Read The Output Correctly
What this planner is best at.
The starting example uses 0% growth so the first result is a contribution schedule. Change the assumption to compare gains or losses; it is not a historical backtest or a predicted Bitcoin return.
The period rate is (1 + annual growth) raised to 1 divided by the contributions per year, minus 1. The tool compounds the starting amount and end-of-period contributions at that same rate. Weekly and biweekly mean exactly 52 and 26 contributions per year.
Use this page to compare routines, not to convince yourself that one fixed growth number is destiny. The strongest use case is figuring out what size and rhythm of contribution still feels realistic when the market stops being comfortable.
After running the planner, the smartest next pages are usually a wallet setup guide, a fee explainer, or a simple exchange checklist.
