How it works and an example to tryShow less
How to use the result
Contributions compound at growth after fees to retirement age, then are deflated by inflation. Income applies the drawdown rate. The extra contribution to hit the target is solved numerically.
Example to try
£45,000 at 35 with £600 a month at 5% growth reaches about £470,000 by 67, £215,000 in today's money: £8,600 a year at 4%. Reaching £30,000 needs roughly £1,500 more a month.
