How This Page Helps You Compare Options
The calculator is tuned for finance-style decisions: it breaks results into components, shows a scenario ladder, and surfaces the gap that usually matters most for a real-world choice.
Use the first KPI to see whether the current plan leaves an uncovered loss, tax shortfall, or cash-flow mismatch.
Review the chart and scenario table to compare premium, deductible, withholding, or payout changes without losing context.
Adjust one assumption at a time so you can see whether the decision is robust or just dependent on one optimistic input.
This mode shapes the inline chart inside the calculator so the output looks more like a finance decision dashboard than a plain result box.
