Question

How long will it take to spend 1 billion dollars at 10k a day?

Answer 1

With or without interest?

At $10K per day you are spending $3652500 per annum. This is 0.36525% of your $1 BN per annum.  assuming nominal (greater than .37%) interest you would not ever spend it all providing you gave yourself an initial period to receive your first interest payment in.

With no interest then obviously 100000days would be the amount of time until all of your money was gone.274 years!!

Answer 2

quite a while. Is your question meant to be rhetorical? seems like it is.
