This calculator is a starting point, not envelope budgeting. Lane focuses on tracking first: sync accounts, categorize transactions, and review net worth before full budget rules ship.
When you are ready to move beyond a monthly budget spreadsheet, Lane connects through Plaid and keeps your dashboard current.
