Everyday Money
Fast everyday math — tips, discounts, percentages, budgets, salary, and the bite of inflation.
Percentage Calculator
Work out what one number is as a percentage of another, or find a percentage of any value. Enter a percentage and a base number to get the result instantly, plus the reverse relationship.
Tip Calculator
Work out the tip and total on any bill, and split it evenly between people. Enter the bill amount, your chosen tip percentage, and the number of diners to see what each person owes.
Discount Calculator
Find the sale price and the amount you save on any discount. Enter the original price and the discount percentage to see the final price and your total saving instantly.
Double Discount Calculator
See the true price when two discounts are stacked — like "20% off, then an extra 10% at checkout". Stacked discounts multiply rather than add, and this calculator shows the real effective rate.
Budget Calculator (50/30/20)
Split your monthly take-home pay into needs, wants, and savings using the popular 50/30/20 rule. Enter your income to see how much to allocate to each bucket.
Inflation Calculator
See how inflation raises the future cost of goods and erodes the purchasing power of money over time. Enter an amount, an inflation rate, and a number of years to see both effects.
Markup Calculator
Work out a selling price from your cost and a markup percentage. Enter what an item costs you and the markup you want to add to see the price, the profit per unit, and the equivalent profit margin.
Profit Margin Calculator
Find your profit margin from revenue and cost. Enter the price you sell at and the cost to produce it to see your profit per unit, your margin as a percentage of revenue, and the equivalent markup.
Commission Calculator
Calculate a sales commission from a sale amount and a commission rate. Enter the value of the sale and the percentage rate to see the commission earned and how much of the sale is left over.
Hourly to Salary Calculator
Convert an hourly wage into a yearly salary. Enter your hourly rate, the hours you work each week, and the weeks you work per year to see your weekly, monthly, and annual gross pay.
Pay Raise Calculator
See what a pay raise is worth. Enter your current salary and the raise percentage to find the increase amount and your new salary, plus how it compares with inflation.
Subscription Cost Calculator
Add up the true lifetime cost of a subscription. Enter the monthly price, how many years you expect to keep it, and any yearly price rise to see the total you will spend.
