This is an estimate to give you a ballpark figure, not a guarantee. It assumes 5% gross investment growth less 1.5% charges (3.5% net), 2% inflation, contributions rising 3% a year, and income drawn at a steady rate. All figures are shown in today’s money. The charges and drawdown assumptions are Mr MoneyJar’s own. Figures do not account for income tax. This is not financial advice so please seek regulated advice before making any decisions about your pension.
