Usually, in a conclusion, you wrap up what you have been writing about the whole time. So, a conclusion is basically a summary of the whole text. You can introduce new ideas for the reader, but it is usually inadvisable. In a couple of sentences, you should finish your text, referring to the previous paragraphs and just wrap it all up nicely.
The rule says that you should spend 50% of your income on your living expenses, like your rent and car payment. You should put 20% of your income in savings, whether that’s for a rainy day fund or a down payment on a house. For the remaining 30%, put it toward personal expenses like a night out with friends or a weekend getaway.
Because the 50/20/30 rule is a guideline, there is some flexibility. You can adjust the percentages based on your unique circumstances. The main idea is to limit your living expenses to roughly 50% of your income. That way, you’ll have enough leftover for your savings and fun expenditures.
