“That which is measured, improves”Through this process, there is also great learnings, e.g. through the "When can I retire?" page at Netwothify we can see the significant impact on the savings rate.
Networthify requires that we input the following information :
- Annual after-tax income
- Current saving rate
- Current portfolio value
- Assumed 5% real annual return on investment
- You will withdraw about 4% of the portfolio each year to spend
This simple yet powerful concept has also been explored by Mr Money Moustache:

我在網上收集了一些小工具,可以幫助我們估計我們到FI需要的effort 和時間。
而這個估計的過程其實很是好的學習,例如通過Netwothify在“When can I retire?”的頁面,我們可以看到對儲蓄率的重大影響。
Networthify要求我們輸入以下信息:
- 年度稅後收入
- 目前的儲蓄率
- 當前的組合價值
- 假設每年實際投資回報率為5%
- 每年將提取約4%的投資
Mr Money Moustache 也探討了這個簡單而強大的概念:
