A little late to add this in now but having read the other comments I wanted to clarify this for you -
The figures quoted for State Pension Before are only correct if the husband has got a 100% basic pension, meaning he will have to have paid NI (national insurance) for 49 years in his working life, or have been credited with NI while he has been receiving CA, which will be the case.
The correct state pension figure is 84.25 from 10.04.06. If Mr has only paid enough NI to receive 90% of the basic pension then assuming Mrs isn't receiving more than 90% in her own right then hers would only be increased to 90% upon Mr reaching 65.
