The drawdown calculator simulates how long your retirement pot lasts when you draw down a set income each year.
It accounts for investment returns, inflation, and the State Pension topping up your income from your State Pension age.
A 4% starting withdrawal rate is the textbook safe rate, but UK retirees often use 3% to 3.5% for extra margin.
The biggest risk is sequence of returns - poor markets in your first decade of retirement can shorten the life of your pot dramatically.
