Thanks for some feedback, everyone.
After sleeping on it, I've chilled out a bit. Still, I feel stupid for engaging in some serious lifestyle creep.
Here's some comments, in turn:
All is not lost. You still have a much higher savings rate than the typical American, and a desire to improve. Use that.
seattlecyclone: your practical tips are good, but I like this better. I tend to get hung up on things I can't do anything about. I need the reminder to fix what I can fix.
you might seriously consider switching to spending cash
We're going to take September and track everything. If we still don't like our results, we'll go with a cash only system.
How does your wife feel about the situation?
Excellent question. In general, she's more frugal than me. Right now, she recognizes we've both been spending pretty indiscriminately. We're on the same page and she's totally amazing.
Was it something you bought, something you did, or something you ate? That's where money tends to go.
What is it that you think caused you to backslide? Don't blame it on Mint. Mint is just a tracker. You made the decision to go to the store and swipe the card.
Short answer: I just don't know. I'll have to get serious about organizing the records. I think it's a combo of no explicit goal, lifestyle creep, buying a (modest) house (25k down on a 120k house), home renovations (7k), having a child (3k?), travel (ehh, 8k?).
Was it Mint's fault? No. It was ours. Which is nice, because that means we can fix it.
I really like Personal Capital for tracking.
Look forward to hearing the results of your analysis. Is it lifestyle creep or more structural?
Good luck!
I'll look into Personal Capital.
How would you divide between lifestyle creep and structural?
Clip a stiff piece of paper to the card with the amount on it.
This is a great, practical tip. Thanks!
If you want to increase your savings rate to a really high number, the savings rate needs to come first and optional spending second.
What pisses me off is that we knew that and were implementing it 3 years ago. We just got lazy. That's embarrassing.
Decide how much you want to save, arrange automatic deposits/transfers for it each pay cheque and live off the rest.
I love the simplicity, and I think we're going to head this route. We've got a lot of possessions that I'm starting to feel seriously weighed down by. I think an aggressive savings rate will cut out our buying of bullshit.
