What is the general interest rate of investment funds?

Investment and financial management means that investors can maintain and increase their value through reasonable arrangement of funds. Interest rate means the ratio of interest amount to principal in a certain period, usually expressed as a percentage, calculated on an annual basis, which is called annual interest rate.

The profit rate of working capital refers to the ratio of the total profit realized by the fixed working capital occupation of an enterprise in a certain period of time. The profit rate of working capital reflects the economic effect of working capital utilization. The more profits a unit can realize from its fixed working capital, the better the utilization effect of its fixed working capital, and vice versa.

Earnings before interest and tax = 200× 20% = 400,000 yuan;

Interest payable = 200×1÷ (4+1)× 8% = 32,000 yuan;

Pre-tax profit = 400-320 = 368,000 yuan;

Payable enterprise income tax = 36.80× 33% =12.1.44 million yuan;

Self-owned funds (owner's equity) = 200× 4 ÷ (4+ 1) = 1.6 million yuan;

Net profit = 36.80-12.144-3.20 = 21.456 million yuan.

Profit rate of self-owned funds = net profit ÷ average owner's equity × 100%

=2 1.456÷ 160× 100%= 13.4 1%

Profit rate of working capital = total annual profit/average annual balance of working capital * 100%.
