RMD Calculator

Starting at age 73, you must withdraw a minimum amount from your retirement account each year.

What this calculator does

RMD = Account Balance / IRS Life Expectancy Factor.

When to use this calculator

Use this calculator before making any financial commitment that depends on this type of calculation. Running the numbers in advance lets you evaluate options without the pressure of a live negotiation or decision deadline.

Common mistakes

The most consequential mistake is comparing financial figures that are not on the same basis — gross versus net, before-tax versus after-tax, or nominal versus inflation-adjusted. Always check whether figures you are comparing use the same definition.

Real-world scenarios

A first-time buyer models three scenarios before making an offer: 10%, 15%, and 20% deposit on a £280,000 property. The calculator shows exactly how the monthly payment and total interest cost change with each deposit level, making the decision visible rather than speculative.

Frequently asked questions

When do RMDs begin?

Age 73 (or age 75 for those born after 1959).
