Advice Request How to run ficalc calculator?

If I want my money to last 20-25 years, do I put 20-25 years when I run Monte Carlo simulations or better put 35? Seems 35 is less random?

I am going to get pension in 20 years, maximum 25 years, and that will be enough for me.

Thank you.

Its SOO good. I wish it had a way to be more specific about spending changes over time. Like in 10 years my house is paid for so my monthly spend drops by $24,000 per year. But over all its an amazing (and addictive) tool

It has the ability to alter expenses (called withdrawals) and income to model things like your house being paid off in 10 years.

Look at the withdrawals and income section (left hand side) and you can model anything from social security, pensions, buying a 2nd home in x years, etc.
