That's about double what we spend, except we support two people versus one. What's the breakdown?
Rent: 1800
Car: 865
Groceries: 600
Internet: 120
Cell phone: 145
Insurance: 220
Gym: 65
Gas: 50
Apple Music: 10
Amazon Prime: 10
Grooming: 100
Of those I could get rid of Amazon Prime and reduce grooming by 40%. But I don't think $50/month will make a material difference.
To me the items bolded above scream TO BE CUT BY 70-100%. I'll let others tackle the car, but that's obviously your biggest money suck machine.
Our family of three spent <$300/month on groceries pre-pandemic and we're up to ~$400/month now, and that's adding additional meals we didn't cook before plus more meat than usual (one of our vices). There are some great threads here and entire websites dedicated to enjoying healthy yet frugal food.
Internet may or may not be within your realm of control but seems absurdly high to me, especially considering you live in a city. There has GOT to be a better option- is there a lower speed that would satisfy your need to stream video/music and respond to email, etc? We don't get more than 45 Mbps and it works just fine for our household. Another idea is to negotiate a lower per-month bill with your ISP? I have an annual chat with customer service and it saves me $10/month, or $120/year. Takes about 10 minutes. Not a bad hourly rate.
Cell phone- that's outrageous. You have got to find a better plan and/or provider than that. Period. See forums on this topic for ideas.
Gym- you can buy a *really* nice set of weights if you put money into that. There are also plenty of free outdoor workout options. It's my understanding that this is one of your hobbies, so if you feel like you need to keep it, I guess that's OK, but find a way to negotiate that lower. Most gyms will offer a discount if you ask and/or decide to look elsewhere. IMHO if I was the kind to pay for a gym, I'd cap it at a solid $40/month.
And finally, grooming.... Yikes yikes yikes yikes. Yikes. What in lawd's name do you spend that much money on for your body? If it's anything cleansing related I have two words: BAR SOAP. If it's hair (more probable)... I understand guys like to get their hair cut more frequently than ladies like me but holy shit that's just way too much money. Many of us here just get a nice buzzer for like $30 and have their SO's help via a once-a-month buzz/trim. You are spending $1000 (ok, whatever that is in canadian $) a year on literally something that either grows back or can be cleaned with soap.
$1000 saved a year is a week-long getaway (or several if you're frugal about it).
$100/month is equal to something like $18,000 if you contributed that into an index fund and let it grow for ten years.
$100/month is enough to feed eight starving kids / buy six malaria nets / choose-your-own-impoverished-nation-analogy.
To me, it just seems like the epitome of consumer culture to spend that kind of money without much thought and care on something so frivolous as making a body look/smell/feel marginally different. Please do consider doing something that will benefit either yourself or others to a greater extent either now or in the future. Maybe I'm missing something but this one *really* blew my mind.
