Value of credit score if you never plan to borrow again?
There's many concrete answers, but there's something circular about your question. The only thing I can think of is that phone service providers ask for credit report when you want to start a new account but I am sure that could be worked around if you just put down a cash deposit in some cases. So now the situation is flipped - you are relying on your phone company's credit!  Who is to say they don't just walk away from their end of the deal now that you have paid in full?   The amount of credit in this situation is conserved. You just have to eat the risk and rely on their credit, because you have no credit. It doesn't matter how much money you have - $10 or $10000 can be extorted out of you equally well if you must always pay for future goods up front. You also can't use that money month-by-month now, even in low-risk investments. Although, they will do exactly that and keep the interest. And I challenge your assumption that you will never default. You are not a seraphic being. You live on planet earth. Ever had to pay $125,000 for a chemo treatment because you got a rare form of cancer? Well, you won't be able to default on your phone plan and pay for your drug (or food, if you bankrupt yourself on the drug) because your money is already gone. I know you asked a simpler question but I can't write a good answer without pointing out that "no default" is a bad model, it's like doing math without a zero element. By the way, this is realistic. It applies to renting in, say, New York City. It's better to be a tenant with credit who can withhold rent in issue of neglected maintenance or gross unfair treatment, than a tenant who has already paid full rent and has left the landlord with little market incentive to do their part.
