It was easier for people to understand when measurements were expressed in units they could relate to. In fact, Noah's ark was also built using the same unit of measurement. **300 cubits long, 50 cubits wide, and 30 cubits high** **[![Noahs ark-compared-to-other-ships](https://www.financialplanningindubai.com/hs-fs/hubfs/Noahs%20ark-compared-to-other-ships.webp?width=740&height=271&name=Noahs%20ark-compared-to-other-ships.webp)](https://answersingenesis.org/noahs-ark/thinking-outside-the-box/)Image Source: [https://answersingenesis.org/](https://answersingenesis.org/noahs-ark/thinking-outside-the-box/)** ## Thumb Rules Similarly, we use Thumb Rules or Rules of Thumb to express, understand, remember and apply complex concepts(like personal finance) in our day-to-day lives.

Four times if the existing debt repayments are less than 20% of your income 3. Three times if the repayments are more than 20% ##### 3. Emergency Savings Thumb Rule: 3 - 6 months of income ##### 4. Budgeting Thumb rule:  We have seen this already on [Day 5](https://www.financialplanningindubai.com/blog/day-5-find-the-pattern?hsLang=en-gb).  50/20/30 budget rule #### 5.
