Why Do We Still Need Tip Calculators?

Easy Ways to Figure Out Tips — and Why It Shouldn’t Be This Complicated

Let’s be honest: figuring out a tip shouldn’t feel like a math quiz. Yet every day, millions of Americans pull out their phones or ask Siri, “What’s 20% of $37.58?” just to leave a tip that feels socially acceptable.

From mental math hacks to built-in tip calculators on apps, we’ve created a whole industry of tools just to navigate an outdated system. Why? Because tipping in America has become confusing, inconsistent, and overly dependent on guilt.

But if you still need to calculate a tip, we’ll help you do it—and then we’ll explain why you shouldn’t have to.

Quick Ways to Calculate a Tip

Whether you’re dining out, getting a haircut, or picking up takeout, here are 3 quick methods:

1. Mental Math: The “Double Then Half” Trick

If you’re aiming for 15%:

Take 10% of the total (move the decimal point one place left). Halve that number. Add both together.

Example:

Bill = $40

→ 10% = $4

→ Half of that = $2

→ Total tip = $6 (15%)

2. The 20% Shortcut

This is the most common tip in the U.S. and easy to compute:

Move the decimal point one place left (10%) Double it.

Example:

Bill = $60

→ 10% = $6

→ 20% = $12

3. Use a Tip Calculator App or Built-In Tool

Most digital payment apps and phones have calculators:

Ask your voice assistant: “What’s a 20% tip on $85?” Use the built-in “Tips” section on restaurant POS systems. Or try our simple web-based calculator below

But Wait — Why Do We Even Need Tip Calculators?

Here’s the bigger issue: Tipping shouldn’t be this hard.

Customers are expected to:

Know when to tip Know how much to tip Know if the worker relies on tips or earns a living wage

On top of that, percentages vary depending on the industry, region, and quality of service—and some businesses even suggest tipping before service is provided.

This isn’t hospitality. This is homework.

What’s the Alternative?

💡 Just pay workers fairly. In many countries, tipping is rare or nonexistent because employees are compensated through wages—not customer math.

In Japan and most of Europe, service is included in the price. No mental math, no awkward prompts, no guesswork.

Final Thought

Yes, we can help you calculate tips. But the fact that you need a tool at all is part of the problem.

Tipping culture has gotten so out of hand that we’ve normalized the confusion.

At EndTippingCulture.org, we believe in simple, fair pricing—and paychecks that don’t depend on the whims of strangers. Let’s stop solving for tips and start solving the system.
