Bookmarklet: Wage Calculator

While searching for employment, I realize I can’t be super picky - but my household does have needs! Because of this, I’ve developed a quick calculator / bookmarklet for the browser that I thought I’d share. It allows you to enter a yearly or hourly amount, and it shows the corresponding amounts. This tells you if that salary posting fits within your needs.

Features

Takes hourly or yearly wage. If amount is 200 or greater, assumes its a yearly amount.
Shows wages in yearly, monthly and hourly
Shows Gross, Company Net (assuming 25% tax bracket relatively), Independent Net (assuming 25% + 15.3% tax for medicare/social security, etc)
Configurable to take in other rates of tax

Here’s the bookmarklet - drag it to your book mark bar:

Calculate Wage

The UnMinified version:

function bookmarklet()
{
  var independentTax = 15.3;
  var taxBracket = 25;
  var amount = prompt('amount:');
  if (amount) {
    if (amount < 200) {
      amount *= 2080; // 40 hrs a week/ 52 weeks
    }
    var output = "Gross: $" + amount + "/yr - $" + Math.round(amount/12) 
               + "/mo - $" + Math.round(amount/2080) + "/hr\n";
    var taxminus = amount * (taxBracket/100);
    output += "Cmp Net: $" + Math.round(amount-taxminus) + "/yr - $" 
           + Math.round((amount-taxminus)/12) + "/mo - $" 
           + Math.round((amount-taxminus)/2080) + "/hr\n";
    taxminus = amount * ((taxBracket+independentTax)/100);
    output += "Ind Net: $" + Math.round(amount-taxminus) + "/yr - $" 
           + Math.round((amount-taxminus)/12) + "/mo - $" 
           + Math.round((amount-taxminus)/2080) + "/hr";
    alert(output);
  }
}
