Part-Time Retirement Calculator

Last updated July 2, 2026

Part-time retirement — working reduced hours or on a flexible schedule while drawing on retirement savings for the difference — is a growing alternative to the hard stop of traditional retirement. It serves multiple financial functions simultaneously: income from part-time work reduces the portfolio withdrawal rate, allowing savings to last longer; delayed full Social Security claiming allows the benefit to grow; and continued engagement tends to support better health outcomes, which matters for longevity planning.

The financial math of part-time retirement is straightforward but revealing. A retiree who needs $5,000 per month to live and earns $2,000 per month in part-time income needs $3,000 from savings — a 3.6 percent withdrawal rate on a $1 million portfolio versus 6 percent if fully retired. That reduction in withdrawal rate dramatically extends portfolio longevity. There's a Social Security earnings test consideration: before reaching full retirement age, earning more than $24,480 in 2026 while collecting Social Security results in a temporary benefit reduction of $1 for every $2 earned above that threshold, though those reductions are later credited back when you reach full retirement age. After full retirement age, there is no earnings limit.

Part-time retirement is often the financially optimal middle path between working full-time and fully retiring — it reduces withdrawal pressure, delays Social Security, and preserves more flexibility. Model what your savings need to provide if you earn $1,000, $2,000, or $3,000 per month in part-time income, and see how dramatically that changes the sustainability of your retirement.
