Making extra money sounds amazing until it actually hits your account and somehow just disappears into your regular life. I’ve made money outside of my regular paycheck in a bunch of different ways over the years, some worth it, some honestly not worth the time I put in. But now that I’m trying to aggressively pay off debt, I’ve been thinking a lot more about what I actually want that extra money to do.

If I make an extra $100, $300, or $500 this month, should all of it go toward debt? Should I keep some for myself? And does an extra $100 even move the needle when the debt number is this big? That’s what I wanted to actually sit down and figure out.

Should All of My Side Hustle Money Go Toward Debt?

My first instinct is always yes, obviously, throw all of it at the debt and keep it moving. But real life doesn’t really work that clean.

First I have to figure out how much of that money is even mine to spend. Depending on where it came from, I might need to set some aside for taxes, or there might be expenses tied to whatever I did to make it in the first place. I don’t want to get so excited about sending an extra $500 to a credit card that I end up creating a whole new problem for myself later.

After that it really comes down to what I decided the side hustle was for in the first place. Right now one of my biggest goals is getting rid of debt, so yeah, I want a good chunk of extra money going toward that. But I also don’t buy into the idea that every single dollar I make has to immediately vanish into a credit card payment. If I worked for it and want to keep a little for myself, I can do that.

Maybe I decide 80% goes to debt and I keep 20%. Maybe some months I send all of it. Maybe part of it needs to go back into whatever made me the money in the first place. What I don’t want is to make an extra $300, let it just sit in my checking account with no plan, and then two weeks later have no idea where the hell it went. That’s the part I’m actually trying to change.

How Much Side Hustle Income Should Go Toward Debt?

Honestly I don’t think there’s one percentage that works for everybody. If the money has expenses attached, those come out first. If I need to set aside for taxes, that’s not part of the debt-payment budget either. I’m only interested in what’s actually left after all that, and from there I like picking a percentage before the money even comes in.

So if 80% of my usable side hustle income goes toward debt, a $500 month means $400 to debt and $100 for me. A really good $1,000 month means $800 to debt. I’m not renegotiating with myself every single time money shows up, and I can always change the percentage if life changes. It’s not a blood oath, it’s just a plan for the money. What actually matters to me is making sure more income actually improves my situation instead of just becoming more money I casually spend. I don’t want to make an extra $500 a month and somehow start spending $500 more a month, because then I’m just doing more work to stay in the exact same place.

Does an Extra $100 a Month Actually Make a Difference?

This one’s hard to believe when your debt balance is high. When you owe a lot, $100 can feel almost insulting. You send it, the balance moves a little, and you still owe a ridiculous amount of money.

But $100 a month isn’t just $100. It’s another $1,200 a year toward debt. $250 a month is $3,000. $500 a month is $6,000. And that’s before you even factor in the interest you avoid by knocking the balance down sooner. I’m actually working on a separate post that breaks down exactly what an extra $100 a month can do to credit card debt because I want to get into the real numbers. But the short version is I don’t think smaller extra payments deserve to get dismissed just because they aren’t dramatic. If $100 is what I’ve got, I’m using the $100.

Which Debt Should Get the Extra Money?

This gets more complicated once you’ve got more than one balance staring back at you. One option is putting extra money toward whatever has the highest interest rate, the debt avalanche method, which mathematically saves you more in interest because you’re going after the most expensive debt first.

The other popular option is the debt snowball, going after the smallest balance first. I get the appeal of both honestly. There’s something really satisfying about wiping an entire balance off your life and losing a whole minimum payment. But watching a card with a ridiculous interest rate eat my money every month also makes me want to go after that one first.

What matters most to me is that the extra money has an actual destination. If I’ve decided Card A is the target, that’s where it goes until I have a real reason to change the plan. Otherwise it’s way too easy to throw $50 here, $75 there, $100 somewhere else, and never actually feel like anything is moving.

Is Working More to Pay Off Debt Actually Worth It?

This is probably the question I care about most. I already have a job. I already have a life. I don’t want my solution to debt to turn into working every waking hour until it’s gone.

There are only so many hours in a day, and extra work costs something even when it doesn’t show up on a bank statement. It costs time, sometimes sleep, sometimes weekends or time with people I actually want to be around. And depending on the hustle, there can be real expenses too. So I don’t think every opportunity to make extra money is automatically worth doing. If I spend ten hours on something to make $60 after expenses, I need to actually decide if that $60 was worth ten hours of my life. Sometimes the answer is still yes, maybe I really need the $60. But I want to know what I’m trading before I say yes to it.

The side hustles I’m most interested in now are the ones that either pay enough to make the time worth it, can grow without needing the same amount of my time forever, or actually fit into my life without making everything else miserable. I don’t want to pay off my debt by building a life I hate living. I want the extra work to get me closer to needing less extra work.

See What Your Side Hustle Could Actually Do to Your Debt

This is exactly why I made the Side-Hustle-to-Debt Calculator.

I wanted to be able to plug in my actual debt balance, interest rate, and current payment, and then ask a simple question: what happens if I add my side hustle money on top of that?

TRY THE SIDE-HUSTLE-TO-DEBT CALCULATOR

You put in how much extra you’re making and choose what percentage you actually want to send toward debt, so you’re not pretending you’re going to throw 100% of it at the balance if that’s just not realistic for you. The calculator compares your current payoff timeline to what could happen once you add that extra income in, so you can see roughly how many months you could shave off and how much interest you could avoid. And you can just play around with it. Try $100. Try $250. Try $500. Try whatever you’re actually making right now. That’s way more useful to me than someone just telling me to “make more money.” I want to know what the extra money is actually buying me.

I Want My Side Hustles to Buy Back My Future Income

This is really what it all comes down to for me. I obviously want to make more money. But I don’t want the only result of making more money to be that I can afford to spend more money. I want some of it to actually change my financial situation.

Every debt I eliminate is one less payment taking a chunk out of my regular paycheck. One less minimum payment. One less balance collecting interest. One less company I owe money to every single month. Eventually that means more of the money I already make actually belongs to me.

That’s what I want the side hustle to buy. Not another bill. Not a more expensive lifestyle that requires me to keep hustling forever.
