Runs educational money calculations with no sign-in: compound interest, Rule of 72, Coast FIRE and FIRE numbers, 401(k) employer match using 2026 IRS limits, debt payoff with avalanche or snowball comparison, and savings goals. Also searches and reads Compound Mint guides. Results are not financial advice.

Example request: "If I put $500 a month into an index fund at 7% for 25 years, how much would I have, and what 401(k) match am I leaving on the table at a $90,000 salary?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Compound Mint Money Calculator to help me. It is a free service with an MCP server at https://compoundmint.com/wp-json/mint/v1/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
