It visualizes your future asset growth with graphs and tables, so you can track principal, interest, and balances for each period. Key Features 1. Future Value Calculator Enter your initial principal, regular contributions, and interest rate to project your total future assets. Add a withdrawal amount to simulate scenarios where you draw down principal while continuing to invest. 2. Contribution/Withdrawal Calculator Figure out how much to save monthly (or annually) to hit your target—or how much you can withdraw each period. 3. Time to Goal Calculator Calculate how many years it will take to reach your goal based on your contribution amount and interest rate. Supports withdrawal scenarios too. 4. Required Rate Calculator Find the annual return rate needed to achieve your target amount. Features - Results are visualized with graphs and tables, so you can easily check details by period. - Supports annual/monthly compounding, as well as accumulation and withdrawals. - High-precision decimal calculations minimize errors.

"If I contribute $1,000/month to my 401(k) with 50% employer match, what's the balance at retirement?" "If I open a 529 plan with $200/month for 18 years, how much for college?"
