Five concrete examples of the Fuel Cost Calculator in real use. Each one shows the situation, what you put in and what comes out, so you can copy the structure, swap in your details and adapt it this week.
Example 1: Estimating fuel cost for a road trip
The task: Estimating fuel cost for a road trip. You start from trip distance, vehicle fuel economy in mpg or l per 100 km, and fuel price per unit.. The tool returns fuel needed for the trip and the estimated total fuel cost., giving you a budget figure for the drive before you set out. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 2: Comparing two routes on running cost
The task: Comparing two routes on running cost. You start from trip distance, vehicle fuel economy in mpg or l per 100 km, and fuel price per unit.. The tool returns fuel needed for the trip and the estimated total fuel cost., giving you a budget figure for the drive before you set out. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 3: Checking a commute cost per month
The task: Checking a commute cost per month. You start from trip distance, vehicle fuel economy in mpg or l per 100 km, and fuel price per unit.. The tool returns fuel needed for the trip and the estimated total fuel cost., giving you a budget figure for the drive before you set out. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 4: Converting between mpg and l per 100 km
The task: Converting between mpg and l per 100 km. You start from trip distance, vehicle fuel economy in mpg or l per 100 km, and fuel price per unit.. The tool returns fuel needed for the trip and the estimated total fuel cost., giving you a budget figure for the drive before you set out. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 5: Budgeting fuel before a holiday drive
The task: Budgeting fuel before a holiday drive. You start from trip distance, vehicle fuel economy in mpg or l per 100 km, and fuel price per unit.. The tool returns fuel needed for the trip and the estimated total fuel cost., giving you a budget figure for the drive before you set out. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
A Full Worked Example
Input: 320 miles, 32 mpg, fuel at $3.45 per gallon
10 gallons needed, estimated cost $34.50.
The pattern behind every example above: context and constraints go in, structure comes out, and your edit makes it true.
How to Build Your Own Examples
- Take a task already on your calendar for this week.
- Write the brief in two sentences: the job and the audience.
- Generate, compare against the version you would have written manually.
- Save the prompt alongside the result so the second run takes seconds.
Getting More From Each Example
Most people stop at the first result. Generate a second version with one changed variable - length, tone or angle - and compare. The better version usually appears on the second run, not the first.
Frequently Asked Questions
How is fuel cost calculated?
Distance divided by fuel economy gives fuel needed; multiply that volume by your price per unit for the trip cost.
Which fuel economy figure should I use?
Your own observed mpg from fill-ups beats brochure numbers - real driving usually sits a little lower.
Does it support litres per 100 kilometres?
Yes - switch the economy unit and keep distance and price in the matching metric or imperial system.
Is my trip data stored?
No - everything runs in your browser.
