Stimulus check rebate calculator

There are a number of calculators out there for determining the rebate one can expect from the recently passed stimulus package, of course these all require you to give your income over to some website. Couple that with the pervasive tracking going on nowadays, you just told Facebook, Google and lord knows how many others your income from the last year, valuable information there. So I put together a spreadsheet that will give one an indication of how much the rebate will be, find it here:
Excel version
Numbers version
Just put your income into the appropriate cell in the first row and the rebate will show at the bottom.
