At least 30% per month, and aiming to go as much as 50% per month by reducing bills.
No debt, car paid off.
If I cut out fast food down to once a week, I'd save an easy $50 per month.
Switching car insurance for a $30 per month saving.
And I can save another $30 per month switching to Freedom Mobile as they have a good $35/month plan for my iPhone.
I value aggressive saving, frugality, minimalism, contentment, etc. and it doesn't even feel like I'm giving up anything. Not giving in to a pizza night because a) my wallet, and b) I want an aesthetic physique, which is also good for the wallet, and car mods are better than most of the food at restaurants anyway.
