The deposit is 1000 yuan in half a year, the annual interest rate is 8%, and the compound interest rate is once a quarter?
Interest rate of interest period I = R / M = 8% / 4 = 2%
Half year effective interest rate ieff = (1 + 2%), # 178; - 1 = 4.04%
Then f = 1000 (F / A, 4.04%, 2 × 5) = 1000 × 12.029 = 12029? How is this 12.029 calculated? And what is the meaning that the interest period is less than the capital collection and payment period?

The interest period is the interval between two interest periods. In this paper, the interest period is a quarter, that is, three months. The capital collection and payment period is the interval between interest payment or principal payment. There are many forms, such as interest payment by stages, one-time repayment of principal, equal repayment of principal and interest by stages, one-time repayment of principal and interest

For a project, the deposit is 1000 yuan per half year with an annual interest rate of 8%. The interest is calculated once a quarter with compound interest. How much is the deposit amount at the end of five years,

In fact, this is a special case of subsequent annuity calculation
If the annual interest rate is 8%, the interest is calculated once a quarter and the compound interest is calculated, the interest rate in the interest period is I = R / M = 8% / 4 = 2%
Half year effective interest rate = (1 + 2%), # 178; - 1 = 4.04%
Then f = 1000 (F / A, 4.04%, 2 × 5) = 1000 × 12.029 = 12029
Personal advice you can look at the financial management textbook. The textbook on compound interest calculation is more clear!

From now on, its annual deposit is 1000 yuan at the beginning of each year, the annual interest rate is 12%, and the compound interest is calculated once a half year. What is the sum of capital and interest at the end of the fifth year
Formula and operation process
Thank you! Online waiting
Using the formula of financial management professional knowledge

1000(1+12%/2)^10+------+1000(1+12%/2)^2=1000(1.06^10+1.06^8+---1.06^2)=1000(1.1236+1.2625+1.4185+1.5938+1.7908)=1000*7.1892=7189.20
