A clean, fast basic calculator for everyday arithmetic. Add, subtract, multiply and divide with a single click — right in your browser, no signup.
Tip: your keyboard works too — digits, + − * /, Enter (=), Backspace, Esc.
This is a straightforward pocket calculator for the math you do every day: adding up a grocery run, subtracting a discount, multiplying quantities, or splitting a total. It handles the four basic operations — addition, subtraction, multiplication and division — plus a percent key and chained calculations, so 60 × 1.20 ÷ 4 flows as naturally as it would on a physical calculator.
Unlike the wage and tax calculators on this site, there is nothing to configure here: no pay frequencies, no tax brackets, no filing statuses. Type the numbers, press the operator, press equals. Results appear instantly as you work, and the small expression line above the display always shows the full calculation so a mistyped digit is easy to spot before you commit.
Everything runs locally in your browser with JavaScript — your numbers never leave your device, nothing is stored, and the page works offline once loaded. The keypad buttons are large enough for touchscreens, the full keyboard works too (digits, + − * /, Enter for equals, Backspace to delete, Escape to clear), and the design follows your system's light or dark mode automatically.
Real-world math is rarely a single operation. A restaurant bill needs the tip added and then split; a sale price needs the discount subtracted and then tax added. This calculator chains operations the way a pocket calculator does: each time you press an operator, the pending operation is evaluated first, so 60 + 12 = ÷ 4 = runs as (60 + 12) ÷ 4 = 18 without retyping intermediate results.
The percent key is the shortcut for the most common chain of all. Pressing % converts the current entry to hundredths on the spot — 15 becomes 0.15 — so '15% of 200' is just 200 × 15 %, giving 30 directly. Combine it with chaining for discount math: 80 − 20 % = gives 64, the sale price, in three keypresses.
One honest caveat: like a pocket calculator, operations evaluate left to right as you press them, not by strict mathematical order of operations. 2 + 3 × 4 = gives 20, because (2 + 3) is evaluated when × is pressed. If you need strict PEMDAS behavior, compute the multiplication as its own step first, then add.
This page is deliberately simple — and that simplicity is its limit. The moment a calculation involves pay periods, tax brackets, percentages of changing values, or splitting among people with different shares, a dedicated tool gives a better answer with less room for error.
For money math, WageWiseO's specialized calculators take over: the Percentage Calculator handles discounts, tips and percent change with labeled modes; the Tip Calculator splits bills among any number of people; the Discount Calculator adds sales tax to the markdown; and the Hourly to Salary Calculator converts wages across pay periods. Each one asks for exactly the inputs its formula needs, so there is nothing to remember and nothing to mistype.
Think of it this way: reach for this simple calculator when the math fits in one line — 7 + 8, 240 ÷ 12, 15% of 200. Reach for a dedicated calculator when the problem has named parts, like gross pay, deductions, or tip percentages. Both are free, both run in your browser, and both are one click away in the navigation above.
Every calculation on this page is one of four basic operations, applied to the number on the display.
**7 + 8 = 15.** Press 7, then +, then 8, then =. The running expression shows above the display so you always see what you typed.
**A $60 bill split 4 ways with 20% tip:** first 60 × 1.20 = 72 (bill plus tip), then 72 ÷ 4 = 18 per person. Two chains, ten seconds.
**15% of 200:** press 200 × 15 % — the % key converts 15 to 0.15 immediately, giving 30. No need to divide by 100 yourself.
Yes — everything runs in your browser with JavaScript. No numbers are sent to any server, and there is no signup or account.
Yes. Type digits 0-9, the decimal point, +, -, * and / on your keyboard; Enter works as =, Backspace deletes the last digit, and Escape clears everything.
It chains like a physical pocket calculator: 2 + 3 × 4 = evaluates left to right as (2 + 3) × 4 = 20, pressing = after each operator. For strict math order of operations, do the multiplication first as its own step.
The display shows 'Error' and the calculator resets on your next keypress. This happens on division by zero or a result too large to display.
Yes — the layout uses large touch-friendly buttons and works in both light and dark mode, following your system setting.
For pay math, use the dedicated tools: the Percentage Calculator for discounts and tips, the Hourly to Salary Calculator for wage conversions, and the Tip Calculator for splitting bills.
