Where does my money go every month?

Usually one of two things, and the result separates them. Either the committed side — bills, debt minimums, planned savings — is bigger than it looks when the pieces are listed one at a time, or the month is absorbing expenses that arrive once a year instead of once a month. The annual irregulars field exists to make the second one visible: a $3,000 year of car repairs, gifts, and premiums is $250 a month whether or not anything has been set aside for it.

There is no universal number, and this calculator does not publish one as a target. What it does is draw a line at 10% of take-home pay: at or above that, the month reads as room, because the leftover is big enough to survive a normal-sized surprise. Above zero but under 10% reads as tight, and below zero reads as short. Those are Whatify planning bands for reading one month, not a savings-rate recommendation.

It depends entirely on the size of the fixed side, which is the one thing the rule cannot see. The 50/30/20 split assumes needs fit inside half of income, and in an expensive metro a single housing payment can pass 50% before groceries or transport are counted — at which point the rule reads as a verdict rather than as a description. This scenario applies no percentage targets. It subtracts real amounts and reports what's left, so a household spending 62% on needs and still landing with room isn't graded against a split it was never going to hit.

A larger paycheck usually arrives with a larger committed side: a bigger housing payment, a car payment, more subscriptions, higher planned savings. The unassigned amount at the end can sit flat while income climbs. Irregular expenses scale too — two cars, a longer travel list, and more gift occasions make for a bigger annual number to divide by twelve. Entering the real amounts tends to show whether the month is short on income or simply fully spoken for, which are different problems with different fixes.

Biweekly pay usually delivers 26 paychecks a year, though some calendar years and payroll schedules produce 27. Twenty-four of the 26 cover the usual two-per-month rhythm; the other two land in the months that happen to catch a third pay date. Each biweekly check is annual take-home divided by 26, so those two extra checks are worth a little under one monthly average across the year — an amount a monthly budget averages into the background where nobody can see it. This scenario names it whenever the pay cadence is biweekly, and deliberately leaves it out of the landing, which is meant to describe an ordinary month.

The scenario asks for an annual total rather than a monthly one, because that is how these expenses are easier to recall: last year's car repairs, holiday and birthday gifts, travel, annual insurance premiums, deductibles, vet visits, home maintenance. Add them into one number and the result divides by twelve to get the monthly set-aside. A rough estimate is far more useful here than a zero, and leaving the field at zero is flagged in the result as a stated assumption rather than a fact about the year.

No. There is no bank connection, no transaction import, and no category tracking, and nothing is read from an account. You type the numbers, which takes about five minutes and works as well from a careful estimate as from an exported statement. The tradeoff is deliberate: this is a read on where the month lands, not a ledger of where it went.

A fixed bill arrives on a schedule at an amount you don't decide month to month — rent or mortgage, utilities, insurance, phone, subscriptions. Flexible spending is the part where the amount is a choice: groceries, restaurants, fuel and rides, entertainment, shopping. Debt minimums get their own field so they stay separate from the rest of the bills and can carry over into the debt scenarios. The split matters because the steadied month trims the flexible bucket and nothing else.

Here they come out before the landing, alongside the bills, so the landing is what remains after paying yourself. That makes the landing smaller than the balance sitting in checking, on purpose — a transfer you already make is spoken for. The 12-month reserves line credits it back, which is why a month that lands tight can still show reserves growing. Contributions withheld from a paycheck, such as a 401(k), are already out of take-home pay and are not entered again.
