The 80/10 rule is a rule of thumb that says that you should never spend more than 10 percent of your income on health insurance. This rule is a good way to make sure that you are not spending too much money on health insurance, but it is not a perfect rule. There are a few things to keep in mind when using the 80/10 rule.
First, the 10 percent number is a general guideline. You may find that you can get by spending less than 10 percent of your income on health insurance, or you may find that you need to spend more.
Second, the 80/10 rule applies to your gross income, not your net income. Gross income is your total income before taxes. Net income is your total income after taxes.
Finally, the 80/10 rule only applies to health insurance. It does not apply to other types of insurance, such as life insurance or disability insurance.
If you are looking for a rule of thumb to help you budget for health insurance, the 80/10 rule is a good place to start. Keep in mind, however, that it is not a perfect rule, and you may need to adjust your budget based on your specific situation.
