You need to work out your entire budget for everything over a year and see if any changes can be made.
Our household with zero mortgage or childcare costs spent 27k last year to the Penny as we pay for everything on cards. It’s irrelevant what others spend because even someone on the exact wage with the exact same number of children will have deviations.
There are the big bills, housing, power, food and transport but the other stuff is where adjustments may be able to be made. Or maybe there is zero flexibility, everything is on bare essentials.
