Retirement Monte Carlo, tax-aware withdrawals, 2026 tax calculators, RMD, IRMAA, every-state tax.
이 세 가지는 절대 하나의 점수로 합치지 않아요. 의견, 측정, 인기는 서로 다른 것이니까요.

run_retirement_projectionRuns a Monte Carlo retirement projection on the QuantCalc engine and returns the success rate, the ending-portfolio distribution, and the assumptions that produced them.

Federal and

Every input is optional: omitted plan inputs use an illustrative plan (age 65, $
list_return_assumption_sourcesReturns the published capital market assumption sets the engine carries and which components each publisher provides (returns, volatilities, correlations).

Gives Claude the retirement engine and the federal and state tax engines behind quantcalc.app, so a projection or a 2026 tax figure is computed rather than estimated.
A language model cannot run thousands of correlated return paths against a spending plan and get the odds right. It can ask something that can.

Twenty-two tools. "Free" means the tool computes without a licence key; "Licence" means it needs a connected QuantCalc PRO licence or Tax Season Pass (PRO only where stated), and without one it computes nothing and names the free web page that does.

explain_methodology | Free | What the engine models and what it deliberately leaves out |

All twenty-two are read-only: they compute and return, and change nothing. Inputs are not kept after the run, except that a failed request is kept for two days to diagnose it.
A success rate is meaningless without its assumptions, and a summary will drop a caveat it was not handed explicitly. So each result states:
Optional. Without one, projections run at 2,000 paths (the 95% interval around a success rate is about ±1.5 points) and the tax-aware tool returns the first retirement year of its year-by-year schedule. A QuantCalc PRO key raises that to 10,000 paths (about ±0.7) and returns the full schedule. The tax engine inside the projections — withdrawal order, Roth conversions, state tax — needs no key.
The 2026 tax tools run on QuantCalc's licensed federal and state tax APIs and need a PRO or Tax Season Pass key: estimate_2026_tax_return, state_tax_in_every_state, calculate_2026_income_tax, pretax_contribution_savings, business_deduction_tax_savings, roth_conversion_tax_cost, qcd_tax_savings, social_security_taxable_amount, capital_gains_tax, estimated_tax_payments_2026, the tax part of calculate_rmd and the credit in aca_premium_tax_credit. Without a key they compute nothing and name the free web page for the same question (for example https://quantcalc.app/2026-tax-return-calculator/). irmaa_check, the RMD itself, the 2027 ACA benchmark, cliff and headroom, the retirement-plan contribution limit by age, the IRA deduction and Roth limit worksheets, and the standard deduction amount are free; the tax each of those saves needs a key. optimize_social_security_claiming needs a PRO key. The same key also unlocks the portfolio optimizer, glide paths, custom capital market assumptions and multi-period planning in the QuantCalc app. Those features are not tools in this plugin.
Set it in the plugin's configuration. It is sent as a connection header and never passes through the conversation.
