Usually the DCA method will be based on your income, because if you invest regularly. Then you can invest weekly or monthly. Estimated average monthly expenses in your household are $100, and $170 if you are salaried. Then you can invest part of your expenses here and meet the basic needs, with the rest of the money you can invest.
In this case, it is most important that you use an emergency fund, because people can get sick at any time. That is why you must use emergency fund so that your investment does not get lost.
DCA is a strategy for investing in which you can invest consistently every day, you can invest consistently every hour, you can invest consistently every month or every week. If you think you will invest 10 dollars every day then at the end of the week your investment amount will be 70 dollars and at the end of the month your investment amount will be 300 dollars. I used to know that investing earlier means we need to accumulate a lot of money before we invest but this strategy of investing has changed our entire thinking of investing and made investing much easier. In this investment strategy investors can easily invest from any income or from any profession. I think every investor is satisfied with this investment strategy.
