Help & Frequently Asked Questions

Are the calculators free?

Yes. The tools can be used without registration or a subscription.

Do the currency selectors convert money?

No. They change output labels only. Use one currency consistently for all monetary inputs in a calculation.

Are the example prices current?

No. Default values and guide examples are illustrative. Enter your own current quotes, prices and rates.

Are my calculator inputs saved?

Not automatically. Calculations run in your browser. Print or download the output you need before leaving, refreshing or closing the page.

Can I export the results?

Yes. Each tool provides Print result and Download CSV. The loan CSV includes monthly amortisation; the on-page schedule groups it by year.

Why is ownership cost not a full purchase comparison?

The ownership calculator covers annual running costs only. Purchase price, depreciation, loan principal and financing interest are excluded so the scope is clear.

Can I rely on a depreciation result when selling?

No. It is a scenario based on your chosen rate, not a market valuation. Check comparable offers, condition and relevant documentation separately.

Is EV charging time exact?

No. The model assumes a constant effective input power. Real charging may taper or vary with temperature, vehicle limits and household load.

What should I do if I find an error?
