This is exactly right, I had a 1.5 hour each way commute before we switched to work from home last year. I calculated that I saved around AU$5000 a year just from not having to commute or buy food/coffee out let alone the massive time saved. Not to mention the reason I had such a long commute in the first place is that I chose to live further away from the city to save money and actually afford to buy a home.

Plus as you say the 15 hours a week I get back on average, is basically another part time job or contract work I could pick up if I really wanted to earn some more on top.
