Copilot generates amortisation schedules as structured arrays ready for use in mortgage calculators, loan comparison tools, or financial planning applications. Pull a complete schedule with every payment period as a typed data structure, and build display components or export logic directly from the output.

Steps

Once connected (see setup above), use the Financial Calculator tool:

  1. In Copilot Chat: "Generate an amortisation schedule for a £200,000 loan at 5% over 20 years"
  2. Copilot returns the full payment schedule as structured data
  3. Ask: "Generate a React component that displays this amortisation schedule as a table"

Example Prompt

Try this with Copilot using the Financial Calculator tool
Generate a full amortisation schedule for a $300,000 loan at 5.5% over 30 years. Return as JSON array with period, payment, principal, interest, and balance fields for each month.

Tips

  • Use the structured array to seed amortisation chart components with real calculation data
  • Ask Copilot to generate CSV export functionality from the amortisation data array
  • Build loan comparison features by generating two schedules with different rates and diffing the cumulative interest
