Is there ever a time when paying monthly installments is better than paying the full price upfront?

I take 0% interest fee payments when there are no hidden or frictional costs. I use the excess to invest into equities and manage my investment portfolio better. I only do this for items which I can pay off fully from the beginning to avoid late-fee charges.

As long as the interest rate that is tagged to the total price is lower than parking your money elsewhere, it is better to pay monthly installments.

For installements that incur 0% interest, it is recommended to pay by monthly as the accumulated interest earned via high-yield savings account or dividends earned via bonds or stocks will much exceed.
