At 57 4.5-5 million would be considered a no worries retirement for most everyone with a $200,000 annual budget using the traditional 4% rule. It really all depends on your spending habits and if you live in a high cost of living location if that number works for you. If your house is paid off and all you need to worry about are insurances, property taxes, maintenance, utilities etc, a lot of that pot becomes fun money. However, if you have a large house to maintain those costs can be very expense as a new roof on a 4000K sq ft house is about 100K by us vs $25k for a 1400 sq ft house. I think it's important to sit down together as a couple and map what you see as your wants, needs and goals in retirement and once you have that it's easier to focus in on a number that you need to achieve. With so many financial calculators available on the internet, I don't think it's necessary to sit down with a financial planner if you have been maintaining your assets and investments on your own all along and are financially savvy. Too many just want a cut of off the top of your investments without doing anything different than you can do yourself.
