If you enter an income with a start date in the future, and the increase has been set to "None", there will be no increase to the income in deferment or in payment. If you enter an income and the increase has been set to "CPI", it will automatically increase the income in deferment and in payment.
For example, £30,000 gross income which has the increase option set to "CPI", will show as £30,000 gross income at the future date, because our charts are always shown in today's values.
For incomes where the increase option is set to "None", the gross income shown will be the value for the £30,000 reduced by inflation. The only exception to this rule is that Defined Benefit schemes always increase in deferment, even if None has been selected for an increase since this is standard for most scheme benefits.
