Good day.

Under what term can I find studies/suggestions of which percentages of a daily (or monthly) income is supposed to be enough for expenses of food, fuel, electricity, car payment, insurance, entertainment, housing, medicines, savings, clothing... all the costs of daily living for a 'normal' ideal life (no luxury, no hardship) ?

Example: A 'normal' income budget should keep up with housing cost under 30% , car payment under 10%, electric bill under 8%, food under 6% , savings ideally over 10%, insurance under 4%, and so on.

Any suggestions how to/where to look ?

Recommended budget percentage, maybe? Or budgeting guidelines?

But some numbers don’t translate well to that; some things cost what they cost, and you can’t do with e.g. less food or less heat if your income drops. (also, food under 6%? US median income is around $80k, which would be $400 a month for food. An average family of four spends at least twice that) There’s some point as income rises where you have disposable income, can add discretionary expenditures, and other percentages drop.
