Salary Calculator

Convert hourly wage to yearly income.

What does the Salary Calculator do?

The Salary Calculator is a financial tool designed to convert your hourly wage into various timeframes. It instantly breaks down your pay into Weekly, Monthly, and Yearly salaries. This helps you understand your gross income before taxes.

Who should use it?

This tool is specifically designed for US workers, freelancers, contractors, and part-time employees who are paid by the hour. If you are negotiating a new job offer or planning a budget, knowing your equivalent annual salary is crucial.

How the calculation works

The formula assumes a standard working year consists of 52 weeks. The math works as follows:

  • Weekly: Hourly Wage ร— Hours per Day ร— Days per Week
  • Yearly: Weekly Income ร— 52
  • Monthly: Yearly Income รท 12

Example Calculation

If you make $25 per hour working a standard 40-hour week:

  • Weekly: $1,000
  • Monthly: ~$4,333
  • Yearly: $52,000

Frequently Asked Questions

Does this include taxes?
No, this calculator shows "Gross Income" (before taxes). Your "Net Income" (take-home pay) will be lower depending on state and federal taxes.

What about unpaid time off?
The calculation assumes you work 52 weeks a year. If you take 2 weeks of unpaid vacation, subtract 2 weeks of pay from the yearly total.

BMI Calculator

Check your Body Mass Index score.

What is the BMI Calculator?

The BMI (Body Mass Index) Calculator helps you determine if you are in a healthy weight range for your height. It is a screening tool used by health professionals to categorize weight types.

Who should use it?

Anyone interested in monitoring their physical health. It is suitable for adult men and women. Note that BMI is not a diagnostic tool; it does not measure body fat directly but is a strong indicator of potential health risks associated with obesity or being underweight.

How calculation works

The metric formula is weight (kg) / [height (m)]ยฒ. Our calculator automatically converts pounds and feet if you prefer US Imperial units.

  • Underweight: BMI less than 18.5
  • Normal weight: BMI 18.5 to 24.9
  • Overweight: BMI 25 to 29.9
  • Obesity: BMI 30 or greater

Example

A person who is 5 feet 9 inches tall and weighs 160 lbs has a BMI of roughly 23.6, which falls into the "Normal" category.

FAQs

Is BMI accurate for athletes?
Muscle is denser than fat. Athletes with high muscle mass might have a high BMI but very low body fat. In these cases, BMI may not be accurate.

Currency Converter

Convert 40+ world currencies.

What is this Currency Tool?

This tool allows you to check the value of one currency against another. It covers major global currencies like the US Dollar (USD), Euro (EUR), British Pound (GBP), and Indian Rupee (INR).

Who is it for?

This is essential for travelers, online shoppers buying from international stores, and business professionals dealing with overseas clients. It helps you estimate costs quickly without doing complex math.

How it works

We use a baseline exchange rate table. When you enter an amount (e.g., 100 USD) and select a target currency (e.g., EUR), the calculator multiplies the amount by the current exchange factor.

Example

If the exchange rate for 1 USD is 0.92 EUR:
Converting $100 will give you โ‚ฌ92.00.

FAQs

Are these rates real-time?
These are estimated market rates used for general reference. Banks and exchange kiosks often charge a markup or "spread," so the actual rate you get at a counter might differ slightly.

Unit Converter

Convert Lengths (Meter, Inch, Mile, Foot).

What is the Unit Converter?

The Unit Converter solves the problem of switching between Metric (Meters, Centimeters) and Imperial (Feet, Inches, Miles) systems. It provides instant, precise conversions for length and distance.

Who needs this?

Students helping with homework, contractors needing to convert blueprints from meters to feet, or anyone dealing with height measurements.

How calculation works

Each unit has a fixed "factor" relative to a base unit (meters). The calculator uses these ratios to provide the answer.

  • 1 Inch = 2.54 Centimeters
  • 1 Foot = 0.3048 Meters
  • 1 Mile = 1.609 Kilometers

Example

If you are 5 feet 10 inches tall, that is 70 inches total. Converting 70 inches to centimeters results in 177.8 cm.

Age Calculator

Calculate exact age in years and days.

What is the Age Calculator?

This tool calculates your chronological age based on your Date of Birth. Unlike simply subtracting years, this tool accounts for the specific month and day to give you a precise answer.

Who is it for?

Useful for filling out official forms, determining eligibility for age-restricted services, or just satisfying curiosity about exactly how many days you have been alive.

How it works

The system takes the current browser date and subtracts your selected birth date. It calculates the difference in milliseconds and converts that into Years and Days.

Example

If today is 2024, and you were born in 1990, the calculator checks if your birthday has passed yet this year. If not, it correctly identifies you as 33; if yes, 34.

FAQs

Does it handle leap years?
Yes, the JavaScript Date object automatically accounts for leap years when calculating the total number of days.

EMI Calculator

Calculate standard EMI for loans with reducing balance interest.

What is this EMI Calculator?

This Equated Monthly Installment (EMI) calculator helps borrowers determine their monthly repayment amount for a loan using the standard reducing balance method. This is the formula most banks and financial institutions use.

Who should use it?

Anyone planning to take a home loan, car loan, personal loan, or education loan. This tool helps you understand your monthly financial commitment and total interest payable over the loan tenure.

How calculation works (Standard Formula)

The formula used is:

EMI = P ร— r ร— (1+r)โฟ / ((1+r)โฟ - 1)

Where:

  • P = Principal loan amount
  • r = Monthly interest rate (Annual Rate / 12 / 100)
  • n = Loan tenure in months

This method calculates interest on the outstanding principal balance, which decreases with each payment, making it more accurate and fair than flat-rate interest.

Example

If you borrow $2,500 at an annual rate of 10% for 3 months:

  • Monthly Interest Rate: 10% / 12 = 0.833%
  • Monthly EMI: $845.94
  • Total Interest: $37.83
  • Total Amount Payable: $2,537.83

FAQs

Why is this different from my earlier calculation?
The previous version used simple interest (flat rate). This standard formula uses reducing balance, which banks actually use, resulting in lower total interest.

What happens if I prepay the loan?
Prepaying reduces the principal, which lowers the total interest. This calculator assumes no prepayments.
