An annual (standard class) season ticket from Cambridge to London
Terminals is £3640 and to London Zones R1256 is £4600, a difference of
£960.

If you simply commute on working days only to a Zone 1 underground
station and use a pre-pay OysterCard, the annual cost of your tube
travel would be about £1.50 x 2 x 5 x 48 which is £720. So even if you
make occasional additional journeys at weekends, beyond Zone 1 or on
the bus it might be cheaper to get a London Terminals ticket and use a
pre-pay OysterCard.

Note, incidentally, that if you're commuting from Cambridge to the
City of London (and don't fancy the Liverpool Street line) then you
can use a Cambridge - London Terminals ticket on the underground
between King's Cross and Moorgate.
