How is the interest calculated each month?

The monthly contribution is added to the previous balance at the start of the month, and then the periodic interest (annual rate divided by 12) is applied to that new sum.

What happens if I request a period longer than 600 months?

The system implements automatic sampling. For periods exceeding 600 months, the `generate_monthly_table` tool will provide an annual view (every 12th month) to ensure performance and readability.

Can I find out when my savings will reach a specific goal?

Yes, you can use the `find_target_balance_month` tool to calculate exactly which month and year your investment reaches your target balance.
