Ten metrics × ten sub-metrics
Every metric and sub-metric is scored 1–10, where 10 is best for the investor. Each broker's figure carries its own source and verification date — click any ↗ button to open the exact page that figure was read from.
Scores are calculated by this site, not issued by the brokers. Each sub-metric is scored
1–10 by ranking the researched brokers' published figures on that single line, cheapest or
most favourable to the investor scoring highest; identical figures receive identical scores. A
metric's headline score is the mean of its ten sub-scores, shown to one decimal.
Every figure is sourced and dated per broker, because brokers publish pricing in different places
and update on different schedules. Brokers marked not researched show no score at all
rather than a guess. Scores compare only what is published — they do not weight how much
each line matters to you, and a broker cheap on commission may be expensive on margin.
