Restaurant Tip Calculator — Dining & Bars
The restaurant tip calculator is the most searched tip scenario. In the US, the standard is 15–20% of the pre-tax bill — but practice varies significantly. Use the calculator above, select the "Restaurant" preset, and enter your bill to get the exact tip amount and per-person breakdown for your group.
| Service Quality | Tip % | Example: $80 Bill |
|---|---|---|
| Poor / Incorrect order | 10% | $8 tip → $88 total |
| Adequate service | 15% | $12 tip → $92 total |
| Good service | 18% | $14.40 tip → $94.40 total |
| Excellent service | 20% | $16 tip → $96 total |
| Outstanding / Special occasion | 25%+ | $20 tip → $100 total |
Group dining tip: For parties of 6 or more, most US restaurants automatically add an 18% gratuity (check your bill!). If a gratuity is already included, no additional tip is required — though rounding up for exceptional service is always appreciated. Our calculator shows "Split Among" to handle any group size.

Split Bills in 4 — Divide Bills Equally
Split bills in 4 is one of the most common bill-splitting needs — splitting a dinner, a hotel stay, or a subscription with three friends. Use the "+ people" stepper above to set 4, and the calculator instantly shows each person's share including tip.
For split bills into 4 payments (Buy Now, Pay Later style), apps like Klarna and Afterpay can split the total across 4 bi-weekly payments. However, these apply to purchases — for restaurant and dining bills, use our in-person splitter above which divides immediately.
Delivery & Service Tip Calculator
A delivery tip calculator (DoorDash, Uber Eats, Grubhub, Amazon Fresh) uses the same formula as any tip — but the etiquette is different. Delivery drivers use their own vehicles, pay their own gas, and often only keep a portion of the platform fee. The tip is their primary take-home from your order.
| Service | Suggested Tip | Minimum |
|---|---|---|
| DoorDash / Uber Eats | 15–20% of order | $2–3 for small orders |
| Grocery Delivery (Instacart) | 15–20% | $5 (complex orders) |
| Taxi / Rideshare (Uber/Lyft) | 15–20% | $1–2 for short rides |
| Hotel Housekeeping | $3–5 per night | $2/night minimum |
| Valet Parking | $3–5 when picking up | $2 |
| Moving Help | $20–50 per mover | $10 for small moves |
Tax and tip calculator: In some states and countries, tax is already included in menu prices (UK VAT model). When this is the case, tip on the pre-tax amount for restaurants — but for delivery platforms, tip is typically calculated on the subtotal before platform fees and taxes. Our calculator lets you enter whichever amount is relevant.
Salon & Tattoo Tip Calculator
Beauty service tips differ from restaurant tips because sessions are longer, the service is more personal, and the professional often rents their station rather than earning a salary. Always tip on the service cost, not the product cost (e.g., tip on the haircut, not the bottle of shampoo they sold you).
| Service | Tip Range | Example: $150 Service |
|---|---|---|
| Hairdresser / Color Treatment | 15–20% | $22.50–$30 |
| Nail Salon (full set, gel) | 15–20% | $9–$12 on $60 |
| Tattoo Artist | 15–25% | $30–$50 on $200 |
| Spa / Massage Therapist | 15–20% | $15–$20 on $100 |
| Barber | 15% | $5–$8 on $35 |
| Eyelash Extensions | 15–20% | $22–$30 on $150 |
Tattoo tip calculator note: For large, multi-session tattoos, tip per session (not on the total quoted estimate). A 20% tip on each 4-hour session is the norm. If your tattoo artist sketched a custom design, that creative work justifies 20–25%. For a simple lettering or flash tattoo, 15–20% is standard.
How to Split Bills Based on Income
A strict 50/50 split works when two people earn similar incomes. But when there's a significant income gap — between roommates, couples, or friends — an income-based bill split is mathematically fairer. Toggle "Split by income proportion" above and enter each person's monthly income to see the proportional breakdown.
Roommate bills: For monthly shared bills (rent, utilities, subscriptions), calculate each person's income as a percentage of total household income, then apply that percentage to each shared expense. A household earning $10,000/month total where one earns $6,000 (60%) and the other $4,000 (40%) should split a $1,200 rent bill as $720 and $480 — not $600 and $600.
