I also study statistics, which is actually not difficult. Look at my little method-remember these formulas: 1. Assets = liabilities+owners' equity, profits = income-expenses 2. Net cash flow (NCF) formula: NCF=CFO+CFI+CFF, where CFO represents the net cash flow generated by operating activities and CFI represents the net cash flow generated by investment activities. 3. Activity ratio = activity assets ÷ activity liabilities 4. Quick ratio = (active assets-inventory)/active liabilities 5. Asset-liability ratio = liabilities-assets. 6. Equity multiplier (leverage ratio) = assets ÷ owner's equity = 1 ÷( 1- asset-liability ratio) Debt-equity ratio = liabilities ÷ owner's equity = asset-liability ratio ÷( 1- asset-liability ratio). The greater this value, the higher the financial leverage ratio. 7. Interest multiple = earnings before interest and tax/interest. EBIT (earnings before interest and tax) = net sales-multiple of interest guaranteed operating expenses This target reflects how many times the operating income of an enterprise is the interest on the debt to be repaid. As long as the interest guarantee multiple is large enough, the enterprise will have enough funds to pay interest, and vice versa. 8. Inventory turnover = annual sales cost ÷ average inventory turnover days =365 days ÷ inventory turnover 9. Accounts receivable turnover = sales revenue ÷ average accounts receivable turnover ÷ average collection period =365 days ÷ accounts receivable turnover 10. Total assets turnover rate = annual sales revenue ÷ average total assets turnover rate is an important index to comprehensively evaluate the management quality and utilization efficiency of all assets of an enterprise. The greater the turnover rate, the faster the total assets turnover, reflecting the stronger the sales ability. 1 1. Sales profit rate = net profit ÷ sales revenue 12. Return on assets = net profit/total assets 13. Return on equity (return on equity) = net profit ÷ owner's equity 14. Fv = PV × (6544 N represents the year; I stands for annual interest rate; PV stands for principal or present value. 15.ir=in-P where: in is the nominal interest rate; Ir is the real interest rate; P is the inflation rate. 16.I=PV×i×t where: I is interest; PV is the principal; I is the annual interest rate; T is the interest-bearing time. 17. The formula for calculating the final value of simple interest is: FV=PV×( 1+i×t) 18. Zero coupon bond valuation method: V represents the intrinsic value of discounted bonds; M stands for face value; R stands for market interest rate; T stands for the maturity of the bond. 19. discount factor dt= 1÷( 1+St)t, where St is the spot interest rate. 20. P/B ratio = currency per share/net assets per share 2 1. P/CF = currency per share ÷ Is it difficult to calculate the qualification examination for cash flow funds per share? I am a student studying statistical solutions. 18 1
