I've just re-done my monthly budget, and have freed up enough money to put £200 per month extra into a pension. I'm currently in the TPS (teacher's pension) on the career average arrangement, which apparently means I accrue that pension at the rate of 1/57. I can also "buy" a faster accrual rate of 1/45. As well as the TPS, I have a private defined contribution pension with Aviva from a previous job.
Is it better to spend the £200 per month buying a faster accrual rate, or to put it into the Aviva defined contribution pension?
I know defined benefit pensions are generally supposed to be better, but I don't know whether it's good to also have a defined contribution pension. I'm thinking perhaps I could pay the £200 into the Aviva defined contribution pension so that I can retire early - and frugally - on it, without taking the hit for early retirement on the TPS pension? Or as a back-up in case the TPS pension goes bust?
My salary is £32k and I'm 39.
