How to Calculate Loan Amortisation with OpenClaw
Calculate loan amortisation with OpenClaw and ToolRouter. Batch loan analysis for portfolio management.
Tool
OpenClaw calculates amortisation schedules for multiple loans in batch. Analyse a portfolio of outstanding loans, compare remaining balances and interest exposure, or generate consistent repayment data for all borrowers in a book — without building separate calculations for each loan.

Once connected (see setup above), use the Financial Calculator tool:
- Provide loan parameters for each loan in the portfolio
- Ask: "Generate amortisation schedules for all loans and show remaining balances"
- OpenClaw returns schedules with current period position for each loan
- Ask: "What is total interest exposure across all loans for the next 12 months?"
Example Prompt
Try this with OpenClaw using the Financial Calculator tool
Generate amortisation schedules for three loans: $150k at 4.5% for 15 years, $300k at 5.5% for 30 years, $80k at 6% for 10 years. Show current period principal and interest for each, plus the total remaining interest exposure across all three.
Tips
- Track current period position for each loan to build accurate outstanding balance reports
- Run batch calculations at month-end to update portfolio interest exposure figures
- Ask for the payoff date for each loan given current payment schedules to plan cash flow
