants add automatic gratuity for large parties. Read the receipt before adding voluntary tip on top.

Tipping on the wrong base. This tool tips pre-tax subtotal. If your norm is after-tax, adjust inputs or percentage accordingly.

Using an even split when orders were uneven. The calculator divides equally. Itemized splitting requires separate math per diner; use the group total here only if everyone agrees to split evenly.

Entering post-tax subtotal while also adding tax again. That double-counts tax. Enter pre-tax subtotal unless you deliberately combine amounts.

Ignoring delivery fees and service charges. Platform fees may not go to the driver. Some people tip delivery workers separately from restaurant tips—this calculator does not allocate fees.

Forgetting tax-exempt or reduced-rate items. Use receipt tax when available instead of a blanket rate if items are taxed differently.

Splitting tip but not tax fairly. Some groups tip on subtotal individually then split tax—this calculator applies one tip rate to the whole subtotal and divides the grand total. Agree on method before paying.

Assuming delivery fee goes to the driver. Platform fees and restaurant delivery charges may not reach the person you want to tip. Many people add a cash or app tip directly to the driver separately.

When to use this calculator

Use this calculator for restaurants, bars, shared delivery orders, and catering when you need tip and tax on a subtotal with equal splitting. It is faster than mental math on large tabs and reduces disputes when collecting from a group.

For personal finance beyond dining—credit card payoff, loan payments, or savings targets—use dedicated calculators such as the credit card payoff calculator, loan payment calculator, or savings goal calculator. Everyday tipping does not affect those long-term plans, but accurate bill splitting keeps social and budget friction low.

This tool does not replace local customs. Tipping norms differ internationally; some countries include service in the price and discourage additional tips.

Keep a screenshot or note of the calculated per-person amount when collecting via payment apps to avoid rounding disputes. Consistency matters more than perfect cents when splitting among friends.

Counter-service and fast-casual venues may provide tip prompts on tablets suggesting percentages on post-tax totals. Those prompts are not standardized—this calculator keeps tip on subtotal so you control the base explicitly.

Wine service and tasting menus sometimes add separate service fees. Read whether those fees replace tip or supplement it before entering subtotal and tip percentage here.

Happy hour discounts reduce subtotal before tip in this model when you enter the discounted amount shown on the bill. Verify the receipt subtotal matches what you type—promotional pricing errors are common on busy shifts.

For travel abroad, currency and service-included pricing may make percentage tipping irrelevant. This calculator assumes a U.S.-style subtotal-plus-tip workflow.
