Calculators That Work

Every Calculator You Need, One Place

We built 10 calculators that solve real problems. The mortgage calculator breaks down your monthly payment including property taxes, insurance, and PMI with a full amortization schedule showing how much goes to principal versus interest each month. The loan EMI calculator handles home loans, car loans, and personal loans using the same formulas banks use.

For health tracking, the BMI calculator tells you if you're underweight, normal, overweight, or obese based on WHO standards. The calorie calculator uses the Mifflin-St Jeor equation to figure out exactly how many calories you need, then breaks it down into protein, carbs, and fat based on whether you want to lose weight, gain muscle, or maintain.

Students get a GPA calculator that works with 10+ grading systems - US 4.0 scale, Indian 10-point CGPA, UK degree classifications, German grading, you name it. Track your semester GPA, calculate cumulative GPA, and use the target feature to see what grades you need to hit your goal.

Home Loans and Mortgage Planning

Buying a house? The mortgage calculator doesn't just give you a number. It shows you the complete picture: principal and interest, property tax estimates, homeowner's insurance, PMI if you're putting down less than 20%, and HOA fees if applicable. Compare 15-year versus 30-year mortgages to see how much interest you'll actually pay over the life of the loan.

The amortization schedule breaks down every single payment for the entire loan. You'll see exactly how much of your first payment goes to interest (usually most of it) and how that shifts over time until your final payment is almost all principal. This matters when you're thinking about refinancing or making extra payments.

Loan EMI for Cars and Personal Loans

The EMI calculator works for any type of loan. Enter your loan amount, interest rate, and tenure in years and months. Get your exact monthly payment plus total interest over the loan period. The visual breakdown shows what percentage goes to principal versus interest.

Home loans typically run 7-9% interest for 15-30 years. Car loans are 8-12% for 3-7 years. Personal loans hit 10-24% for 1-5 years. Higher rates mean more of your money goes to interest instead of paying down what you actually borrowed. The calculator makes this obvious so you can compare offers from different banks.

BMI and Body Weight Analysis

The BMI calculator follows WHO guidelines: underweight is under 18.5, normal is 18.5-24.9, overweight is 25-29.9, obese is 30+. Enter your height and weight in metric (cm, kg) or imperial (feet/inches, pounds). Get your exact BMI number plus what category you fall into.

BMI isn't perfect - it doesn't account for muscle mass - but it's a quick screening tool doctors use worldwide. Athletes and bodybuilders will score high because muscle weighs more than fat. For everyone else, it's a decent starting point for understanding if you're at a healthy weight.

Calorie Counting and Macros

The calorie calculator figures out your BMR (Basal Metabolic Rate) - how many calories you burn just existing - using the Mifflin-St Jeor equation. Then it multiplies by your activity level to get TDEE (Total Daily Energy Expenditure). That's how many calories you need to maintain your current weight.

Want to lose weight? Subtract 500 calories for about 1 pound per week. Want to gain muscle? Add 300-500 calories and lift heavy. The macro breakdown gives you grams of protein, carbs, and fat based on your goal. High protein (30-40%) for muscle building, balanced macros for general health, higher carbs if you're an endurance athlete.

GPA Calculation Across Grading Systems

The GPA calculator handles US 4.0 scale (A=4.0, B=3.0, C=2.0, D=1.0, F=0), Indian 10-point CGPA, UK degree classifications (First Class, Upper Second 2:1, Lower Second 2:2, Third), German 1-5 scale where 1.0 is best, plus systems from Canada, Australia, Singapore, France, Netherlands, and China.

Add unlimited semesters and courses. Each course gets a grade and credit hours. The calculator weighs everything properly - a 4-credit A counts more than a 1-credit A. Track your semester GPA, cumulative GPA across all terms, and use the target feature to calculate what grades you need in remaining courses to hit your goal GPA.

Age Calculator with Zodiac and Planetary Ages

Enter your birthdate and the age calculator gives you exact age in years, months, days, hours, minutes, and seconds with a live countdown that updates every second. Total days lived, total hours, total minutes - all calculated precisely accounting for leap years and varying month lengths.

Get your Western zodiac sign (Aries through Pisces based on your birth month) and Chinese zodiac animal (Rat, Ox, Tiger, etc. based on your birth year adjusted for Chinese New Year). See what day of the week you were born. Calculate your age on other planets - you're way older on Mercury but barely a year old on Saturn because of how long their orbits take.

Restaurant Tips and Bill Splitting

The tip calculator handles any tip percentage - 15%, 18%, 20%, or custom. Split the bill evenly or calculate individual amounts. See total cost including tip, per-person amounts, and exactly what to pay.

The bill splitter goes deeper. Track who ordered what, handle shared appetizers and drinks, distribute tax proportionally, and choose whether to split tip equally or by bill proportion. Everyone pays their fair share down to the cent. Select who paid and instantly see who owes them how much.

Discount Calculator for Smart Shopping

Add up to 10 products with their discount percentages and original prices. The discount calculator shows you the final price for each item, how much you save per item, total savings across everything, and your overall discount percentage. Perfect for comparing deals during Black Friday, holiday sales, or clearance events.

The calculator updates in real time as you type. Add items, remove items, change percentages - everything recalculates instantly. Share your savings on social media or download a shareable card showing how much you saved. Because bragging about a good deal is half the fun.

Why These Calculators Don't Suck

Every calculator calculates as you type. No submit buttons, no page reloads, no waiting. Type a number and boom - instant result. That's how it should work.

We don't collect data. At all. No email signup, no cookies, no analytics tracking your every move, no selling your info to advertisers. The calculator runs entirely in your browser. Your numbers never hit our servers because we don't have servers to hit.

No ads. No popups. No "subscribe to our newsletter" harassment. No "upgrade to premium for more features" upsells. Every calculator is 100% free with every feature unlocked. We built these because we needed them and got tired of sketchy calculator sites that are basically malware wrapped in a web page.

Metric and Imperial, Any Currency

Health calculators accept kilograms or pounds, centimeters or feet and inches. Financial calculators work with dollars, rupees, euros, pounds - we don't care because we're just doing math. Enter numbers in whatever format makes sense to you.

The mortgage calculator, loan EMI calculator, BMI calculator, calorie calculator, GPA calculator, age calculator, tip calculator, discount calculator, and bill splitter all adapt to how you want to use them. No forced unit conversions, no currency symbols that don't match your location.

How the Math Actually Works

We show our work. The mortgage calculator displays the full amortization table - every payment for 15 or 30 years showing principal, interest, and remaining balance. The loan EMI calculator breaks down the formula so you understand why your EMI is what it is. The GPA calculator explains how it converts between grading systems.

This isn't a black box that spits out numbers. You can see exactly what's happening and verify it yourself. Check it against your bank's numbers, your doctor's BMI chart, your school's GPA system. The math is standard, verified, and transparent.
