# How to budget a bonus before it lands

A bonus is pay with a date, not a windfall. Five steps to decide what it does — taxes, the gap it fills, the goal it funds — before the deposit shows up.

A bonus feels like found money because it arrives in one lump on a day that isn't payday. That feeling is the problem. Treated as a windfall, a bonus gets spent on the thing you happened to want that week. Treated as pay — pay that happens to arrive once — it funds the goal you have been under-saving for all year.

The steps below assume a target bonus you can estimate, paid on a known date. If your bonus is genuinely unpredictable, use the low end of what you've been paid before and treat anything above it as a second, smaller bonus when it arrives.

## Estimate the after-tax amount, not the headline

Bonuses are [supplemental wages](https://allocateai.io/glossary/supplemental-wages). Federal withholding on them is a flat 22% (2026, on the first $1 million), plus Social Security and Medicare, plus your state. Withholding is not the same as what you'll owe: if your marginal rate is 32%, the 22% withheld leaves a gap you'll settle at filing.

Rough rule: plan on keeping 60–70% of a bonus. A $20,000 target bonus is $12,000 to $14,000 you can actually direct. The [after-tax income calculator](https://allocateai.io/calculators/after-tax-income) handles a bonus on top of salary and shows the real number for your state and bracket.

## Write down the date and the number, and put it in the plan

The single most useful thing you can do is give the bonus a date. "March 15, about $13,000 after tax" turns it from a vague hope into an [expected income event](https://allocateai.io/glossary/expected-income-event) — something the rest of the plan can count on.

Once it has a date, goals can be sized around it. A house fund that needs $30,000 by next summer doesn't have to be saved at $2,500 a month if $13,000 of it arrives in March; it needs $1,400 a month plus the bonus. That is the difference between a plan you can keep and one you abandon by February.

## Fill the gap first, then the goal

Order matters. Before the bonus goes anywhere ambitious, check three things:

- **Any tax you'll owe on it beyond withholding.** Set that aside now; it isn't yours.
- **The [emergency fund](https://allocateai.io/glossary/emergency-fund).** If it's under three months of essentials, the bonus tops it up before anything else.
- **High-interest debt.** A card at 24% is a guaranteed 24% return when you pay it. Nothing you can buy beats that.

Whatever is left is the part that funds a goal — one goal, chosen in advance, not four goals chosen at the ATM.

## Decide the split in percentages, in advance

People who keep bonuses do it by deciding the split before the money arrives. A split that works for most:

| Bucket | Share | On $13,000 |
| --- | --- | --- |
| Tax set-aside (if withholding falls short) | 10% | $1,300 |
| Emergency fund top-up or debt | 30% | $3,900 |
| The one goal (house, wedding, index fund) | 50% | $6,500 |
| Spend it — on purpose | 10% | $1,300 |

The last row is not a joke. A bonus with 0% to enjoy gets raided; one with a planned 10% to spend does not.

## Move it the day it lands, and re-size the months after

Bonuses that sit in checking for a week become part of checking. Move each bucket the day the deposit clears. Then look at the months after: if the bonus funded half the house goal, the monthly contribution to that goal can drop, and that money can go somewhere else — or nowhere, if the plan was tight.

This is the part most people skip, and it's why a bonus so often feels like it changed nothing. It changed the goal; the monthly plan has to change with it.

## The plan, in Allocate

You'd say: "I'm getting about a $20,000 bonus on March 15. Put it toward the house fund." Allo-Bot would propose something like:

- Expected income: bonus, March 15, ~$13,200 after tax (22% federal, 6.2% + 1.45% FICA, 5% state).
- $1,000 set aside for tax owed beyond withholding, marked in the plan as not spendable.
- Emergency fund: $2,400 to bring it to three months of essentials.
- House fund: $8,500 on March 15; monthly contribution drops from $2,500 to $1,400 through June, and the goal's date holds at July.
- $1,300 to spend, unassigned.

Every line waits for your approval. Say "make the spend part $800" and the plan re-sizes; the morning brief on March 16 shows the deposit and what it funded.

## Frequently asked questions

### Should I use a bonus to pay off debt or invest?

If the debt's rate is above what you'd reasonably expect from investing — anything over roughly 7% — pay the debt; the return is guaranteed and the market's isn't. Below that, it's a judgment call, and splitting is fine.

### Why was so much tax taken out of my bonus?

Bonuses use flat supplemental withholding (22% federal in 2026) plus FICA and state, so the withholding is often higher than your paycheck's rate. If your marginal rate is under 22%, you'll get the difference back at filing; if it's higher, you may still owe more.

### Can I count a bonus in my budget before it's paid?

Count it with a date and a conservative number, and don't let goals depend on it landing early. If the bonus is discretionary or the company has missed before, plan on the low end and treat the rest as a second, smaller bonus.
