How does the calculation account for different spending frequencies?

The `calculate_expenditure_metrics` tool uses either a 'WEEKDAYS' or 'DAILY' frequency type to determine your total monthly and yearly spending. Tools available: `your_tool_name`.

What interest rate is used for projections?

You can specify any annual return rate, such as a 7% historical S&P 500 average, when using the `project_future_wealth` tool.

Can I set a specific savings goal?

Yes, use the `calculate_savings_milestones` tool to find out exactly how many months or years it will take to reach a target amount.
