Annual Bonus & AWS Calculator Singapore: What You Actually Take Home
Bonus month arrives. Your company announces 1.5 months. You do the mental maths — S$7,500, nice. Then the payslip appears and it says S$6,100. Nobody told you CPF was going to take S$1,400 of it.
This is not a mistake on the payslip. It is the Additional Wage (AW) CPF rule — and almost nobody explains it properly when they announce the bonus. The amount of CPF deducted depends on how much you have already earned this year, not just a flat percentage of your bonus. For some people, CPF takes a big chunk. For others, barely anything at all.
The calculator below shows you your exact cash figure. Enter your salary, how long you have worked this year, and your bonus — and it applies the correct CPF ceiling logic, not the simplified version most people assume.
Let’s find out what your bonus is actually worth.
In Singapore, your bonus is classified as an Additional Wage (AW) and is subject to CPF — but only up to the AW ceiling, which is S$102,000 minus your total Ordinary Wages earned this year. For most lower-to-mid-salary employees (under S$6,000/month), CPF applies to the full bonus at 20% employee rate. For higher earners, the ceiling can mean only part of the bonus attracts CPF — or none at all. A S$5,000 bonus on a S$5,000 salary costs S$1,000 in CPF. The same bonus on an S$8,000 salary may only cost S$1,000 or less, depending on how much of your ceiling is left. Use the calculator above for your exact number.
Calculate my bonus →Why Your Bonus Feels Lower Than Announced
Three things cause the gap between the bonus your company announces and the cash that arrives in your bank account.
First, employee CPF is deducted. Just like your monthly salary, your bonus is subject to CPF — you contribute 20% (for employees aged 55 and below), which is taken off before you receive the money. Your employer also contributes 17% on top, but that goes into your CPF accounts, not to you in cash.
Second, people calculate from gross. When HR says “one month bonus,” they mean one month of your gross salary. If your gross is S$6,000, the bonus is S$6,000. What you receive is S$6,000 minus CPF — approximately S$4,800.
Third, the CPF ceiling can make the calculation unpredictable. Depending on your salary and how long you have worked this year, CPF might apply to your full bonus, a portion of it, or none at all. Most people do not know which category they fall into until the payslip arrives.
When your company announces a bonus, always ask yourself: “Is this the gross figure?” It almost always is. Budget and plan from the after-CPF number, not the headline figure. For most Singapore employees below 55 on a full-year salary under S$8,000/month, the cash you receive is approximately 80% of your gross bonus.
How CPF Applies to Bonuses in Singapore
In CPF terminology, your regular monthly salary is classified as an Ordinary Wage (OW). Your bonus — whether it is a performance bonus, a year-end bonus, or an AWS (13th month) — is classified as an Additional Wage (AW).
Both OW and AW attract CPF contributions. But they are governed by different ceilings, which is why bonus CPF feels different from monthly salary CPF.
- Ordinary Wage ceiling: CPF is calculated on up to S$8,000 of your monthly salary. Anything above S$8,000/month does not attract OW CPF.
- Additional Wage ceiling: CPF applies to your bonus up to the AW ceiling, which is S$102,000 minus your total OW subject to CPF for the year.
The contribution rates are the same regardless of whether the payment is OW or AW — for Singapore Citizens and PRs aged 55 and below, the employee rate is 20% and the employer rate is 17%.
PR Year 1 employees pay 5% employee CPF on eligible bonuses. PR Year 2 employees pay 15%. PR Year 3 and beyond match Singapore Citizen rates at 20%. The AW ceiling calculation works the same way — it is based on the annual salary ceiling of S$102,000 minus total OW.
| CPF Status | Employee CPF | Employer CPF | Applies To |
|---|---|---|---|
| Singapore Citizen / PR Year 3+ | 20% | 17% | Portion within AW ceiling |
| PR Year 2 | 15% | 9% | Portion within AW ceiling |
| PR Year 1 | 5% | 4% | Portion within AW ceiling |
| Foreigner (EP/WP) | 0% | 0% | No CPF — full bonus in cash |

The AW Ceiling — The Part Nobody Explains
This is where most people’s understanding of bonus CPF breaks down. There is a cap on how much of your bonus attracts CPF — and that cap depends on what you have already earned this year.
