Quick answer: how much do you need to retire?
For a retirement from 65 to 90, you typically need savings of about 18 to 25 times your first-year spending in retirement, with that spending grown by inflation from today, minus whatever pensions will pay. For example, $4,000 a month today is about $116,500 a year in 30 years at 3% inflation, so roughly $2.1 to 2.9 million at retirement before pensions. Retiring earlier, or planning to 95, needs more.
How this retirement calculator works
- Your spending at retirement. Today's monthly spending grows with inflation until your retirement age.
- Your target. We add up every year of spending from retirement to your plan age, allowing for what the money earns while it waits: the first 10 years in bonds and cash, later years in a mix with more stocks.
- What you already have. Your current savings grow at the returns you enter.
- Monthly investment. We find the monthly amount, rising each year, that closes the gap, with stocks reduced gradually as retirement gets closer.
- Will it last? We check the plan at expected returns and after a 35% stock crash in your first year.
Frequently asked questions
How much money do I need to retire?
It depends on what you spend, inflation and how long retirement lasts. As an example, $4,000 a month today becomes about $9,700 a month ($116,500 a year) in 30 years at 3% inflation. For a retirement from 65 to 90, that typically means savings of roughly 18 to 25 times your first-year spending, less any pension or state benefits. Enter your own numbers above for an exact figure.
How do I calculate how much I need for retirement?
Take your monthly spending today and grow it with inflation until your retirement age. Add up every year of spending from retirement to your plan age, still rising with inflation, and discount each year by the return the money earns until it is spent. That total is your target. Subtract what your current savings will grow to, and the rest is what your monthly investing must build.
What inflation rate should I use?
Around 2 to 3% is a common long-term assumption in developed economies, and higher in many emerging markets. Medical costs usually rise faster. If you are unsure, test 1 percentage point higher to see how much more you would need.
Until what age should my retirement plan last?
Plan until at least 90. Running out of money at 85 is a much bigger problem than leaving some behind, and people who reach 65 in good health often live well into their late 80s or 90s.
Should I include state pensions or Social Security?
Yes, if you expect them. This quick calculator assumes no other income, so it shows the full amount your own savings must cover. The financial planner lets you add pensions, rental income or part-time work from any age, which lowers the savings you need.
Why increase my monthly investing every year?
Raising what you invest by 2 to 5% a year, in line with pay rises, can cut the starting amount you need by a lot, because later, larger contributions do much of the work.
Is my data stored anywhere?
