Analyze a portfolio, stress-test your retirement path, or let your AI call FolioForecast for calculator output it can explain.
FolioForecast is a calculator. Scenario outputs are model results, not investment advice.
Pick the lane that matches the question in front of you. Budget stays in the background as the support module that finds investable surplus for retirement.
Load a sample or import holdings, then compare historical return, volatility, max drawdown, and candidate allocation outputs.
Use the guided planner to test retirement age, savings, withdrawal assumptions, and Monte Carlo-style uncertainty bands.
Connect Claude Desktop or ChatGPT Actions to FolioForecast tools with limited-scope, revocable access.
Pick a starting point, adjust the mix, and watch how $10,000 could grow based on historical returns. Outputs are scenario math, not a buy or sell instruction.
Every chart on Folio comes back to these four. Once you know what they mean, you can judge any portfolio in 30 seconds.
How much it grows in a typical year. The average annual gain, based on the last decade of real market data.
How bumpy the ride is. Higher volatility means bigger up-and-down swings along the way.
The worst pain it's ever caused. The biggest peak-to-trough loss you would have lived through.
Your risk-adjusted score. Higher is better — it's how you compare two portfolios fairly.
Retirement is the reason the portfolio math matters. Move age, savings, return, and withdrawal assumptions to see scenario output change in real time.
Institutional-grade math, translated for humans — and a handful of honest commitments about how we operate. Whether you're starting out or running a $5M portfolio, you get the same numbers and the same promises.
No black boxes. Every number shows its work — what went in, what came out, and why it matters. If you can't verify it, we shouldn't be asking you to trust it.
"Sharpe ratio" becomes "return per unit of risk." "Efficient frontier" becomes "the efficient trade-off for a given risk level." Math stays the same. Words get better.
We don't manage your money, earn commissions, or take referrals from brokers. The math is the product. You make the decisions.
We never sell it. We never use it to train models. With MCP, it can stay on your machine entirely when you want it to.
No hidden affiliate links. No fund lists we get paid to promote. The page you see is the page everyone sees.
Every calculation has a "show your work" link with the formula, inputs, and assumptions. Disagree with our defaults? Change them.
Budget is the support module: track income and spending, estimate monthly surplus, and carry that number into retirement assumptions.
Connect ChatGPT Actions or Claude/MCP so an AI assistant can request calculator output from FolioForecast and explain the model output in plain English.
Use a revocable agent key or OAuth connector. Keep full-access keys out of chats.
Use Claude Desktop/local MCP, Claude web connectors, or ChatGPT Actions where supported.
