This tool gives an indicative timeline only, it is not regulated financial advice. Interest is compounded monthly at the rate you entered, and the LISA bonus is modelled as paid annually (with a pro-rata top-up in the final partial year). Interest rates and LISA rules can change. Always check current limits and seek independent advice before major financial decisions.
