I have not saved a blasted thing. It was cheaper to smoke. Less toys. 
I'm so in the hole now, I will not see the light of day from this hobby until about 2021.
But then again, hobbies are supposed to be like that, right?![]()
My signature says @ 12 grand and I believe it with smokes 15 bucks for a 25 pack here and 2 of us smoking pack a day. I could easily say I've spent $2500 on my vape journey not including our 2 provari's and thats no where near the 12 grand we've been spending on smokes for years previous.
More than enough to make me wish I had done this 47+ years ago.
I saved my life. Nothing else matters.
I'd say I'm probably spending more on vaping than I did on smoking right now.
It goes away. I have easily spent a grand on vaping when i started. Trying all the juices to find my taste. Trying all sorts of mods to find the one that works the best for me. Buying a dozen spools of temco kanthal and all the batteries and such.
But its all initial investment. Short of keeping up with battery technology and the occasional mod i barely spend more than 20 - 30 dollars a month now. And its almost all on juices...
Vaping can VERY easily be a HOBBY as well. And thats a totally different kind of expense. If you find yourself constantly buying new attys and tips and mods cause you like it then its no longer really a part of your "how much am i saving smoking" budget. Its you now spending money on a hobby you enjoy. And i don't think that should necessarily be frowned upon. But i also think that the two types of expenses do deserve to be distinguished from one another.
