Pop Quiz: Which statistics formula, when shown to a math-challenged student, causes the student to close the textbook so fast that it blows out the candles in the room?

If you answered, "all of them," you would probably be correct. However, the answer most relevant to the newest calculator (#222) is, the standard depreciation formula.

Thankfully, as you will see from the example tutorial on the page, solving for variance and standard depreciation is MUCH easier than deciphering the formula! -Dan

Hi! Hope you are having a great summer.

In case you've been wondering why it's been several months since I last announced a new calculator, it's because I've been buried in the learning curve of redesigning the site and its calculators to accommodate small-screen mobile devices. It's without a doubt the most complex work-related project I have ever tackled -- to the point I've nearly given up on more than one occasion.

None-the-less, I'm happy to report that I finally feel like I'm getting close to coming up with a new responsive design. But that's just the first hurdle. The next hurdle will be building the new design into 252 pages on the site. In the meantime I took a break today to create a new calculator for the site just so you will know I'm still among the living. :-)

Website Calculator Programmer
Web programmer specializing in creating javascript calculators for websites. I have been selling ready-made and custom calculators for websites since 1997 from my main website, Web Winder Website Calculators.

In August of 2010 I started a second website for the purpose of showcasing my work and for providing a place for the general public to simply use many of the calculators I've created -- free of charge. The site, Free Online Calculator Use, currently has more than 150 calculators (and growing), covering all financial topics as well as math, weight-loss, conversion, and time.
