What this server can do
6 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
calculate_coast_fire(currency, current_age, inflation_rate, current_savings, monthly_savings, expected_return_rate, portfolio_volatility, safe_withdrawal_rate, target_retirement_age, annual_expenses_in_retirement)- Compute the Coast FIRE milestone — the capital required today such that, with no further contributions, a portfolio compounds to the user's retirement target by their target age. Required: current_age, target_retirement_age, current_savings, annual_expenses_in_retirement.
calculate_fire_target(years, currency, annual_expense, inflation_rate, apply_inflation, current_savings, portfolio_volatility, portfolio_return_rate)- Estimate the savings target needed for Financial Independence / Early Retirement. Runs Monte Carlo simulation and returns the probability the portfolio survives the planning horizon. Required: annual_expense, years.
compute_swiss_property_tax(canton, sale_price, years_held, purchase_price, ersatzbeschaffung, ersatzbeschaffung_amount)- Estimate the Swiss cantonal real-estate capital gains tax (Grundstückgewinnsteuer) for a property sale. Covers all 26 cantons with holding-period adjustments and Ersatzbeschaffung (replacement-residence) deferral. Educational estimate; commune surcharges and value-enhancing-improvement deductions are not modeled. Required: canton, sale_price, purchase_price, years_held.
get_portfolio_returns(currency)- Return RetireCrunch's historical portfolio return profiles for a currency. Each profile is a (return %, volatility %) pair derived from real index data — useful for grounding the assumptions in calculate_fire_target / project_wealth_plan in something defensible rather than guessing. Required: currency.
project_wealth_plan(region, currency, start_year, yearly_detail, household_type, inflation_rate, retirement_year, current_mortgage, current_property, current_liquidity, income_yield_rate, estimated_tax_rate, plan_horizon_years, property_sale_year, current_living_costs, portfolio_volatility, current_earned_income, portfolio_return_rate, portfolio_switch_year, property_sale_enabled, current_other_expenses, current_housing_expenses, portfolio_switch_enabled, post_retirement_tax_rate, property_sale_destination, current_investment_portfolio, partner_survivor_expense_factor, partner_early_death_years_before_end)- Run RetireCrunch's full year-by-year Wealth Plan projection for a household. Models earned income, pensions, expenses, portfolio growth, optional growth→income phase switch, mortgage amortization, optional property sale, and region-aware tax (US uses 2026 federal+state brackets; other regions use a flat rate). Returns a compact summary with 5-year milestones by default, or the full annual array when yearly_detail=true. Required: start_year, retirement_year.
rebalance_portfolio(fx_rates, holdings, base_currency, class_targets, available_cash)- Rebalance a multi-currency portfolio: given holdings, per-holding (or per-asset-class) target weights, cash and FX rates, return the exact BUY/SELL trades to reach the targets, the per-currency cash movements (flagging foreign-cash overdrafts), and a summary. Planning math only — no transaction costs or taxes. Required: holdings.

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
