The actuarial calculation will show that the amount you spend now is exactly equal to the present value of periodic amounts spent into perpetuity, if your assumptions about future rates of return hold forever.

My personal hypothesis is that spending is better for the economy than investment, so I would prefer to spend 10% and invest 90% for 20 years, then spend the remainder, than to spend 3% and invest 97%, forever.
