Choose Algarve or Madeira before trusting the £500k answer
The same £500,000 plan can feel different in mainland Portugal and on Madeira because housing markets, flights, healthcare access and island logistics are not identical. Use this page to test the household cashflow, then compare the actual Portugal places before treating the result as a destination decision.

Why £500k can produce another answer
Retirement age, asset access, State Pension, DB income and spending matter. Portugal may not recognise ISA tax-free treatment, and Portuguese personal tax is not calculated.
Tax framework and limitations
Portugal is framework-only, not fully modelled. The current UK–Portugal treaty and resident-tax framework are recorded for State Pension and ordinary pensions. Flexible DC withdrawals, lump sums, government-service pensions, investments, UK property and treaty relief require individual analysis. Portugal may not preserve ISA tax-free treatment.
Healthcare and residence
Residents may access the SNS, and eligible UK State Pension recipients may register an S1. Eligibility is not guaranteed; pre-registration private cover and user costs remain editable allowances. Visa and residence-card qualification are not assessed. This is not tax, legal, immigration or healthcare advice.
Portugal is not one cost profile
Algarve and Madeira have different housing, travel and island-access assumptions. RetirementInSight models supported financial inputs; WhereCanIRetire helps decide which place may suit you.
