Splitting a birthday gift should be simple math, but for one woman, it turned into a much deeper conversation about years of financial imbalance within her family.

She and her younger sister agreed to go in together on a $400 pair of gold earrings for their mom’s 50th birthday, and she proposed a 60/40 split in her sister’s favor, offering to pay $250 while her sister covered $150, a gesture rooted in the fact that she earns significantly more.

Her sister pushed back, insisting she should only pay around $90–$95 instead, leaving the rest for her sibling to absorb.

That disagreement spiraled into a larger argument touching on their father’s financial support, roughly $15,000 over five years for college courses her sister eventually dropped, compared to the zero financial help she received after turning 18.

Even after conceding some ground, she’s left wondering why she’s consistently expected to pay more simply because she earns more.

AITA for not paying more money for a gift to our mom 50th birthday?

It’s my mom’s 50th birthday, and my sister and I agreed to chip in for a gift.

My sister found a pair of gold earrings for about $400. I thought it was a cool idea and proposed a 60/40 split, meaning I would pay $250 and she would pay $150. I suggested this because I know she earns less than I do and I wanted to help out.

But this proposal still wasn’t enough for her sibling.

However, she pointed out that I make significantly more than her and proposed paying only $90–$95, leaving me to cover the rest. I disagreed.

She is 23 and I’m 28. I make around $5,500 a month on a good month, while she earns about $1,800–$2,000.

The two siblings proceed to squabble back and forth.

We had a long argument about this. She insists she should pay much less than me. I brought up the fact that she’s an adult and that I’ve always paid more for things in the past.

She reminds her sister that she’s received special support in the past.

I also pointed out that after she turned 18, our dad supported her a lot with her choices, like paying around $15k over 5 years for university courses she ended up dropping out of. In contrast, I received literally zero financial support after turning 18.

Now the whole thing is making her second-guess herself.

After the argument, I felt like an AH.

Honestly, it’s not even about the money, even though I’m currently saving for an apartment. It wouldn’t break the bank for me to pay more, but it feels like this always happens, not just with my sister, but with my parents too (though I don’t mind it as much with them because I feel I owe them).

It just bothers me that everyone expects me to pay more simply because I earn more.

It’s never good to hold unfair expectations of the people around you.

Her sibling should have brought up her financial concerns at the very start.

At this point, it’s probably best to consider separate gifts.

This woman had already generously adjusted the split in her sister’s favor before any argument even started, which makes her sibling’s pushback for an even smaller contribution feel even less like a fair ask.

It’s clear her siblings have an entitlement problem, and only just now are the two beginning to contend with years of resentment about money.

Feeling guilty afterward doesn’t erase the legitimate frustration underneath; being the one who earns more shouldn’t automatically mean being the one who’s expected to give the most every single time.

There’s a difference between being generous and being treated as the default financial safety net.
