Ask Bill

This is your space to ask me questions, which I welcome.

Let’s establish some ground rules:

  1. I can only answer general questions about my research, my website, my book, and the 4.7% Rule. I can’t answer questions specific to your personal financial situation.
  2. Keep it clean. Keep it on topic. Keep it respectful.
  3. I will post my answer to your question on this board for all to see, in the hopes it helps many people. I will hide your identity.
  4. You may comment on my answer or others' comments. If you do so, please don’t forget rule #2. I will diligently remove comments I deem inappropriate.
  5. I’ll answer questions as soon as I can. If I get swamped, I apologize in advance for any delay.

Now: Ready, Aim and Fire those questions!

Thanks,

Bill Bengen