The formula is simple once you see it:
AW Ceiling = S$102,000 − (your monthly CPF-subject salary × months worked this year)
Your monthly CPF-subject salary is the lower of your actual monthly gross or S$8,000 (the OW ceiling). Multiply that by the number of months you have worked in the calendar year. Subtract from S$102,000. Whatever remains is how much of your bonus can attract CPF.
If your bonus is below that remaining amount: full CPF applies.
If your bonus exceeds it: CPF only on the portion within the ceiling. The excess is paid to you in full, with zero CPF.
High earners who have already hit their ceiling get more cash from their bonus — but they have also been paying more CPF through the year via their OW contributions. The system is designed to cap total annual CPF contributions, not to give higher earners an advantage on bonuses specifically.
Let’s make this concrete. If you earn S$5,000/month and work the full year, your OW subject to CPF is S$5,000 × 12 = S$60,000. Your AW ceiling is S$102,000 − S$60,000 = S$42,000. Any bonus up to S$42,000 attracts full CPF.
If you earn S$8,000/month (OW capped at S$8,000) and work the full year, your OW subject to CPF is S$8,000 × 12 = S$96,000. Your AW ceiling is S$102,000 − S$96,000 = S$6,000. Only the first S$6,000 of your bonus attracts CPF. Everything above S$6,000 is paid in full cash.
Bonus vs CPF Deducted vs Cash Received
Here is what the numbers actually look like for two common salary levels, both working a full calendar year. Employee rate: 20% (Singapore Citizen, below 55).
| Gross Bonus | CPF Applies To | Employee CPF (20%) | Cash Received | Employer CPF (17%) |
|---|---|---|---|---|
| S$5,000 (1 month) | S$5,000 (full) | −S$1,000 | S$4,000 | +S$850 |
| S$10,000 (2 months) | S$10,000 (full) | −S$2,000 | S$8,000 | +S$1,700 |
| S$20,000 | S$20,000 (full) | −S$4,000 | S$16,000 | +S$3,400 |
| Gross Bonus | CPF Applies To | Employee CPF (20%) | Cash Received | Note |
|---|---|---|---|---|
| S$5,000 | S$5,000 (full, under ceil) | −S$1,000 | S$4,000 | Bonus below ceiling — full CPF |
| S$10,000 | S$6,000 only | −S$1,200 | S$8,800 | S$4,000 above ceiling — no CPF |
| S$16,000 (2 months) | S$6,000 only | −S$1,200 | S$14,800 | S$10,000 above ceiling — no CPF |
| S$20,000 | S$6,000 only | −S$1,200 | S$18,800 | S$14,000 above ceiling — no CPF |
Assumes Singapore Citizen, employee aged 55 and below, full calendar year worked (12 months), all figures rounded. Employer CPF shown in S$5k salary table only; it applies in both scenarios but does not affect cash received.
Notice what happens at S$8,000 salary: a S$10,000 bonus and a S$20,000 bonus both incur the same S$1,200 in employee CPF. The extra S$10,000 in the larger bonus arrives in full. This is the AW ceiling in action — it is not a mistake, it is correct CPF logic.
When Your Bonus Has Zero CPF Deducted
Yes, this is possible. If you have already hit the S$102,000 annual salary ceiling through your OW contributions and any earlier Additional Wage payments, your year-end bonus may attract zero CPF.
This typically happens when:
- You earned a mid-year performance bonus or commission that used up your AW ceiling
- You earn a very high salary — though note that OW contributions max out at S$8,000/month, so the maximum OW ceiling used per year through salary alone is S$96,000, always leaving S$6,000 AW ceiling unless an earlier AW used it
- You joined mid-year from a previous employer who has already been factoring into the same year’s ceiling (note: the AW ceiling is employer-specific — this is a nuance worth verifying with your employer’s payroll team)
If you worked for the same employer the whole year and received no other AW payments, your AW ceiling will be at least S$6,000 (for those at the S$8,000 OW cap) and potentially much more (for lower salaries). Most year-end bonuses will attract at least some CPF. The zero-CPF scenario is real but less common than people think.
AWS vs Performance Bonus — What Is the Difference?
