Thanks for the thoughtful reply LC! Yeah - I don't have it in me at the moment to figure out exactly where the spending growth is coming from - $20k/yr of it is principle paydown on the mortgage - so not really spending, and $6k is part time daycare. Utilities are much more expensive than previous years, and more than anticipated.
I don't really have a "budget". I only pretend like I do... Really I just say "Woa that's a lot - let's not spend more than that! That's our budget." But...whatever
Literally the ONLY expensive thing that anyone could possible consider us having that is "above average" for the things we buy and do is this house that we live in. Everything else is ultra cheap and way below average in consumption for our income group...
Honestly I just know that we're so cheap and sensible from the 10 years prior of being cheap and sensible that I'm supremely confident that if $90-$100k is what we need to spend in a year, then I guess that's what it is! Obviously if we were not making as much money then I'd need to think long and hard about austerity, but fortunately that isn't the case.
Regarding RESPs - Firstly I can wait until they're 7 years old and then play catch-up with double contributions, and still get the whole grant. It's literally only $15k for two kids over 15 years, so I'm not really worked up about it either way. I guess more importantly though is that I feel I have too much networth already locked away in RRSP and pension accounts, and I'd rather consider my TFSAs as retirements accounts too. I can't see the next 5 years so clearly for our life plans, so I'd like to keep as much money available for whatever may come, specifically, the thought of just paying out the mortgage fully in 3.5 years once it's up. Lastly, I'm not so sure how I feel about giving the kids a free ride through college or not. I think it'll very much depend on how they're doing in life. I would likely lean more towards just giving them some small partial support through college, and then gifting them a big sum of money a bit later on. Obviously I don't know what I'm talking about yet (oldest kid is 2 lol) but the thought of having $200k in some RESP that my kids expect to be spent on them for schooling is something I'm a bit leary of. I knew a few kids like that when I was in university who were just flush with parental money flowing in, and I think it might've caused them more trouble than good honestly...
