To the OP's question, it all depends, there are so many variables.
Some questions that might help you figure it out ...
- Do you cook, or eat at restaurants ?
- Do you anchor out, or tie to the dock ?
- Do you sail, or run the diesel ?
- Do you entertain yourself, or go ashore for your entertainment ?
- Do you get along without air conditioning, or require it ?
- Do you get along with refrigeration, or require it ?
- Do you get your fresh water from shore, or make it on the boat ?
- Do you cook with free fuel such as wood, or purchase cooking fuel ?
- Do you catch fish and other seafood, or buy all of your food ?
- Do you get along without high speed Internet, or can't live without it ?
- Do you have a small boat, or a big one ?
- Do you live on a boat that requires little maintenance, or a lot ?
- Do you maintain your own boat, or pay someone to do it for you ?
- Do you sail in inexpensive areas, or pricey areas ?
- Do you store supplies, or buy what is convenient ?
- Do you use blankets as it starts to get cold, or require heating fuel ?
- Do you live with limited solar power, or often run a generator ?
- Etc ...
You said you don't want to live in poverty, what does that mean to you ?
