Probability of success explained

1 min read

Summary

  • Probability of success is the percentage of simulations where your money lasted until your chosen end age.
  • A 90% figure means 900 of 1,000 simulations succeeded.
  • It's a modelling tool, not a guarantee.

What the percentage means

It's the percentage of simulations where your money lasts until your chosen end age without running out. A 90% probability means that in 900 of 1,000 simulations, your portfolio funded your spending for the entire plan. This is a modelling tool, not a guarantee — real life involves adjustments the model cannot anticipate.

Frequently asked questions

Is 90% probability of success good?
It means 900 of the 1,000 simulations funded your spending for the entire plan. Whether that's "good enough" depends on your own comfort with risk — it's a modelling tool, not a guarantee.
Does it guarantee my money will last?
No. It's a modelling tool based on simulated outcomes, not a guarantee — real life involves adjustments the model cannot anticipate.
