Monarch Money → ProjectionLab Sync

Sync Monarch Money account balances into ProjectionLab with one click. Preview every change first. No servers, no tracking.

Stop retyping balances. If you track your money in Monarch Money and plan your financial future in ProjectionLab, this extension keeps ProjectionLab's current balances up to date in one click. HOW IT WORKS 1. Log in to Monarch Money in your browser — no API token needed, the extension uses your active session 2. Paste your ProjectionLab Plugin API key (official ProjectionLab Plugin API) 3. Link your accounts once — matching names are auto-linked for you 4. Click Sync. Done. The popup shows a full preview before anything changes: current ProjectionLab balance, new Monarch balance, and the difference for every account. Untick anything you don't want to sync. FEATURES • One-click sync — updating every balance takes seconds • House + mortgage stay in sync — a ProjectionLab asset with an attached loan (house + mortgage, car + auto loan) maps as two separate fields, so Monarch's home value and mortgage balance each sync to the right place and your equity stays correct • Preview before syncing — see old vs. new balances with change amounts first, and exactly which ProjectionLab account and field each balance goes to • Selective sync — checkboxes per account • Auto-link by name — plus a full mapping editor with search, sort, and type filters • Supports savings, investment accounts, assets, and debts • Cross-device settings — your mappings follow your Chrome profile • Works with Chrome, Arc, Brave, and Edge PRIVATE BY DESIGN Your financial data never leaves your browser: • No backend servers — the extension talks only to Monarch Money and ProjectionLab directly • No analytics, tracking, or telemetry of any kind • Your ProjectionLab API key is stored in Chrome's extension storage, nowhere else • Your Monarch password is never seen or stored — the extension reads balances through the session you already have open • 100% open source — audit the code on GitHub: https://github.com/batkison/monarch-projectionlab-sync PERFECT FOR FIRE planners, retirement planners, and anyone doing serious financial planning who uses Monarch Money for day-to-day tracking and ProjectionLab for long-term projections, Monte Carlo simulations, and net worth modeling.
