How this site is funded

Our calculators are free to use. We may earn a commission when you make a qualifying purchase through a clearly marked affiliate link. The retailer’s programme terms determine eligibility and commission.

Independent calculations

Affiliate commission does not change the arithmetic. We do not claim to have tested appliances and do not fabricate reviews, star ratings or customer experiences. Product data describes the named source and test basis.

Programme approvals

Commercial offers appear only after the operator has permission to use the data and promote that advertiser. An empty catalogue means no current approved offers are available. The site does not currently claim membership of any affiliate programme.

Advertising and sponsored content

Display advertising is disabled pending approval and consent integration. Any future sponsorship must be labelled. We do not accept payments to fabricate an outcome in a calculator.
