How many budget categories should a family have
Most families do well with somewhere between 12 and 20 categories — enough to give meaningful visibility without becoming a bookkeeping project. Start by separating fixed costs like rent and insurance from variable needs like groceries and fuel, then add lines for irregular expenses like car maintenance or school fees. If two categories always move together and you never look at one separately, merge them. The right number is whatever lets you spot a problem category at a glance; if you have to do math to figure out where the money went, you have too few.
