FAQ

Should I include my super / 401k in this calculation?

In short: yes. We believe there is no reason not to include your retirement accounts in these calculations unless all of your money is locked away in these accounts. I’ve covered this question in our FIRE FAQ #2 in more detail.

What does “inflation-adjusted return” mean?

That’s your expected investment return after inflation. So if you assume your return will be 8% per year and inflation will be 3% per year, your inflation-adjusted return is 5%.

How high will my investment return be? Which SWR should I use?

I’ve covered these assumptions in our Coast FI article (under the “assumptions” section): Coast FI Explained
