How to Calculate Salary Increment in Singapore: A Step-by-Step Guide
Shows the new salary after a percentage raise and how much more you earn per year.
In Singapore, payslip maths decides how much you can save, invest and spend, and CPF takes a sizeable share before the money reaches your bank account. Knowing the numbers in advance makes salary negotiations, job switches and budgeting far less of a guess.
What you need
- Current monthly salary (S$)
- Increment (%)
Step by step
- Enter the current monthly salary (S$).
- Enter the increment (%).
- The results update as you type, or press Calculate.
- Read the new monthly salary first, then the supporting figures below it.
The formula
New salary = current salary × (1 + increment ÷ 100).
Worked example
For example, with these inputs:
- Current monthly salary (S$): 4,500
- Increment (%): 5
the calculator returns:
- New monthly salary: S$4,725.00
- Monthly increase: S$225.00
- Annual increase (12 months): S$2,700.00
A second example
Now change the inputs to:
- Current monthly salary (S$): 5,625
- Increment (%): 5
the calculator returns:
- New monthly salary: S$5,906.25
- Monthly increase: S$281.25
- Annual increase (12 months): S$3,375.00
Practical tips
- Overtime eligibility depends on your salary and role under Part IV of the Employment Act, not just your job title.
- First- and second-year PRs contribute at graduated rates unless they opt in to full rates, so their figures will be lower.
- Keep a copy of your payslips: MOM requires employers to issue itemised payslips, which makes checking deductions easy.
- Remember the S$8,000 monthly Ordinary Wage ceiling from January 2026: salary above it does not attract CPF.
Background
CPF distinguishes between ordinary wages, which are paid for work in the month such as basic salary and fixed allowances, and additional wages, such as annual bonuses and leave encashment. Ordinary wages are capped at S$8,000 a month from January 2026, while additional wages are capped by an annual ceiling of S$102,000 minus the ordinary wages already subject to CPF in the year.
Total compensation in Singapore is more than the number on your offer letter. Employer CPF, variable bonuses, the Annual Wage Supplement (often called the 13th month) and benefits all add value, and comparing offers on take-home pay alone can hide meaningful differences.
The Employment Act sets out how hourly and daily rates are calculated for overtime, public holiday work and salary deductions. These formulas use the monthly basic rate of pay rather than gross salary, which is why the numbers can look lower than a simple division of your salary by hours worked.
