Can I calculate last year's take home pay with my completed tax return?

My wife recently asked me what our take-home pay was last year. This sounded like an easy exercise now that I have my completed, TurboTax generated tax return. But I'm not sure which income and which taxes/payments to use to calculate this number. Might anyone be able to offer a simple formula using the specific values on a tax return?