Both the AWS (Annual Wage Supplement, commonly called the 13th month) and a performance bonus are classified as Additional Wages (AW) under CPF rules. From a CPF deduction perspective, they work identically — both are subject to the same AW ceiling calculation.
The practical differences are about predictability and amount, not CPF treatment.
| Feature | AWS (13th Month) | Performance Bonus |
|---|---|---|
| Amount | Fixed: 1 month of contractual salary | Variable: based on company and individual performance |
| Guaranteed? | Yes, if in employment contract | No — discretionary |
| CPF treatment | AW — subject to AW ceiling | AW — subject to AW ceiling |
| Tax treatment | Taxable income | Taxable income |
| Prorated? | Often prorated for partial year | Depends on company policy |
| Timing | Typically December or January | Varies — Q1 for previous year is common |
| CPF AW ceiling shared? | Yes — if both paid in same year, they share the S$102k ceiling | Yes — same ceiling applies |
If you receive both an AWS and a performance bonus in the same calendar year, they share the same AW ceiling. The AWS is usually paid first in December, which reduces the remaining ceiling for any bonus paid in the same month. If you receive your annual bonus in January of the following year, it starts with a fresh ceiling for that new calendar year.
Real Singapore Bonus Scenarios
Three scenarios that reflect how different salary levels and bonus sizes actually play out under 2026 CPF rules. All assume Singapore Citizen, below 55, full year employed.
Scenario 1: Fresh Graduate, S$3,500 Salary, 1-Month AWS
S$60,000 remaining
OW YTD: S$3,500 × 12 = S$42,000. Ceiling = S$102,000 − S$42,000 = S$60,000. Full CPF on entire S$3,500 bonus.
Employee: S$700
20% of S$3,500 = S$700 employee CPF. Employer adds S$595 into CPF separately.
S$2,800
80% of gross bonus. Effective cash: S$2,800. Not S$3,500 — this is the number to budget from.
Scenario 2: Mid-Career, S$5,000 Salary, 2-Month Performance Bonus
S$42,000 remaining
OW YTD: S$5,000 × 12 = S$60,000. Ceiling = S$42,000. Bonus of S$10,000 is well within ceiling — full CPF applies.
Employee: S$2,000
20% of S$10,000 = S$2,000 employee CPF. Employer contributes S$1,700 on top.
S$8,000
80% of gross bonus. The S$2,000 deducted is not gone — it goes into OA, SA, and MediSave.
Scenario 3: Higher Earner, S$8,000 Salary, 2-Month Bonus (S$16,000)
Only S$6,000 left
OW YTD: S$8,000 × 12 = S$96,000. Ceiling = S$6,000. CPF only on the first S$6,000 of the bonus.
Employee: S$1,200
20% of S$6,000 only = S$1,200. The remaining S$10,000 of the bonus has zero CPF deducted.
S$14,800
92.5% of gross bonus in cash. Effective rate is much lower than 20% because only S$6,000 attracted CPF.
Scenario 3 is the one that surprises people most. A higher earner gets a better effective cash percentage on their bonus than a lower earner — not because the rules favour them, but because they have already hit most of their annual CPF ceiling through monthly contributions.
| Profile | Gross Bonus | Employee CPF | Cash Received | Effective Cash % |
|---|---|---|---|---|
| S$3,500 salary, 1 month AWS | S$3,500 | S$700 | S$2,800 | 80.0% |
| S$5,000 salary, 2 month bonus | S$10,000 | S$2,000 | S$8,000 | 80.0% |
| S$8,000 salary, 2 month bonus | S$16,000 | S$1,200 | S$14,800 | 92.5% |

Calculate my real bonus amount →Common Mistakes Singaporeans Make About Bonus CPF
1. Planning With the Gross Bonus
The most common one. Someone hears “two months bonus” and immediately starts doing mental maths at full gross value. They set aside S$10,000 for a renovation deposit, then receive S$8,000 and feel short. The fix is simple: always calculate from the after-CPF figure first.
2. Assuming 20% Always Applies to the Full Bonus
Lower-salary employees: yes, often 20% applies to the full amount. Higher-salary employees: not necessarily. If your AW ceiling is S$6,000 and your bonus is S$15,000, you pay 20% on S$6,000 (S$1,200), not on the full S$15,000 (S$3,000). The effective deduction is 8%, not 20%.
