The amount of Council Tax charged for band I properties is currently 3 and a half times as much as band A, but homes in the top band are worth at least 9 times as much as those in the bottom band.
Ar hyn o bryd mae'r Dreth Gyngor a godir ar eiddo ym mand I deirgwaith a hanner cymaint â band A, ond gallai cartrefi yn y band uchaf fod yn werth naw gwaith cymaint â'r rhai yn y band isaf.
