A script for calculating hourly wage?

[electrolyte]

Is there a script or a site or calculator or something (or how hard would it be to make this?) where you can type in how long a HIT took you and the amount it paid and the script gives you what the hourly wage for that is? It doesn't need to be visible on MTurk or a script on the site at all. Just some utility on the desktop or a website would work, too. Any ideas? Thanks!

probably be easier to keep a spreadsheet and just keep an accurate count of your time spent working
