Rule of 70Rule of 70 is a short-cut method of an economy’s growth accounting which tells us that if an economy’s annual growth rate is g, its output/GDP will double in 70/g years. For example, if an economy grows by 2.3% constantly, rule of 70 tells us that its total product...
it is not difficult to obtain a formula for the exact doubling time, the rule of 70 remains useful when finding quick estimates and doing mental math. The Rule of 70 says that the doubling time is close to70%r. For example, ifr=5%, thent≈70%5%=0.700.05=14...
so, to double the amount, 70/10=7 years(两倍)，保持10%增长，再翻上一番，公式仍然是70/10=7 years。所以是14年。
the rule of 70 applies only to amounts that have compounding growth. An example is an investment with compounding interest, which means interest is also earned on the interest added to the principal. This compounding process allows exponential growth, without which the rule of 70 will become ina...
Example Here’s an example table of the way a rule of 72 calculator works. As you can see, the first column represents the annual rate of investment that will be compounded at the end of every year. The second column shows the number of years it will take for the investment to double...
Rule of 72 Calculator The Rule of 72 Calculation Example The Rule of 115 Calculation Example What is the Rule of 72? The Rule of 72 is a shorthand method to estimate the number of years required for an investment to double in value (2x). In practice, the Rule of 72 is a “back-...
Example # Add a rule to ACL6 3000 to deny the packets with the destination UDP port number that is greater than 128 from fc00:1::1 to fc00:3::1. <HUAWEI> system-view [HUAWEI] acl ipv6 3000 [HUAWEI-acl6-adv-3000] rule deny udp source fc00:1::1 64 destination fc00:3::1 ...
This is useful, for example, if you want to share and get comments on the business rule from a team member. Use the mini-map to navigate quickly to different parts of the process. This is useful when you have a complicated process that scrolls off the screen. As you add conditions, ...
The Rule of 70 can estimate how long it would take a country's gross domestic product (GDP) to double. Instead of estimating compound interest rates, the GDP growth rate is the divisor of the rule. For example, if the growth rate for China is estimated as 10%, the Rule of 70 predict...
The Rule of 72 The rule of 72 is a simple method to determine the amount of time investment would take to double, given a fixed annual interest rate. To use the rule of 72, divide 72 by the annual rate of return. For example, assume an investor invests $20,000 at a 10% fixed a...
