The 4 ways couples split money. And why all of them kinda suck.

The 4 ways couples split money. And why all of them kinda suck.

The Classic "50/50" Split

Rent? 50/50. Groceries? 50/50. Everything? 50/50.

Sounds fair until you realize one of you is broke every month while the other one's stacking savings. 50/50 is for roommates. You're building a life together.


The vibe: Roommates splitting a lease. Not partners building a life.

The "Everything's Ours" Approach

The "You Pay This, I'll Pay That" System

The "Whoever Gets It" Method

None of these approaches are wrong they just don't account for income disparity. When one partner earns more, equal contributions aren't actually fair. That's where proportional splitting changes everything.

There's a better way

You don't have to merge everything. You don't have to keep fighting. You need a way to split expenses that actually makes sense for your life.

That's KUPPL.

What KUPPL Actually Does

What KUPPL Actually Does

No spreadsheets. No awkward conversations. No guilt. Just clear, automatic fairness.

Split Fair, Not Equal

Split Fair, Not Equal

Stop splitting 50/50 when you don't earn 50/50.

You make $50K, they make $85K? You pay 37%. They pay 63%. One partner isn't drowning. The other isn't resented. That's the point.

Why Proportional Splitting Saves Relationships

Why Proportional Splitting Saves Relationships

Money problems aren't really about money. They're about fairness. Trust. Feeling like equals—even when your paychecks aren't.

76% of Couples Fight About Money

It's the #1 thing couples fight about. And when one of you is stretched thin while the other's comfortable? That's where resentment starts. KUPPL fixes the math before it breaks the relationship.

Financial Arguments Predict Divorce

Money fights don't blow over. They build up. And couples who fight about money frequently are far more likely to split. Fair finances aren't a nice-to-have—they're protective.

67% of Couples Have Income Disparities

Two-thirds of couples have income gaps. Almost all of them split 50/50 anyway. No wonder it feels off. KUPPL matches your split to your actual life.

Why I Built KUPPL

Why I Built KUPPL

Money was always an issue. My partner and I earned different salaries, and no matter what we tried 50/50 splits, alternating payments, apps that promised to fix this something always felt off. The resentment crept in with every rent check, every dinner out, every conversation about who owed who. When we found out our daughter was coming, I realized we couldn't keep living like this. Our home needed to be a calm haven, not a place where love got buried under spreadsheets and IOUs.


I spent endless nights researching, building, and rebuilding an Excel template until it finally worked. One night, over cocktails, I presented it to my wife. We chose our joint expenses together, laughed, planned, and for the first time in years it was fun. No stress. No anger. Just the pure feeling of building something together.


That's KUPPL. The system that saved my relationship—built for every couple who's tried everything and finally gets that fair doesn't mean equal.

KUPPL is built for couples who:

Earn different salaries and are tired of splits that don't feel fair

Want to plan for life's big moments together—not fight over who pays what

Believe partnership means equity, not keeping score

Are ready to turn money conversations from stress into strategy

We're launching soon, and I'm looking for our founding couples. Join the waitlist now and you'll lock in lifetime founding pricing a thank you for believing in what we're building before anyone else. Let's get you KUPPLd.
