If you put £100,000 in a fixed rate account at 4% interest you would ear £4000 before tax. But don't forget that the most you can put in any one savings account under the Government's compensation scheme is £50,000 (or £100,000 for a joint account), so if you're lucky enough to have that kind of money, spread it around to be on the safe side.
thanks for the link,im thinking of selling my house, profit will be around that,didnt know wether to save it and rent for a year and find a house,was just wondering if financially it would be a good idea.thanks
If you want instant access to your money most high street banks pay less than 1%. If you want more than 3% it may pay to take out a bond where the money cannot be touched until the bond expires. Depending on how long you want the bond to run for, it can be 6 months, 1 year, 18 months, 2 years, 3 years and 5 years there is an increasing interest payable. Some banks will alow monthly interest though.
Currently, you with a sum of this amount you could potentially get a better rate using a money market account. Many UK banks offer these, and you'd be able to enquire in a branch. It could be an option until you decide how to invest, and give a better rate than standard savings account which currently only pay pitiful rates. You'd also only be able to get up to £20k in an ISA anyway.
