What it means
Many people build up savings over a working life and then need to turn them into income. Instead of selling everything or relying only on dividends, they can set up a plan that sells just enough each period to pay a set amount.
The investor receives a predictable payment, and the rest stays invested. The main choices are the amount, the frequency and the investments to sell.
A common guide is to withdraw a percentage of the starting balance each year, often in the range of 3% to 5%, and to adjust for inflation over time. The right rate depends on the investor's age, risk tolerance and other income.
Returns and timing matter a great deal. If markets fall early on while withdrawals continue, the portfolio can be depleted faster than expected, which is known as sequence of returns risk.
Withdrawing the same amount in a falling market means selling more units at low prices, and those units cannot benefit from a later recovery. Tax treatment depends on the country and the type of account.
Withdrawals may include both the original capital and gains, and each sale may create a taxable event outside tax-sheltered accounts. Investors should work out the after-tax income, not only the headline withdrawal.
An SWP differs from an annuity, which is a contract with an insurer that pays a guaranteed income, often for life. With an SWP the investor keeps control and ownership of the assets but takes the risk that they run out.
Many people hold some of each, using guaranteed income for essential costs and a withdrawal plan for flexible spending. Flexibility rules can make a plan much more durable.
Some investors skip the inflation increase after a year in which the portfolio fell, while others set a ceiling and a floor on the annual amount so that spending adjusts gradually. Even small adjustments of this kind reduce the chance of running out of money, because fewer units are sold when prices are low.
In practice
Real-world examples.
Example
A retired teacher with a $600,000 fund sets up a monthly withdrawal of $2,500. This equals $30,000 a year, or 5% of the starting balance, and she reviews the rate every year.
Example
A small business owner who has sold his company invests the proceeds and arranges quarterly withdrawals of $15,000. He uses the money to cover living costs while leaving the remainder invested.
Example
A charity sets up a withdrawal plan from its reserve fund to cover scholarships. The trustees set the annual amount at 4% of the average fund value over the last three years to smooth out market swings.
Formula
Calculation
Annual withdrawal = Portfolio value x Withdrawal rate
Monthly withdrawal = Annual withdrawal / 12
Suppose a retiree has $480,000 and chooses a 5% withdrawal rate.
Annual withdrawal = $480,000 x 0.05 = $24,000
Monthly withdrawal = $24,000 / 12 = $2,000
If the portfolio earns 6% over the year, ignoring timing, the closing balance is about $480,000 x 1.06 - $24,000 = $508,800 - $24,000 = $484,800.
Because the return of 6% exceeds the 5% withdrawal rate, the balance grows slightly, but in a year with a return of 0%, it would fall to $480,000 - $24,000 = $456,000.Case study
Seen in the real world.
Copperfield Family Trust is an illustrative, fictional trust that holds $1,000,000 to support a family member's living costs. The trustees set up an SWP of $4,000 a month, which is $48,000 a year, or 4.8% of the starting value.
In the first year markets fell 10%, so the portfolio fell to about $1,000,000 x 0.90 - $48,000 = $852,000. The trustees saw that continuing the same payment would be 5.6% of the lower balance, because $48,000 / $852,000 = 5.6%.
In the illustrative follow-up they cut the payment to $3,400 a month for a year, which is about 4.8% of the reduced balance, and restored it when markets recovered. This flexibility helped the fund last longer than a rigid plan would have.
Watch out
Common mistakes.
- Choosing a withdrawal rate that is too high, which can exhaust the portfolio too soon.
- Ignoring inflation, so that the spending power of fixed payments falls over time.
- Forgetting tax on withdrawals, which reduces the income actually available to spend.
Questions
People also ask.
What is the difference between an SWP and an annuity?
An SWP pays from an investment you own and can run out, while an annuity is a contract that pays an agreed income, often for life.
Can I change the amount?
Usually yes, and many investors review the amount each year to reflect markets, spending needs and inflation.
What is a safe withdrawal rate?
There is no single safe figure, but rates of 3% to 5% of the starting balance are commonly discussed, and the right rate depends on circumstances.
