How much extra are Australians paying for fuel in 2026?
Many Australians may be paying noticeably more for fuel right now than they were only weeks earlier. The practical difference depends on how many litres your household uses, not just the cents-per-litre headline.
The short answer is that many households may be paying significantly more right now than they were only weeks earlier. The ACCC said the five-largest-city average retail petrol price reached 219.7 cpl on 11 March 2026, up 48.8 cplsince 20 February. If your household uses 50 litres a week, that kind of move matters quickly.

| Weekly usage | +20.0 cpl | +40.0 cpl | +50.0 cpl |
|---|---|---|---|
30 litres per week Weekly / monthly / annual extra cost | $6.00 / $26.00 / $312.00 | $12.00 / $52.00 / $624.00 | $15.00 / $65.00 / $780.00 |
50 litres per week Weekly / monthly / annual extra cost | $10.00 / $43.33 / $520.00 | $20.00 / $86.67 / $1,040.00 | $25.00 / $108.33 / $1,300.00 |
70 litres per week Weekly / monthly / annual extra cost | $14.00 / $60.67 / $728.00 | $28.00 / $121.33 / $1,456.00 | $35.00 / $151.67 / $1,820.00 |

What official data shows
The ACCC reported the five-largest-city annual average retail petrol price at 179.3 cpl in calendar-year 2025, versus 188.0 cpl in 2024. That tells you 2025 was not a simple story of prices always getting worse.
But current household experience can still be materially worse right now. A recent spike matters more to cash flow than a historical annual average, because households are paying the price they see today at the bowser, not the average of last year.
Worked example: 50 litres a week at March 2026 spike levels
This approximates a 50-litre weekly household using the ACCC five-city average reported for 11 March 2026.

- Weekly litres used, not just kilometres driven
- City differences and local price-cycle timing
- Vehicle type and fuel efficiency
- One-car versus multi-car households
- Regional versus inner-city transport alternatives
What that means over a year
Weekly differences can look small in isolation, but they grow when prices stay elevated. An extra $10 a week is roughly $43 a month or $520 a year. An extra $20 a week is roughly $87 a month or $1,040 a year.
That is why it helps to compare fuel rises against your wider cost-of-living picture, not just the last fill-up. If a higher petrol bill is squeezing other goals, compare it with the rest of your budget in the cost-of-living guide.
How to estimate your own “extra”
Start with your normal older fill-up price and compare it with the price you are paying now. Then multiply the difference by your usual litres per week. This gives you the extra weekly cost, which you can convert into monthly and annual terms.
The easiest way to do that is to run one scenario in the fuel cost calculator using your earlier price, then re-run it with your current price and compare the result. If you want to see how that fits into the wider household picture, follow it up with our weekly fuel benchmark guide.

How this page works
This page converts recent fuel-price increases into practical weekly, monthly, and annual household cost scenarios while distinguishing annual averages from current price spikes.
Methodology
- Compare recent cents-per-litre increases against a weekly litres-used example.
- Translate those weekly differences into monthly and annual household impact.
- Explain the difference between annual average prices and the price households may be paying right now.
- Prompt readers to compare their own earlier and current fill-up prices in the calculator.
Assumptions
- Examples use simple litres-per-week scenarios to keep the maths easy to follow.
- The page uses date-labelled market context rather than treating volatile prices as timeless facts.
Limitations
- Short-term prices can move sharply within weeks.
- A five-city average does not reflect every suburb, town, or regional market.
