The daily interest rate of 0.03% means that the interest is calculated at three ten thousandths of the principal of your loan every day. If you borrow 10000 yuan and the daily interest rate is 0.03%, then your daily interest rate is 10000*0.03%=3 yuan. The daily interest calculation formula is: interest = daily interest rate * loan amount = annual interest rate /365. For example, if the borrower borrows 1 0,000 yuan, the annual interest rate is 5.6%, and the daily interest rate calculated according to the above formula is 0.0 1.05%, then the daily interest can be calculated as 1.53 yuan.
Calculation method of daily interest rate:
1. Formula 1: daily interest rate = daily interest ÷ deposit amount X 100%.
2. Formula 2: Daily interest rate = monthly interest rate ÷30
3. Formula 3: Daily interest rate = annual interest rate ÷360
Ten thousand yuan, the daily interest rate is 0.045%, and the monthly interest is 135. The calculation steps are as follows:
Daily interest = principal * daily interest rate;
10000*0.045%=4.5 yuan;
Monthly interest = daily interest * 30;
4.5*30= 135 yuan.
Interest rates are usually divided into annual interest rate, monthly interest rate and daily interest rate. The annual interest rate is expressed as a percentage of the principal, the monthly interest rate as a percentage, and the daily interest rate as a percentage.
Conversion formula of daily interest rate, annual interest rate and monthly interest rate:
1. Daily interest rate = annual interest rate ÷ 360;
2. Monthly interest rate = annual interest rate ÷ 12.
3. Monthly interest rate = daily interest rate ×30
4. Annual interest rate = monthly interest rate × 12
5. Interest = interest product × daily interest rate
When calculating the deposit period, count the heads instead of the tails; Regardless of big month, small month, flat month and leap month, it is calculated as 30 days per month and 360 days throughout the year. The maturity date of all kinds of deposits is calculated by year, month and day. If the account opening date is the missing date in the expiration month, the expiration date will be the last day of the expiration month.
