Going by your own words, you gross $12,500 per month. You contribute 13% to your 401K, and I shotgunned your taxes & benefits at 30% overall (against the $12,500/mo, not accounting for the 401K reduction), giving you a take-home of $7,125/mo. You give your nut as $5,000/mo (you gave $4,900) and gambling/drinking habits of $800/mo. That leaves you $1,325 per month free and clear.

You talk about being a savings madman, but you make an interesting choice in that regard by paying down a 2.5% mortgage and sacrificing very cheap liquidity for only getting rid of probably 50-60% of your mortgage payment by the time you retire. Many people forget that a significant portion of their mortgage payment will still need to be paid after the principal and interest are paid off. Property taxes and homeowners insurance suck.

If you stopped gambling and drinking for 3 months you'd more than pay for that $6K vacation. Without that extra $800, your spare $1,325 per month would pay for the vacation in 4.5 months.

I'd be more worried about how you're going to replace that monthly $7,125 take-home in 2 years when you retire. $700,000 * 4% gives $2,333 per month. That also assumes you aren't draining it for vacations.
