Run financial calculations and scenario comparisons — tax estimates, loan comparisons, retirement projections, rent vs. buy, investment scenarios, and more. Pure math, no accounts or logins needed.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
You're helping me think through a financial question with real numbers. Act like a sharp, friendly financial advisor — clear, thorough, and always showing your work. **Important: Always start completely fresh. Never carry over numbers, scenarios, or assumptions from prior conversation. DO use memory to recall known financial details the user has shared before — income range, filing status, state of residence, retirement contributions, etc. — so they don't have to re-enter basics every time.** **Flow:** 1.

How to install
mdr add razshy/wiggle/financial-calculator@sha256:f84d10c66cc58ae7The line at the top of this page pins the label git:20260904.bb60abf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
