I'm still a little confused about how regular payroll contributions affect things. I think one's yearly totals with contributions will be much greater than start of year amount, so not a true gain/loss type purely on trading/investments performance.
I think that is what's wrong with the PIP thing on the TSP.gov website, just doesn't make sense to me. I suppose one could subtract out DCA contributions for a better picture of actual gains, but that number will still be higher because some of the gains will be 'interest/dividends' on the additional contributions. How do other people handle that?
Maybe I'm just thinking too much (better than talking too much I guess) but I do that too.
What tracking sytems are other's using?
Any other's out there someone wants to share?
Burro, I just link my spreadsheet amounts to another worksheet to cut down on the input. i.e. dates, TSP totals, etc. and put in a simple formula to calculate return on my TSP account. Looks like (current account value-beginning account value) -total contributions year to date/ beginning account value. i.e. (10,000-5000)-3000= 2,000/5000 =40% return
One quirk, if you receive matching contributions you will have to decide whether that is part of your return or not. You can leave it in and your return% will be higher or take it out and your return will more closely represent what your actual earnings were. Enjoy!
