Paying yourself a salary from a buffer

Income smoothing uses two accounts: every payment lands in a buffer account, the tax share leaves it the day the money arrives, and on the 1st of each month a fixed salary moves from the buffer to the spending card.

A self-paid salary starts from one ceiling: what the year actually leaves after taxes. Take the gross year, subtract the year's taxes, and divide by twelve.

Dana earned 430,000 UAH and paid 48,628.08 in taxes, so 430,000 − 48,628.08 = 381,371.92 is hers for the year, or 381,371.92 / 12 = 31,780.99 UAH a month. That is the most she could pay herself if every year were average.

A salary set at the ceiling leaves no room for a weaker year; a salary set below it builds a margin. So the net average is where the decision starts, not where it ends — the next step is to choose how far below it the salary should sit.

A buffer rises in good months and falls in thin ones; the summer is the test. To see what the summer costs, read the buffer balance at the end of May and at the end of August and take the difference.

On Dana's plan the buffer ends May at 78,501.28 UAH and August at 41,434.26, so the summer drains 78,501.28 − 41,434.26 = 37,067.02. Month by month the drawdown is the salary minus what the month earned after taxes: June −8,282.34, July −15,802.34, August −12,982.34.

The point of the plan is to prove, before the summer arrives, that the buffer is big enough to cover it. If the lowest balance of the year stays above zero, the salary is safe on this forecast.

It is tempting to pay yourself the highest salary the forecast allows — here 31,766.75 UAH, which brings the buffer to exactly zero at the end of August. But that only holds if next year repeats last year exactly, lesson for lesson.

It won't. A reasonable stress test is a year 20% weaker across the board: after taxes that leaves 25,044.33 a month on average, and even a 28,000 salary drains 35,468.08 from the buffer over the year. At 31,766.75 the buffer would run dry long before September.

So the margin between the salary and the ceiling is not timidity; it is what lets a bad year be survived without a panic cut mid-year. Set the salary low enough that a weaker year is uncomfortable, not catastrophic.

By late spring the buffer holds its yearly peak, and not all of it is needed for smoothing. Split that peak into two parts: what the thin months will draw, and the surplus above it.

At the end of May Dana's buffer is 78,501.28 UAH. The summer will draw 37,067.02, so 78,501.28 − 37,067.02 = 41,434.26 is surplus — exactly the balance left at the end of August. That surplus has done its smoothing job and can move to the cushion, the separate account that protects against emergencies, keeping only a little back for a weak September.

Two accounts, two jobs: the buffer smooths the known seasonal dip; the cushion protects against the unknown. Money that smoothing no longer needs is free to protect.

Check the buffer against the plan about once a quarter. When it falls behind, the rule is small and early: a little cut now beats a big cut later.

If by April the buffer is 15,000 UAH behind, cutting the salary by 1,500 a month wins the gap back over ten months (1,500 × 10), almost unnoticed. Three wrong moves: hoping the summer beats last year repeats the March mistake; stopping the salary breaks the essentials it is meant to cover; borrowing from the tax account spends money that belongs to the state.

A raise has a stricter bar: only after a full year that ends with the buffer higher than it started, never off one good month. Two reviews a year, in April and October, are enough.
