Embodiment 1

[0042] The present invention provides a calculation soft ruler for calculating income parameters, including income ruler 1 and time ruler 2, the income ruler and time ruler are closely connected in the left locking buckle 3 and the right locking buckle 4 and can twitch left and right. The locking buckle and the right locking buckle can lock the income ruler and the time ruler and straighten them in parallel. The anti-off cap 5 is located at the end of the income ruler and the time ruler to prevent the ends of the income ruler and the time ruler from passing through the locking buckle The magnifying glass 6 is set on the outside of the income ruler and the time ruler and can slide in parallel. It is characterized in that: the front of the calculation soft ruler, that is, the income ruler and the time ruler are respectively engraved with numbers, and the numbers on the income ruler indicate year, month and day. Yield or total income after a time period, the digital range on the i...

Embodiment 2

[0044] Embodiment 2, using the calculating soft ruler of the present invention to measure the total income.

[0045] Using the calculation soft ruler in Example 1, Xiao Wang deposits 20,000 yuan in the bank for 1 year for regular financial management, and the annual interest rate of lump sum deposit and withdrawal is 3.25%. Find Xiao Wang's total income after 5 years of regular deposits.

[0046] The annual interest rate is 3.25%, and the annual growth rate is 1+3.25%=1.0325;

[0047] Such as figure 2 As shown, twitch the income scale and the time scale so that the scale line marked "1" on the time scale is aligned with the scale line of "1.0325" (1+3.25%), which is the annual interest rate plus 1 on the income scale, and lock the left Tighten the buckle to the left of the alignment line, straighten the earnings scale and time scale to the right of the left buckle, and move the right buckle to the right of the scale marked "5" (5 years) on the time scale , and tighten the rig...

Embodiment 3

[0049] Embodiment 3, using the calculating soft ruler of the present invention to measure the rate of return per unit time.

[0050] Using the calculation soft ruler in Example 1, Xiao Li bought Fund A with 100,000 yuan, and the net value of the fund after 3 years is 121,000 yuan. Find the annualized rate of return for Xiao Li to buy the fund.

[0051] After 3 years, the net value of the fund is 121,000 yuan, the base is 100,000 yuan, and the total return rate is: (12.1-10)÷10=0.21;

[0052] Such as image 3 As shown, twitch the income scale and the time scale, so that the scale line marked "3" (3 years) on the time scale is aligned with the total return rate on the income scale plus 1, that is, the scale on the income scale is "1.21" (1+0.21) Tighten the right locking buckle on the right side of the alignment line, the income scale and time scale are straightened on the left side of the right locking buckle, move the left locking buckle so that it is on the scale marked "1" ...

Abstract

The invention relates to a calculation tape rule for measuring profit parameters, and a use method thereof. The calculation tape rule comprises a profit rule and a time rule, and is characterized in that the front surface of the calculation tape rule (ie., the profit rule and the time rule) is respectively engraved with numerals, wherein the numerals on the profit rule represent the year profit rate, the month profit rate, the day profit rate or the total profit after a fixed time period, the time rule is a time period ruler, and the unit is year, month, day, ten years or a hundred years. According to the present invention, when a profit rate per unit time and a profit time period are known, the total profit after expiration of a time period can be measured with the calculation tape rule, when the total profit and a profit time are known, a profit rate per unit time can be measured, and when a profit rate per unit time and the total profit are known, a time required by obtaining of the total profit can be measured; and the calculation tape rule has characteristics of wide numeral range, rich data, convenience, low cost, easy carrying, and strong practicality.

Description

technical field [0001] The invention relates to a calculating soft ruler, in particular to a calculating soft ruler for measuring and calculating income parameters and a using method thereof. Background technique [0002] The slide rule or slide rule was invented between 1620-1630 using logarithmic principles and improved as needed, making it the most widely used mathematical tool before calculators / computers became common. [0003] Although with the development of science and technology, more efficient and convenient tools, such as computers or calculators, have gradually replaced this old-fashioned mathematical tool, but this old-fashioned slide rule is still inseparable in some specific fields. For example, in the field of financial planning, when people invest or borrow money, they often need to know the interest rate to know the income after many years, or the repayment period when they need to know the interest rate and the total amount, and so on. When using a comput...