Tip Calculator Formula — How It Works
The tip calculator formula is simple: Tip = Bill × (Tip % ÷ 100). Here's how the full chain of calculations works, which is exactly what happens instantly in the calculator above:
- Tip Amount: Bill × (Tip% ÷ 100). Example: $75 × 0.20 = $15.00 tip
- Total Bill: Bill + Tip. Example: $75 + $15 = $90.00 total
- Per-Person Share: Total ÷ Number of People. Example: $90 ÷ 3 = $30 per person
- Round-Up Tip: Take the raw tip, apply Math.ceil() to the nearest dollar. $15.38 → $16. This slightly increases the tip amount, simplifying cash payment.
- Income-Weighted Share: Person's Income ÷ Total Group Income × Total Bill. Example: earns $4K of $10K total (40%) → pays 40% × $90 = $36
The 20 tip calculator shortcut: to calculate 20% mentally, divide the bill by 5. $85 ÷ 5 = $17 tip. For 15%: divide by 10 (= 10%), then add half. $85 ÷ 10 = $8.50, plus $4.25 = $12.75 tip.
Apps That Split Bills Into 4 Payments
Searching for apps that split bills into 4 payments? This typically refers to two different things: (1) Buy Now, Pay Later (BNPL) apps that split a purchase into 4 installments, and (2) apps that split a bill among 4 people.
| App | Type | Best For | Cost |
|---|---|---|---|
| Klarna | BNPL (4 payments) | Shopping, online purchases | Free if on-time |
| Afterpay | BNPL (4 payments) | Retail, fashion | Free if on-time |
| Splitwise | Group bill splitting | Ongoing shared expenses | Free / $3.99/mo Pro |
| Venmo | Payment + split | Friends, restaurants | Free (3% credit card fee) |
| Settle Up | Group expense tracker | Trips, roommates | Free |
For restaurant or dining bills, Venmo is the most common US solution — charge friends directly from the app after using our calculator to determine each person's exact share including tip. For ongoing shared household bills (rent, utilities), Splitwise tracks running balances and settles up periodically.
Frequently Asked Questions
How much should I tip at a restaurant?
The standard restaurant tip in the US is 15–20% of the pre-tax bill. Tip 15% for adequate service, 18% for good service, and 20% or more for excellent service. For a group of 6 or more, most restaurants automatically add an 18% gratuity. In India, 10–15% is standard and appreciated — not always expected.
What is the tip calculator formula?
Tip = Bill Amount × (Tip Percentage ÷ 100). For example, a 20% tip on a $50 bill: $50 × (20 ÷ 100) = $10 tip. Total = Bill + Tip = $50 + $10 = $60. Per person (split 4 ways): $60 ÷ 4 = $15 each.
How to split bills with friends?
Use the bill splitter above: enter the total bill, set tip %, then set the number of people. For equal splits, each person pays the same total amount including tip. For unequal splits (based on what each person ordered), enter individual amounts per person. For income-based splits, toggle "split by income" and enter each person's income percentage.
How much to tip a tattoo artist?
Tip tattoo artists 15–25% of the tattoo cost. For a $200 tattoo, a 20% tip = $40. Tattoo artists are skilled craftspeople who spend significant time on custom work — anything under 15% is considered low. For exceptional work, large custom pieces, or when the artist gave you a discount, 25% or more is appropriate.
How much to tip on DoorDash?
Tip DoorDash drivers at least 15–20% of the order total, or a minimum of $2–3 regardless of order size (especially for small orders). DoorDash drivers use their own vehicles and pay fuel costs. On a $20 order, tip at minimum $3–4. For long-distance deliveries or bad weather, tip 20–25%. The tip goes directly to the driver.
Should couples split bills 50/50?
The fairest approach depends on income. A strict 50/50 split disadvantages the lower earner — proportional income splitting is more equitable. For example, if one partner earns $6,000/month and the other $4,000/month, they split 60/40. Use our income-based split toggle above to calculate this automatically for any number of people.
How to calculate tip on iPhone?
Open Calculator on iPhone, enter bill amount, tap the percentage key, enter tip %, then tap equals. Or say "Hey Siri, what is 20% of $85?" for instant calculation. For exact per-person splits, our mobile-optimized Tip Calculator above works on any iPhone browser — no app download needed, just bookmark it.
How much to tip a hairdresser or nail salon?
Tip hairdressers and nail technicians 15–20% of the service total. For a $60 haircut, tip $9 (15%) to $12 (20%). Tip the same for nail manicures and pedicures. If your stylist is also the salon owner, tipping is still appreciated (though some owners say it's not required). For color treatments or complex styles, 20% is standard.
