I know quite a few posts like this one have been made, but more specific in detail on two expenses I am having a little difficulty calculating. So I am in early 20s right now and wanting to retire by my 40s, but I want be able to travel the world a couple times each year. Also airsoft is my big expense hobby so I still plan on buying a couple guns, and, gas, etc, each year.

No savings currently due to complications earlier in life. I plan socking away 20k first five years, 30k next five years, etc, up to 50k a year for the last 5. However, with an estimated return rate 5% I would save up around 1.16 million roughly. Currently including inflation and problem of on going healthcare. Basically the advice I am asking for is do my fellow brothers think this will be enough to support the lifestyle I am looking for? Also any other possible suggestions to be able to retire sooner Or get better expected return percentages?
