Many car owners still use the manual method to calculate roadtax rates, even though Malaysia now has a roadtax calculator that can automatically calculate the exact amount. But the question is — which one is actually more accurate and worth using?
Let’s compare both methods.
1. Manual Method – Traditional but Complicated
The manual method is still used by some car owners, especially when they just want an early estimate. Usually, they refer to the JPJ roadtax rate table based on:
- Type of vehicle (private, commercial, 4WD)
- Engine capacity (cc)
- Registration region (Peninsular Malaysia, Sabah, Sarawak)
The problem is, the formula is quite complex. For example, when reaching the maximum engine capacity, the rate increase according to the engine block itself, small mistake can lead to big issues in calculations.
2. Roadtax Calculator – Accurate & Time-Saving
Online calculators (such as on Bjak) use updated data from JPJ and insurers to generate automatic calculations. You only need to enter your number plate — the system instantly shows the exact rate without manual work.
Advantages:
- Accurate according to current JPJ rates
- Can check insurance prices at the same time
- No risk of miscalculation
- Results appear within seconds
Additionally, platforms like Bjak also allow you to renew insurance and roadtax together, so you don’t have to switch websites.
3. Accuracy: JPJ Data vs Manual
Modern roadtax calculators are directly connected to JPJ’s database — every calculation follows the same official rate used by JPJ officers.
Meanwhile, manual methods rely on individual references, which might use outdated or incorrect formulas.
Conclusion:
- In terms of accuracy and convenience, online calculators clearly win.
- For learning purposes, manual methods help you understand the basics — but they’re not practical for most people.
