1. What is Daily Interest Rate?

The daily interest rate is the interest rate calculated on a daily basis, derived from the annual interest rate. In the UK financial context, this is commonly used for daily compounding interest calculations, credit card interest, and short-term loan calculations.

2. How Does the Calculator Work?

The calculator uses the standard UK daily rate formula:

Where:

• \( Annual\ Rate \) — Annual interest rate expressed as a decimal (e.g., 0.05 for 5%)
• \( 365 \) — Number of days in a year (UK standard)
• \( Daily\ Rate \) — Resulting daily interest rate as a decimal

Explanation: This calculation assumes a 365-day year, which is the standard convention used in UK financial calculations for daily interest rate conversions.

3. Importance of Daily Rate Calculation

Details: Daily interest rate calculation is essential for accurate financial planning, understanding the true cost of borrowing, calculating daily compounding interest, and complying with UK financial regulations that require transparent interest rate disclosures.

4. Using the Calculator

Tips: Enter the annual interest rate as a decimal value (e.g., enter 0.12 for 12% annual rate). The calculator will automatically compute the equivalent daily rate using the UK standard 365-day year convention.

5. Frequently Asked Questions (FAQ)
