Budgeting Calculators
Free budgeting calculators: tips and gratuity, percentages, discounts and sale prices, cost of living, and everyday money math — instant results, no sign-up.
Budget Calculator (50/30/20 Rule)
The 50/30/20 rule is the simplest way to budget: half your take-home pay for needs, 30% for wants, and 20% for savings and debt repayment. Enter your monthly income and minimum debt payments to see your split.
Cost of Living Calculator
Moving between cities changes what your salary is worth. Enter your current salary and each city's cost-of-living index to see exactly what you need to earn to keep the same lifestyle.
Tip Calculator
No more mental math at the end of dinner. Enter the bill, pick a tip percentage, and split between any number of people — this calculator shows the tip, the total, and each person's share.
Percent Calculator
Percentages show up everywhere — discounts, tips, raises, tax, interest. This calculator answers the three basic questions: X% of Y, what percent of Y is X, and how much is left.
Discount Calculator
Black Friday, clearance racks, coupon codes — this calculator tells you exactly what you save and what you actually pay, including tricky stacked discounts.
Trip Gas Cost Calculator
Planning a road trip or just wondering what your commute really costs? Enter distance, fuel economy, and gas price to see gallons, fuel cost, tolls, and cost per mile.
