I'm trying to figure out whether it's +EV to maximize my IRA contributions. So we basically need to look at the marginal return of a dollar in my sports betting roll vs. in a IRA.

Someone double-check my math please, but for the IRA here's how I see it... we put a dollar in and since we're doing a traditional IRA it's tax free upfront, so we still have the full dollar. Assuming an expected annual return of 8%, we're looking at $1.08 after one year, $2.16 after 10 years, and a whopping $18.63 when I hit retirement age in...
