How is the interest rate calculated?

The rate is determined by taking the Bank of England base rate applicable during each period and adding a fixed margin of 8%.

What is the compensation fee?

The fixed compensation amount depends on the debt size: £40 for debts up to £1,000, £70 for debts up to £10,000, and £100 for anything above.

Which tool should I use for a full breakdown?

You should use the `total_claim_summary` tool to get the interest, compensation, and total claim value in one response.
