FolioForecast

FolioForecast is a calculator for portfolio and retirement planning. It is built for people who want to analyze a portfolio, stress-test a retirement path, or ask an AI to call FolioForecast for calculator output it can explain. The site describes its outputs as model results, not investment advice.

Its portfolio tools include loading a sample or importing holdings, then comparing historical return, volatility, max drawdown, and candidate allocation outputs. The page also highlights efficient frontier analysis and presents four core metrics in plain language: expected return, volatility, max drawdown, and Sharpe ratio. In the portfolio section, sample outputs show historical-return projections, a likely range, and starting points such as 60/40 Classic, All S&P, Tech Heavy, All-Weather, Growth, and Conservative. The retirement planner is guided and lets users adjust retirement age, savings, return, and withdrawal assumptions, with Monte Carlo-style uncertainty bands and scenario output that updates in real time.

A budget support module sits alongside those planning tools. It tracks income and spending, estimates monthly surplus, and carries that amount into retirement assumptions. The page also says budget stays in the background as the support module that finds investable surplus for retirement. For AI use, FolioForecast connects with Claude Desktop or ChatGPT Actions through limited-scope, revocable access, and the page mentions MCP as part of that setup. It also says no signup is needed to try sample math.

The service emphasizes transparent methodology. It says every calculation has a show-your-work link with formulas, inputs, and assumptions, and it states that it does not manage money, earn commissions, or take referrals from brokers. The page also says user data is not sold and is not used to train models. No pricing details are stated on the page.
