AA Rates Per KM 2018 Calculator
Calculate your vehicle’s cost per kilometer based on the 2018 AA rates for South Africa
Comprehensive Guide to AA Rates Per KM 2018 in South Africa
The Automobile Association (AA) of South Africa publishes annual rates per kilometer to help motorists and businesses calculate the true cost of vehicle ownership. The 2018 rates provide valuable insights into the financial implications of driving different vehicle types under various conditions.
Understanding the AA Rates Per KM
The AA rates per kilometer are calculated based on several key factors:
- Vehicle Type: Different vehicle categories (small, medium, large, luxury, 4×4) have different cost structures
- Fuel Consumption: Measured in liters per 100km, this directly impacts your fuel costs
- Fuel Price: Fluctuating fuel prices significantly affect your cost per kilometer
- Maintenance Costs: Regular servicing and unexpected repairs contribute to the total cost
- Insurance Premiums: Comprehensive insurance is a major component of vehicle ownership costs
- Depreciation: Vehicles lose value over time, which is factored into the cost per kilometer
- Finance Costs: If your vehicle is financed, interest payments are included in the calculation
2018 AA Rates Breakdown by Vehicle Type
The following table shows the average rates per kilometer for different vehicle types in 2018:
| Vehicle Type | Cost per km (R) | Fuel % | Maintenance % | Insurance % | Depreciation % |
|---|---|---|---|---|---|
| Small Car (≤1.4L) | 0.85 | 32% | 18% | 15% | 35% |
| Medium Car (1.4L-2.0L) | 1.12 | 30% | 17% | 14% | 39% |
| Large Car (>2.0L) | 1.45 | 28% | 16% | 13% | 43% |
| Luxury/Executive | 1.98 | 25% | 15% | 12% | 48% |
| 4×4/SUV | 1.72 | 27% | 16% | 13% | 44% |
How Fuel Prices Affect Your Cost Per Kilometer
Fuel prices in South Africa are subject to monthly adjustments based on international oil prices and the rand/dollar exchange rate. In 2018, petrol prices ranged from R14.00 to R16.50 per liter, while diesel prices were slightly lower at R13.50 to R15.80 per liter.
The following factors influence fuel prices:
- International Crude Oil Prices: The basic fuel price is based on the import parity price of petroleum products
- Rand/Dollar Exchange Rate: Since oil is traded in dollars, a weaker rand increases fuel prices
- Fuel Levies: The general fuel levy (R3.37 in 2018) and Road Accident Fund levy (R1.93 in 2018) are included in the pump price
- Transport Costs: The cost of transporting fuel from coastal storage facilities to inland areas
- Retail Margins: The profit margin for fuel station owners
For example, if you drive a medium car with fuel efficiency of 7.5L/100km and fuel costs R15.50 per liter, your fuel cost per kilometer would be:
(7.5L × R15.50) ÷ 100km = R1.16 per km
Maintenance Costs and Their Impact
Maintenance costs vary significantly between vehicle types and brands. The AA estimates that maintenance costs account for approximately 15-18% of the total cost per kilometer. These costs include:
- Regular services (every 15,000km or 12 months)
- Tyre replacements (every 50,000-80,000km)
- Brake pad and disc replacements
- Battery replacements (every 3-5 years)
- Unexpected repairs
Vehicles with maintenance plans typically have lower maintenance costs in the short term, but these costs are often built into the vehicle’s purchase price or monthly installments.
Insurance Considerations
Vehicle insurance is a significant component of the cost per kilometer, typically accounting for 12-15% of the total. Insurance premiums are influenced by:
- Vehicle value and type
- Driver’s age and claims history
- Area where the vehicle is kept
- Annual mileage
- Security features
- Excess amount
In 2018, the average comprehensive insurance premium for a medium-sized car was approximately R12,000 per year. For a vehicle driving 20,000km annually, this translates to R0.60 per kilometer.
Depreciation: The Hidden Cost
Depreciation is often the largest single component of vehicle ownership costs, accounting for 35-48% of the total cost per kilometer. New vehicles typically depreciate by 15-20% in the first year and 10-15% per year thereafter.
Factors affecting depreciation include:
- Vehicle make and model (some brands hold value better than others)
- Mileage (higher mileage generally means greater depreciation)
- Condition and service history
- Market demand for the particular vehicle type
- Economic conditions
For example, a new medium car purchased for R300,000 that depreciates to R180,000 after 3 years (60,000km) would have a depreciation cost of R2.00 per kilometer.
