Most offers these days are usually some variations of a 4 year plan that includes base, bonus, stock.
In a spreadsheet, put year 1-4, and all the items that break up.
Put all the items that make the comp. Don't forget things like 401k match and vacations. Companies like msft, that has a very significant monetary value.
Now two cases - current Co v/s new offer, or comparing 2 new offers.
In general I do not like the 4 year horizon because so many things can change, promo, stock price, etc. So I just looking at the next 1 to years. But if you like, do the 4 year estimation, but typically the first 2 is sufficient for you to see where you will make more in the next 2 years.
I’ve always thought TC should be defined in two different ways depending on the use case
when you’re comparing new offers to each other, you should use the direct on-paper value (sans stock appreciation, refreshers, one-time bonuses etc). but when comparing current job TC to new offers or outside of offer comparison, W-2-ish total TC is def relevant
