I keep it pretty simple, and rather than set yearly goals, I set a retirement goal and check in to see how I'm tracking to that. Quite a few years ago, I set a retirement goal X years down the road (at the time, ~20 years). And I tallied up what we were saving at the time, and put that into a spreadsheet. Then I just did a very simple compounding formula and dragged it down, so each row was one month of time, with one month of contributions adding in and growth going up each month. (I used an 8% annual rate.)
So it's a dead simple linear growth rate, with an assumed savings rate, that ends the year and month I want to retire with the amount I think I'll need. I then labeled each row with the month and year they represented. That's the 'line' I want my retirement savings to hug to, if not exceed. At the end of each quarter, I add up what I have (which I track monthly, but only do this comparison quarterly), and record that next to the target for that month. I can then tell whether I'm doing better or worse than my goal.
Over the years, the amount we've saved each month has gone up, and returns are obviously very lumpy, but I've left the projection file untouched. I figure, if I'm saving more that just means I'll be ahead of the curve. Right now I'm tracking to end a few years ahead of our retirement goal. So I can either retire early, or on schedule but with a bigger savings. Still a long ways to go, though, so we're just plugging away. (This year will be a less than awesome comparison point.)
