Fuel Costs Under Control: Track Consumption

To get your fuel costs under control, record every fill-up in Berta with its liters, price and odometer reading – by photographing the receipt, by voice, or by keyboard. From at least two fill-ups with odometer readings, Berta calculates your average consumption in l/100 km and shows you in the costs tab what your car really costs.

The key facts

• Record every fill-up: liters, price and odometer.
• Average consumption: l/100 km from two fill-ups with odometer readings.
• Costs tab: monthly cost bars, cost per km, monthly fuel cost, total costs.
• Enter by photo, voice or keyboard – Berta reads the values, you confirm.
• Currencies: EUR (default), CHF, USD; units metric or imperial.

Why tracking is worth it

Knowing your consumption lets you spot outliers immediately: a sudden rise that hints at a technical problem, or unusually expensive months. Instead of guessing, with Berta you have concrete numbers – and a basis to adjust your driving or fueling habits.

How do I record a fill-up?

You have three routes. Fastest is to photograph the fuel receipt; with AI consent Berta reads out the values. Alternatively you type in liters, price and odometer. And on the go you can speak the liters and the price or total, in the app just as on the web – Berta needs at least the liters plus either the price per liter or the total.

The key is to include the odometer reading with every fill-up. It's the basis for the consumption calculation.

How does Berta calculate consumption?

Average consumption in l/100 km appears once at least two fill-ups with odometer readings exist. Berta works out the distance between the readings and relates it to the fuel added. The more regularly you record the odometer, the more accurate the figure. If a number is still missing, you've probably only recorded one fill-up with an odometer reading.

What does the costs tab show me?

The costs tab brings all breakdowns together: monthly cost bars, average consumption, cost per km, monthly fuel cost and your vehicle's total costs. So you see at a glance how your costs develop over the months and where savings potential lies.

You capture regular expenses like insurance or road tax as a cost event with a category, billing period and optional recurrence – so they flow into total costs too.

Which currencies and units suit me?

Berta works in EUR (default), CHF or USD and shows consumption in metric or imperial. Set both once to match your country and all breakdowns are correct. If you drive abroad or fill up near a border, the right currency setting helps you compare your costs cleanly.

How do I assign costs cleanly?

Berta distinguishes several entry types so your breakdowns stay accurate. Fuel entries feed into consumption and fuel costs, plain odometer readings improve the consumption calculation, service entries record workshop visits, and notes let you add free remarks. For recurring fixed costs you use cost events with a category and billing period.

If you capture by photo with AI consent, Berta highlights fields with a confidence below 80% for review – a helpful safeguard with odd fuel totals or blurry receipts. You always confirm before an entry is saved, so no wrong figures distort your cost analysis.

What happens if I fill up offline?

Many stations have poor signal – no problem. If you record a fill-up offline, it waits in the queue and is re-sent automatically once you're back online. No duplicates are created. So you collect data without gaps and build a clear picture of your fuel costs, fill-up by fill-up.
