How road tax in Singapore is calculated
Singapore road tax for a petrol car is a formula based on engine capacity in cc, billed every six months. Larger engines pay progressively more.
Cars over ten years old pay escalation surcharges, and electric cars pay by power rating plus a flat component. The calculator uses engine-cc bands. Estimate, not advice.

| Inputs | |
|---|---|
| Engine capacity (cc) | 1,598 |
| Vehicle age (years) | 3 |
| Computed by the engine | |
| Base 6-monthly road tax ✓ pinned | 370.86 SGD |
| Age surcharge ✓ pinned | 0 |
| 6-monthly payable ✓ pinned | 370.86 SGD |
| Annual road tax ✓ pinned | 741.72 SGD |
Every computed row comes from the engine, run on the inputs above. Rows marked ✓ pinned are also fixed by a published self-test, so a change to the model that moved them would fail its own tests.
