Calculators
Fast answers to everyday money and life math.
Age Calculator
Calculate your exact age — not an approximation — from your date of birth: full years, remaining months and days, total days lived, and a countdown to your next birthday.
Budget Split Calculator
Apply the classic 50/30/20 budget rule to your monthly take-home pay — or set any split you like. Enter your income and three percentages to instantly see dollar amounts for needs, wants, and savings, plus anything left unallocated.
Calorie Deficit Calculator
Enter your stats, activity level, and weekly loss goal to see your maintenance calories and a sensible daily target — based on the widely used Mifflin-St Jeor equation.
Car Loan Calculator
Work out what a car really costs per month: enter the vehicle price, down payment, APR, and loan term to see the amount financed, the monthly payment, and the total interest you would pay over the life of the loan.
Date Difference Calculator
Measure exactly how much time separates two dates: total days, weeks, a full calendar breakdown in months and days, and how many of those days are working days rather than weekend days.
Freelance Hourly Rate Calculator
Enter your target yearly income, business expenses, and realistic billable hours to see the minimum hourly rate that keeps you whole.
Percentage Calculator
Enter any two values and see every percentage answer at once — a percentage of a number, one number as a percent of another, and the percent change between them.
Rent Split Calculator
Enter the monthly rent, utilities, and both incomes to see what a fair split looks like — equal halves versus proportional to what each person earns.
Sales Tax Calculator
Calculate US sales tax in either direction: apply your combined state and local rate to a pre-tax price, or reverse the math on an out-the-door total to recover the original sticker price.
Savings Goal Calculator
Set a savings goal, your current balance, and a monthly deposit — see the exact number of months (and years) until you get there.
Tip Split Calculator
Enter the bill, tip percent, and how many people are splitting — get the tip, grand total, and exact amount per person in real time.
VAT Calculator
A fast, currency-neutral VAT calculator: enter an amount plus a rate, say whether your figure excludes or includes VAT, and get the net, VAT, and gross values instantly.
