Most calculators stop at a pot size. This one keeps going.
A single “you need £1.2M” hides everything that matters — when you can actually access the money, and what the taxman takes on the way out. Fireworks models the mechanics.

Income-tax bands, the personal-allowance taper, CGT above the £3,000 exemption and the 25% tax-free pension — solved year by year, not hand-waved.
