30% down payment is 30% of the total house price, which is paid to the seller when buying a house. The remaining 70% is paid by the bank to the seller, and this part of the money is returned to the bank in the form of monthly payment. Of course, these 70% banks will charge interest.

Calculation method:

Leverage ratio = stock spot price ÷ (warrant price x share conversion ratio).

Extended data:

Leverage reflects the cost ratio of investment stocks to investment warrants. Assuming that the leverage ratio is 10 times, it can only show that the cost of investment warrants is one tenth of that of investment stocks, but it cannot show that when stocks rise 1%, the warrant price will rise 10%.

Operating leverage coefficient:

After obtaining the operating leverage coefficient, assuming that the fixed cost remains unchanged, the operating profit in the planned period can be predicted by the following formula: operating profit in the planned period = operating profit in the base period ×( 1+ production and marketing change rate × operating leverage coefficient). Under the action of a certain fixed cost ratio, the influence of sales volume changes on profits is called operating leverage.
