That's a pretty decent calculator. Good points: - It correctly showed Amazon's (crappy) vesting schedule (5/15/40/40%); - I like the attention to detail with showing round dollar numbers on the Y axis Areas for improvement: - I believe Amazon's offer factors in stock growth in their quoted dollar value for your initial grant. It looks like the calculator is working on the nominal value (which is what Amazon should do too as their method inflates their grant value); - I see no mention of 401k matches or vesting. - No mention of cliffs or the lack thereof - I'd probably show PTO days and company holidays too - It might be worth showing vesting schedules as it can matter if it's monthly vs annually; UI/UX suggestions: - This site has enough information where you could pick a level on many company's job ladders and it will correctly fill out bonus targets, grant ranges and so forth. Likewise it could show salary bands. For the big tech companies it'll probably be pretty accurate; - Arguably you can drop the table entirely - I'd make the company names more prominent above the total 4 year compensation figures. The font is too small. This should be highlighted - UI-wise I'd probably put the chart at the top and the offers side by side. It's weighted very much to the left column such that I get line wrap even on a 32" monitor (with the capped width). Even without the line wrap there's way more on the left column than the right. - The top heading is (IMHO) too big. Reduce this. - I'd move the Reset Form button, certainly from the top. Maybe next to the share link? - I think you need a clearer breakdown of each bar between salary and stock. I'd even add a third category of bonus. Put them in this order from top to bottom: stock, bonus, salary. So my suggested layout is: +---------+---------+ | Chart | Table | +---------+---------+ | Offer 1 | Offer 2 | +---------+---------+ If you ditch the table put the summaries to each side of the chart. I think the share link below the chart makes the most sense. The last thing I have to say is for anyone comparing offers, I would advise you to consider the growth in the company value to be 0. It may well be more. It certainly has been for the last decade but this has also been the longest bull market in modern history. It can also go down. Zero-growth assumed IMHO is a safer course of action. Put it this way: if you're putting in, say, that a company will grow 20% y/y why wouldn't you put all your money into it?
