How to calculate your day rate
Your day rate should cover your target annual income, plus account for non-billable time (holidays, sick days, admin), CPF (if applicable), and income tax. A common approach is to divide your target annual income by the number of billable working days (typically 220-240 days).
GST considerations
If your annual turnover exceeds S$1 million, you must register for GST and charge 9% on top of your day rate. Even if below the threshold, you can voluntarily register. GST collected must be remitted to IRAS quarterly.

How to calculate, negotiate, and understand tax on daily contractor rates
How do you work out a day rate from an annual salary?
Take your target annual income and divide by the number of billable working days. Most contractors in Singapore work around 220 to 230 days per year (52 weeks minus public holidays, leave, and non-billable time). If you want to earn S$120,000 per year, your day rate would be about S$522 to S$545 per day before tax.
Why is a day rate higher than the equivalent salary?
A contractor day rate needs to cover things an employer normally pays: CPF employer contributions, annual leave, sick leave, medical benefits, training, and insurance. You also need to cover gaps between contracts and your own admin time. As a rule of thumb, a contractor day rate should be 30% to 50% higher than the equivalent employee daily pay.
What is a typical day rate for contractors in Singapore?
Day rates vary widely by industry and skill level. IT contractors typically charge S$400 to S$1,200 per day. Finance and consulting professionals may charge S$500 to S$2,000+. Junior roles might be S$250 to S$400. The rate depends on demand, your experience, the contract length, and whether you work through an agency or directly with the client.
Do you need to charge GST on your day rate?
Only if you are GST-registered. You must register for GST if your taxable turnover exceeds S$1 million in the past 12 months. If registered, you add 9% GST on top of your day rate — so a S$500 day rate becomes S$545 on your invoice. Below the threshold, GST registration is voluntary.
How is your day rate income taxed?
Your total annual income from day rate work is taxed at progressive rates from 0% to 24%. You declare your gross income, deduct allowable business expenses, and pay tax on the net amount. If you earn S$150,000 net and claim S$20,000 in expenses, you are taxed on S$130,000. Your tax bill would be around S$10,700 (before reliefs).
Should you include CPF costs in your day rate calculation?
As a self-employed contractor, you must pay MediSave contributions but not full CPF. Factor MediSave into your rate — it costs about 8% to 10.5% of your net trade income (depending on age). If you want to voluntarily contribute to CPF for housing or retirement, add that cost too. Missing this step means you will under-price your services.
How do you handle days when you are not working?
Unlike employees, contractors do not get paid leave. Your day rate must cover non-billable days such as public holidays (11 per year in Singapore), sick days, holiday time, and gaps between contracts. If you plan to take 20 days of leave and budget 10 days for admin, that is 30 fewer billable days — factor this into your annual target.
