Which rate should you use?

The 4% rule came from a 30-year US retirement. If you plan to retire in your forties you are planning for fifty years or more, and most people in that position use 3.25% to 3.5%.

Your FIRE number at 4.00%

$1,750,000

That is 25 times your annual spending of $70,000. At that size, withdrawing 4.00% in the first year and increasing it with inflation each year afterwards has historically been sustainable over a 30-year retirement.
