Frequently asked questions
Can I split unevenly, such as by usage?
Yes, enter each person's share as a percentage rather than splitting evenly, and the calculator adjusts each amount accordingly.
What if the percentages don't add to 100%?
The calculator scales the amounts so they always total the full bill, but shows a note if your entered shares don't sum to 100%.
Does this work for one-off bills like takeaway?
Yes, it works for any shared cost, not just recurring utility bills.
