Pregnancy Calculator

Estimate your due date, current week and key pregnancy milestones from your last period, an ultrasound, a conception date, an IVF transfer, or an existing due date.

This tool gives a general estimate only. Always confirm dates with your doctor, midwife or fertility clinic.

Salary Calculator

Convert any pay rate into hourly, daily, weekly, monthly and yearly figures, and estimate your net take-home pay.

Compound Interest Calculator

See how an investment grows over time with compounding returns and regular monthly contributions.

Body Fat Calculator

Estimate your body fat percentage using the U.S. Navy circumference method, plus fat mass, lean body mass and BMI.

This body fat percentage calculator uses simple tape-measure circumferences to estimate body composition for men and women. Enter your height, neck and waist (plus hip for women) to see your estimated body fat percentage, fat mass and lean body mass. It's a quick, equipment-free way to track progress over time — not a substitute for clinical body composition testing such as DEXA or hydrostatic weighing.

Time Card Calculator

Log clock-in and clock-out times for a full week and instantly get daily hours, weekly totals, overtime and estimated gross pay.

This time card calculator turns a weekly timesheet into worked hours in seconds. Enter clock in/out times and any unpaid break for each day of the week — overnight shifts are supported automatically, so a night shift that runs past midnight still totals correctly. The calculator adds up your regular and overtime hours using the threshold and multiplier you choose, and, if you add an hourly rate, gives you an estimated gross pay for the week that you can copy or print.

Time Calculator

Add or subtract time, find the difference between two clock times, or convert between days, hours, minutes and seconds.

This time calculator handles proper base-60 time math so 1 hour 30 minutes is treated correctly – never as the decimal 1.30. Use it to add or subtract durations, work out the time difference between a start and end time (including shifts that cross midnight), or convert a duration between days, hours, minutes and seconds. It's a handy tool for scheduling, cooking, workouts, or any project where you need to combine or compare durations quickly and accurately.

Amortization Calculator

Calculate your monthly loan payment and generate a full principal-and-interest amortization schedule, with optional extra payments.

This amortization calculator works out the fixed monthly payment on any standard fixed-rate loan and breaks every payment into principal and interest down to the final month. Add an optional extra monthly payment to see how much interest you could save and how much sooner the loan could be paid off. Figures are estimates for planning purposes, not a lender's official quote.

Car Loan Calculator

Estimate your monthly car payment including down payment, trade-in, sales tax and fees.

This car loan calculator estimates your monthly payment by factoring in the vehicle price, down payment, trade-in equity (including anything still owed on it), sales tax, dealer fees and your loan's APR and term. Choose a common term or set a custom one, and add an optional extra monthly payment to see how much interest you could save. Tax rules and fee structures vary widely by location, so treat the totals here as a planning estimate rather than a final financing offer.

Auto Loan Calculator

A fast, all-in-one view of your auto loan – payment, amount financed, total interest and total cost.

This auto loan calculator gives you a compact, all-in-one breakdown of a vehicle loan – monthly payment, amount financed after tax, fees and trade-in, and total interest over the life of the loan. Pick a common loan term or enter a custom one, then add an optional extra payment to instantly see how much sooner you could pay off the loan and how much interest that could save you along the way.

Dental Implants Cost Calculator

Get a ballpark estimate for dental implant treatment based on the type of procedure, number of teeth and any additional treatment needed.

This dental implants cost calculator estimates a price range for common implant treatments – from a single tooth implant to a full-mouth All-on-4 or All-on-6 restoration – including optional extras like extractions, bone grafts, sinus lifts, scans and sedation. Choose your currency and an approximate insurance coverage percentage to see an estimated out-of-pocket cost. Use it to get a rough sense of budget before your consultation; only a licensed dentist can give you an exact quote.

Percentage Calculator

Calculate percentages, percentage increase or decrease, and what percent one number is of another — instantly, in your browser.

This free percentage calculator handles the most common percentage questions in one place: finding what a percentage of a number is, working out what percent one value is of another, measuring a percentage increase or decrease between two numbers, and raising or lowering a number by a percentage. For example, 15% of 200 is 30, and increasing 500 by 20% gives 600. Students, shoppers comparing discounts, and anyone who needs a quick, accurate percent calculator online can use it for free.

Age Calculator

Find your exact age in years, months and days from your date of birth, plus total months, weeks, days and your next birthday countdown.

This age calculator works out your exact age from a date of birth using proper calendar-based math, not a simple year subtraction — so leap years and February 29 birthdays are handled correctly. Enter your date of birth and, optionally, a different "as of" date, to see your age in years, months and days, your total days lived, and how long until your next birthday. It's useful for forms, eligibility checks, birthday planning, or simply answering "how old am I?" exactly.

Discount Calculator

Calculate a sale price, find the discount percentage between two prices, or stack multiple successive discounts — with an optional tax step.

This free discount calculator works out the sale price after a percent-off discount, or reverses the math to find what discount percentage was applied between an original and sale price. It also handles stacked discounts correctly — two successive discounts, like 20% then 10%, are applied one after another rather than simply added together, so $1,000 becomes $800 and then $720, not $700. Shoppers comparing retail discounts, online sale prices or percentage-off offers can use it for free, with an optional tax step for the final total.

Tip Calculator & Bill Splitter

Calculate a tip, split the bill between any number of people, and see exactly what each person owes — with optional tax.

This free tip calculator and bill splitter works out the tip amount, the total bill, and each person's share in one step. Pick a quick tip percentage or enter a custom one, add the number of people, and it splits everything evenly — including an optional tax step, since tipping and tax customs vary by country. It's a fast way to calculate a tip and split a bill accurately at a restaurant, for a group order, or for shared expenses.

Fraction Calculator

Add, subtract, multiply or divide fractions and mixed numbers, with every answer simplified and shown as a decimal and percentage too.

This free fraction calculator lets you add fractions, subtract fractions, multiply fractions or divide fractions in one click, with proper fractions, improper fractions, mixed numbers, whole numbers and negative fractions all supported. Need to calculate fractions quickly? Enter your values, and this fraction calculator with steps shows exactly how the common denominator is found before the final answer. Every result is reduced automatically — a good fraction simplifier should always simplify fractions to lowest terms, so 12/18 is shown as 2/3, not left unsimplified. Alongside the simplified fraction you also get the mixed number, a fraction to decimal conversion and a percentage, and secondary modes let you simplify a single fraction, convert decimal to fraction, or compare two fractions. It's a reliable fraction calculator online and a handy mixed number calculator for students checking homework.

Simple Interest Calculator

Calculate simple interest and the total amount from principal, rate and time — or solve for principal, rate or time instead.

This free simple interest calculator online uses the standard simple interest formula, SI = P × R × T, to calculate simple interest on any loan, deposit or investment. Enter your principal, annual interest rate and time period in years, months or days, and this simple interest calculator with steps shows the total amount with simple interest instantly. Unlike a compound interest calculator, interest here is only ever earned on the original principal, never on interest already added — that's the simple interest vs compound interest difference. It also doubles as a principal interest calculator and simple interest rate calculator, since you can solve for principal, rate or time as well. Use it to calculate interest on a loan, a fixed deposit, or any simple interest calculation for school or everyday finance.
