The four kinds of spending
Why Carlo sorts money into rent, bills, month categories and year categories, and the 30/25/30/15 starting point.
Most budgets fail because they treat every expense as though it belongs in the same bucket. Real life does not work that way. Some costs arrive every month, some are bills, some are rent, and some are not really monthly at all: travel, clothes, gifts, medical surprises, electronics, holidays, furniture, car repairs. Those feel irregular, but across a year they are entirely predictable.
So Carlo sorts spending into four kinds, by how often it actually happens.
Rent is the roof over your head and usually the largest single expense. A healthy target is somewhere around 25 to 35 percent of take-home, with 30 as a reasonable default.
Bills are the recurring monthly obligations besides rent: utilities, phone, internet, insurance, subscriptions, car payments, loan minimums. Roughly 25 percent. The more of your income already committed here, the less freedom you have everywhere else.
Month categories are everyday life: groceries, restaurants, coffee, gas, transit, household supplies, entertainment, small personal purchases. About 30 percent. This is the part people think of first, and it is only one of the four. Try to fit everything into it and the budget eventually breaks. These are your month coins.
Year categories are the expenses that do not behave monthly even though they happen every year: travel, clothes, gifts, holidays, out-of-pocket medical, electronics, furniture, personal care, repairs, annual fees. About 15 percent. The mistake most people make is treating these as surprises. They are not surprises, they are annual expenses that arrive unevenly. These are your year coins.
A simple starting point, then: Rent 30, Bills 25, Month 30, Year 15, adding to all of your take-home. But when Carlo builds your budget it does not use the 30 percent average for rent. It starts from your actual rent and splits whatever remains across bills, month and year in the same proportions, so a higher rent leaves a smaller but still balanced plan for everything else. Carlo will never suggest a budget that goes over your income.
The percentages are a starting point rather than a verdict. A high-rent city, no car, or a big family all shift the mix, and you can change any amount whenever you like. What matters is the structure: every dollar sorted into the right time horizon. Budget this way and annual expenses stop feeling like emergencies. Clothes, gifts, medical costs, travel, repairs are not failures of discipline, they are part of the plan.
