"We used to argue about money every month. Now we just add expenses to Bill Split Pro and everything is crystal clear. Best relationship decision we made."
Common questions about splitting expenses as a couple.
There's no one-size-fits-all answer. Some couples prefer 50/50 for simplicity, while others split proportionally by income (e.g., 70/30 if one earns significantly more). Bill Split Pro supports both methods- you decide what's fair for your relationship.
Add all expenses under the partner who paid, then split them according to your agreement. Bill Split Pro will calculate the balance and show exactly how much one partner owes the other at the end of the month.
Most couples split shared living costs like rent, utilities, groceries, and household supplies. Date nights and entertainment can go either way. Personal expenses like individual subscriptions, clothing, or hobbies are typically kept separate. Discuss and decide what works for your relationship.