3. Thinking CPF on Bonus Is Money Lost
The employee CPF deducted from your bonus goes into your OA, SA, and MediSave accounts. It earns interest (2.5%–4% p.a.). For many people, a significant portion will go toward housing via the OA, which they would have needed to save cash for anyway. It is deferred money, not lost money.
4. Not Accounting for Income Tax on the Bonus
CPF deduction is separate from income tax. Your bonus is taxable income in Singapore, but income tax is not deducted at source — it is assessed annually by IRAS. The CPF payslip number is your after-CPF cash. Income tax on the bonus comes later during tax season. Budget for both if your total income moves you into a higher tax bracket.
5. Confusing AWS and Bonus Ceiling When Both Are Paid in December
If your company pays both the AWS and a performance bonus in December, they both count as AW in the same month and share the same annual ceiling. Some companies spread payments — AWS in December, performance bonus in February — to give the bonus a fresh annual ceiling. If both arrive in December, understand that the ceiling is shared and your payroll team calculates the combined amount correctly.

Frequently Asked Questions
Yes — bonuses are classified as Additional Wages (AW) and are subject to CPF for Singapore Citizens and Permanent Residents. However, CPF only applies to the portion of your bonus that falls within the AW ceiling, which is S$102,000 minus your total Ordinary Wages subject to CPF for the year. The employee rate is 20% for those aged 55 and below, and the employer contributes 17% additionally. Foreigners on Employment Passes or Work Permits are generally not subject to CPF.
It depends on how much of your annual AW ceiling remains. If your bonus falls entirely within the ceiling, 20% is deducted (for Singapore Citizens aged 55 and below). If your bonus exceeds the ceiling, 20% applies only to the portion within the ceiling — the rest is paid in full with no CPF. For example, a S$10,000 bonus on a S$5,000/month full-year salary costs S$2,000 in CPF (full CPF, ceiling of S$42,000 remaining). The same bonus on an S$8,000/month full-year salary only costs S$1,200 in CPF (CPF on S$6,000 only — ceiling of S$6,000 remaining, S$4,000 above ceiling = no CPF).
Yes. The AWS is taxable income in Singapore and must be declared in your annual tax return to IRAS. However, income tax is not withheld at source in Singapore — you pay it annually based on your total assessable income. CPF is deducted from the AWS at time of payment (subject to the AW ceiling). Income tax is a separate calculation and is assessed by IRAS in the following year.
Your bonus is not subject to CPF when: (1) you are a foreigner on an Employment Pass or Work Permit; (2) the portion of your bonus exceeds your remaining AW ceiling (the excess above the ceiling attracts zero CPF); or (3) you have already used up your full annual AW ceiling through earlier Additional Wage payments in the same calendar year. The AW ceiling is S$102,000 minus your total Ordinary Wages subject to CPF for the year.
Yes — Permanent Residents pay CPF on bonuses at their applicable graduated rates. PR Year 1: employee 5%, employer 4%. PR Year 2: employee 15%, employer 9%. PR Year 3 and beyond: employee 20%, employer 17% (same as Singapore Citizens). The AW ceiling calculation is identical for PRs and Singapore Citizens — S$102,000 minus total OW subject to CPF for the year.
Yes. The annual CPF salary ceiling of S$102,000 resets on 1 January each year. So if you receive a bonus in January for the previous year’s performance, that bonus’s CPF ceiling is calculated based on your OW earned in the new calendar year, not the previous one — which typically means a much larger ceiling is available, and full CPF may apply. This is one reason some companies pay performance bonuses in early Q1 rather than late December.
Yes. If you receive a bonus or AWS upon leaving, CPF still applies based on the AW ceiling calculated from your OW at that employer for the months worked. The ceiling would typically be larger (since you have fewer months of OW deducted), meaning more of the bonus may attract full CPF. For example, if you worked 6 months at S$5,000/month and receive a S$5,000 departure bonus, your OW YTD is S$30,000, your AW ceiling is S$72,000, and the full bonus attracts CPF.
