Annual bonus or 13th month: how to use it wisely

A year-end bonus, a 13th-month salary or profit-sharing is a welcome boost. It is also one of the easiest sums to waste: because it arrives all at once, it feels like “extra” money, and a few weeks later little is left. The key is to decide what the bonus will do before it arrives.
Guaranteed or variable?
The first question is whether the bonus is certain.
- Guaranteed (a 13th month written in your contract, a fixed annual allowance): you can include it in your income by dividing it by 12. A $4,000 guaranteed bonus adds $333 to your monthly budget — but only if you set this amount aside each month until the bonus is paid, or if you use it to pay annual bills.
- Variable (performance bonus, commission, profit-sharing): never build your fixed expenses on it. Keep it outside the monthly budget and decide in advance how to split it. If it is lower than expected, or does not come, your budget does not suffer.
Our planner offers both options in step 1: “add it to my monthly budget (÷ 12)” or “keep it outside the monthly budget”, with a share sent to savings.
A simple order of priorities
- Expensive debts: if you have credit card or revolving credit debt at a high interest rate, paying it off is the best guaranteed return available.
- Emergency fund: complete it up to at least three months of essential expenses.
- Annual bills provision: if your sinking fund is behind — for example before a large insurance bill — fill the gap.
- Projects and long-term savings: car, home deposit, education, retirement.
- Treats: a planned share for pleasure, without guilt.
An example split
Lina expects a $4,000 bonus. Her emergency fund is complete, she has no expensive debts, and she wants to change her car in three years. She decides to keep 60% for savings and 40% for herself:
| Use | Share | Amount |
|---|---|---|
| Car project | 40% | $1,600 |
| Retirement savings | 20% | $800 |
| Holidays and treats | 40% | $1,600 |
She will enjoy $1,600 freely and still add $2,400 to her savings, which, in the planner, raises her average monthly savings by $200.
Put this into practice with your own figures.
Open the plannerWhy keep a share for pleasure?
Budgets that forbid every treat rarely last. Planning a share of the bonus for something you enjoy — a trip, a piece of equipment, a family outing — makes the rest of the plan easier to respect. What matters is that the share is chosen in advance, not discovered at the end of the month.
Practical tips
- Estimate prudently: use a net amount, after tax and contributions, and round it down if it is variable.
- Act on payday: transfer the savings share on the day the bonus arrives, before it mixes with your usual spending.
- Avoid lifestyle creep: do not commit to a new monthly expense (a bigger car loan, a more expensive subscription) on the strength of a variable bonus.
- Think about taxes: in some countries, bonuses can be paid into a retirement or company savings plan with tax advantages. Check the rules that apply to you.
Frequently asked questions on this topic
Should I use my bonus to repay a mortgage early?
It depends on the rate. Repaying a low-rate mortgage early brings a modest, guaranteed gain. If you have no emergency fund or still carry expensive consumer debt, those come first. Also check whether your loan charges early repayment fees.
What if my bonus is paid in shares?
Treat shares as variable income: their value can change before you sell them. Many advisers suggest not keeping too large a share of your savings in your employer's stock, since your salary already depends on the same company.
How do I avoid spending the bonus without noticing?
Move it the day it arrives: transfer the savings share to its accounts, and put the pleasure share in a separate sub-account. When the pleasure account is empty, the bonus is spent as planned.
Good to know — In the planner, try both options — spread over 12 months and kept aside — to see how much your monthly savings change. It is a quick way to decide which approach suits you.
And if there is no bonus this year?
If your budget was built without it, nothing changes in your daily life: only your projects are delayed. That is the best argument for treating variable bonuses as a bonus — and not as part of the salary you live on.
