calculate_fire_target | Estimate the savings target needed for Financial Independence / Early Retirement. Runs Monte Carlo simulation and returns the probability the portfolio survives the planning horizon. params: annual_expense*, years*, current_savings, currency, portfolio_return_rate, portfolio_volatility, apply_inflation, inflation_rate |
calculate_coast_fire | 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. params: current_age*, target_retirement_age*, current_savings*, annual_expenses_in_retirement*, currency, expected_return_rate, inflation_rate, safe_withdrawal_rate, monthly_savings, portfolio_volatility |
compute_swiss_property_tax | 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. params: canton*, sale_price*, purchase_price*, years_held*, ersatzbeschaffung, ersatzbeschaffung_amount |
project_wealth_plan | 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 wh params: region, currency, start_year*, retirement_year*, plan_horizon_years, current_earned_income, current_living_costs, current_housing_expenses, current_other_expenses, estimated_tax_rate, post_retirement_tax_rate, current_liquidity, current_investment_portfolio, current_property, current_mortgage, inflation_rate, portfolio_return_rate, portfolio_volatility, portfolio_switch_enabled, portfolio_switch_year, income_yield_rate, household_type, partner_early_death_years_before_end, partner_survivor_expense_factor, property_sale_enabled, property_sale_year, property_sale_destination, yearly_detail |
get_portfolio_returns | 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. params: currency* |
rebalance_portfolio | 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. params: base_currency, fx_rates, available_cash, holdings*, class_targets |
load_portfolio | Open the user's Interactive Brokers portfolio in the RetireCrunch Portfolio Rebalancer. First call the IBKR connector's get_account_positions, get_account_balances and get_account_summary, then pass their results here UNCHANGED (do not re-type or round numbers). Returns a private link that works once, for 15 minutes — give it to the user exactly as written. No login is needed because the link itse params: positions*, balances, summary, language |
get_rebalance_plan | Fetch the rebalancing trades the user decided on in the RetireCrunch Rebalancer, from the plan code they copied ("Send plan to my AI"). Codes work once, for 15 minutes. Returns the trades with IBKR contract ids where known. To act on them, create one IBKR order instruction per trade (create_order_instruction); the user reviews and submits each one inside IBKR. RetireCrunch never places orders. params: code* |
