Pre-assigning a bonus you already know is coming
Advice about bonuses is nearly always written for the moment the money lands, which is the worst moment to decide anything. If your bonus, thirteenth-month payment or annual profit share arrives on a predictable date, you can assign it weeks in advance while nothing is tempting you. This page covers how to plan an amount that is not guaranteed, the order to fill envelopes in, and the one line item most people forget: the part that is meant to be spent.
A dated bonus is not a windfall
There is a real difference between money you did not expect and money you expected but had not received. A found note in a coat pocket is a windfall. A thirteenth-month payment that lands every December, a profit share that follows the annual results, a fixed contractual bonus in March — those are income with a date, and treating them as windfalls is what makes them evaporate. The practical consequence is that you can budget them the way you budget a paycheck: by deciding where they go before they exist. The decision made in October about December's money is almost always better than the one made in December, because in October nothing is in front of you and nobody is waiting.
Plan the amount you are confident about, not the amount you hope for
Most bonuses are not fully guaranteed, which is the reason people give for not planning them. The fix is to split the number rather than skip the exercise. Write down the amount you would be very surprised not to receive — for a contractual thirteenth month that is the whole thing, for a discretionary bonus it might be the lowest figure of the last three years, and for a first year at a company it may honestly be zero. Assign that conservative amount now, in full. Anything above it gets assigned in one sitting on the day it lands, using the same order you already wrote down. You are never planning money that does not exist, and you are also never staring at a five-figure transfer with no plan.
An order that survives contact with the actual payment
Decide the sequence in advance and write it where you will see it. A defensible order for most people: first, anything already borrowed against the bonus, because the interest is running now. Second, the gaps that made this year hard — the annual-cost envelopes that were never funded properly, so next year's insurance and inspection do not need a bonus at all. Third, the emergency fund up to whatever level you decided is enough. Fourth, the long goal you would otherwise never make progress on. What matters is less the exact order than the fact that it was written before the money arrived; an order chosen on the day gets rearranged by whatever you happened to be browsing that week.
Assign a spending share on purpose
Give a named share of the bonus to something you simply want, decide it in advance, and make it a real number rather than a leftover. This is not a reward for good behaviour, it is what keeps the plan intact. A bonus assigned one hundred per cent to debt and savings is a plan people abandon in the shop, and abandoning it does not cost you the ten per cent you were tempted by — it costs the whole allocation, because once the order breaks nobody rebuilds it. Ten or twenty per cent, in its own envelope, spent without guilt, protects the other eighty. If you are tempted to skip this section, notice that the last time you received a bonus you probably spent some of it anyway; the only difference is whether it was decided or discovered.
What to do with the tax question
Bonuses are frequently taxed or withheld differently from regular pay, and the figure quoted to you may not be the figure that reaches your account. Do not plan against the gross number and do not try to model the deduction from a rule you read somewhere, because the rules differ by country, by employer and by the rest of your year. Get the net figure the reliable way: ask payroll what a bonus of that size nets, or look at the payslip from the last time you received one. If neither is available, assign only the portion you are sure of and hold the remainder unassigned until the payslip arrives. An envelope plan built on a gross figure fails on day one, and it fails in the most demoralising way — by being short of a number you already announced to yourself.
Common questions
My bonus is genuinely unpredictable. Is there anything to plan?
Plan the order, not the amount. The work that makes a bonus useful is deciding the sequence — what gets paid, filled or funded first — and that sequence does not depend on knowing the number. Write it down once and it will serve every bonus you ever receive, including the ones that turn out smaller than you hoped, because a smaller amount simply stops further down the list. If the amount is unpredictable and the date is too, keep the list somewhere you will find it under time pressure, which usually means in the budget app rather than in a note you will not think to open.
Should the whole bonus go to debt?
Usually not the whole thing, for two reasons that have nothing to do with the arithmetic. The first is the spending share above: a plan with no room in it tends to be abandoned wholesale rather than trimmed. The second is that clearing debt while the annual-cost envelopes are still empty often recreates the debt, because the next insurance renewal has nowhere to come from except the card you just paid off. Funding the certain future costs first can beat paying more off today, even when the interest maths says otherwise, because it removes the mechanism that produced the balance.
When exactly should I do the planning?
Far enough out that the money is abstract, close enough that your situation is current. Three to six weeks before the expected date works for most people. Earlier than that and the plan is made against a life you may not still be living; later and you are already thinking about what you will buy. Put a reminder in the calendar at the same time each year rather than relying on remembering, because the years you most need the plan are the ones where something else is going on.
