WealthStoryLine runs a 3,000-path Monte Carlo simulation of a household's finances: one household income, living expenses, today's savings and investment returns, under random inflation, salary growth and market returns. Ask questions such as "Can I retire at 60?", "Will my savings last?" or "Can I reach $500,000 by 45?" and get the probability of reaching your goal, the bankruptcy rate and net-asset ranges for good, middle and bad outcomes in today's money, together with the assumptions that were used.
Who it is for: individuals, couples and financial educators who want to check a plan and its risks in plain language. It supports about 190 countries; Taiwan, Japan, the US, China and Canada use curated assumptions, other countries use 2005-2024 averages of official statistics (World Bank, OECD, BIS).
No sign-in is required. The plugin receives only the numbers needed for a simulation, not your conversation; anonymous inputs and results are deleted after 30 days.
Limitations: results are projections for planning discussions, not financial advice or a guarantee. Home purchases, mortgages, several incomes and fund portfolios are not modelled in this plugin (they are available on the WealthStoryLine website). Taxes and insurance are not modelled. It cannot trade, move money or connect to bank or brokerage accounts.
