Path to financial freedom

Your net worth over time. The blue pension band stays locked until 57. The coral accessible band is what you can touch any time (ISA, LISA, Cash, GIA). The black line is the total. Net worth dips after retirement because you're drawing down to live.

Small tweaks, big shifts

Soon you'll be able to test single-lever changes — *what if I saved £100 more, cut £100 in expenses, or overpaid the mortgage?* — and watch your Freedom Day move in real time.

  • Save £100 more / month
    Add £100/mo to your ISA contribution
    shaves months off your Freedom Day
  • Cut £100 / month from expenses
    Lower spending raises your savings rate AND lowers your FIRE number
    double-impact lever — often the biggest
  • Overpay mortgage £200 / month
    Trade liquidity for interest saved
    clears the mortgage years earlier