How to Reduce Your Cost Per Kilometer
While some costs are fixed, there are several strategies to reduce your overall cost per kilometer:
- Improve Fuel Efficiency:
- Maintain proper tyre pressure
- Remove excess weight from the vehicle
- Drive smoothly and avoid aggressive acceleration/braking
- Use cruise control on highways
- Service your vehicle regularly
- Reduce Maintenance Costs:
- Follow the manufacturer’s service schedule
- Use quality parts and fluids
- Address small issues before they become major problems
- Consider extended warranties or maintenance plans
- Lower Insurance Premiums:
- Increase your excess
- Install security devices
- Park in secure locations
- Consider usage-based insurance
- Shop around for competitive quotes
- Minimize Depreciation:
- Choose models with strong resale values
- Keep mileage reasonable
- Maintain complete service records
- Keep the vehicle in good condition
- Consider leasing instead of buying
Comparing 2018 Rates to Previous Years
The following table compares the AA rates per kilometer from 2016 to 2018 for medium-sized cars:
| Year | Cost per km (R) | Fuel Price (R/L) | Fuel % | Maintenance % | Insurance % | Depreciation % |
|---|---|---|---|---|---|---|
| 2016 | 1.05 | 12.50 | 31% | 18% | 15% | 36% |
| 2017 | 1.09 | 13.80 | 30% | 17% | 14% | 39% |
| 2018 | 1.12 | 15.50 | 30% | 17% | 14% | 39% |
The data shows a steady increase in the cost per kilometer, primarily driven by rising fuel prices and vehicle costs. The proportion allocated to fuel remained relatively constant, while depreciation became a slightly larger component of the total cost.
Tax Implications of Vehicle Usage
For business owners and employees who use their vehicles for work purposes, the AA rates per kilometer are important for tax calculations. The South African Revenue Service (SARS) allows for tax deductions based on business travel kilometers.
In 2018, SARS set the following rates for business travel:
- R3.61 per kilometer for the first 12,000km per year
- R1.05 per kilometer for distances exceeding 12,000km per year
These rates are generally lower than the actual AA rates, which means that many motorists may not be fully compensated for their actual vehicle costs when claiming business travel expenses.
Electric and Hybrid Vehicles
While not prominently featured in the 2018 AA rates (due to their limited market share at the time), electric and hybrid vehicles offer significantly different cost structures:
- Lower Fuel Costs: Electric vehicles have no fuel costs, while hybrids consume significantly less fuel
- Higher Initial Costs: Electric and hybrid vehicles typically have higher purchase prices
- Lower Maintenance Costs: Fewer moving parts mean reduced maintenance requirements
- Different Depreciation Patterns: Early electric vehicles depreciated rapidly, but this trend is changing as the technology matures
In 2018, the cost per kilometer for electric vehicles in South Africa was estimated at R0.50-R0.70, significantly lower than conventional vehicles, primarily due to the lower “fuel” costs (electricity vs. petrol/diesel).
Frequently Asked Questions About AA Rates Per KM
How often are the AA rates updated?
The AA typically updates its rates per kilometer annually, usually in the first quarter of each year. These updates reflect changes in fuel prices, vehicle costs, maintenance expenses, and other factors affecting the cost of vehicle ownership.
Can I use these rates for tax purposes?
While the AA rates provide a comprehensive view of vehicle ownership costs, SARS has its own prescribed rates for tax deductions. You should use the SARS rates for tax calculations, but the AA rates can help you understand your actual costs and make informed financial decisions.
Why is there such a big difference between vehicle types?
The differences in cost per kilometer between vehicle types are primarily due to:
- Purchase price (luxury vehicles cost more to buy and thus depreciate more)
- Fuel consumption (larger engines typically consume more fuel)
- Maintenance costs (more complex vehicles often cost more to maintain)
- Insurance premiums (more expensive vehicles cost more to insure)
How accurate are these calculations?
The AA rates provide a good general estimate of vehicle ownership costs, but your actual costs may vary based on:
- Your specific driving habits
- The actual fuel efficiency of your vehicle
- Where and how you maintain your vehicle
- Your insurance premiums
- The actual depreciation of your particular vehicle
Should I consider these rates when buying a car?
Absolutely. Understanding the total cost of ownership (as reflected in the AA rates per kilometer) is crucial when making a vehicle purchase decision. A vehicle with a lower purchase price might actually cost more per kilometer to run than a slightly more expensive but more efficient model.
