How Much of Your Retirement Income Can You Count On?

1. Start by separating income into two jobs

One way to make the retirement-income picture easier to understand is to separate income by the job it performs.

The first job is providing a dependable income foundation.

This is income designed to continue according to defined rules or guarantees.

Depending on the household, examples might include:

• Social Security benefits
• pension income
• income guaranteed by an insurance company through an annuity

The second job is providing flexible income.

This may come from retirement accounts, savings or other assets that you can access as needed.

That flexibility can be valuable.

But the amount available from those resources may change over time.

The important point isn't that one type of income is automatically better than another.

They simply do different jobs.

2. “Dependable” doesn't mean every source works the same way

It's easy to group Social Security, pensions and annuity income together because each can potentially provide ongoing income.

But they aren't interchangeable.

Social Security operates under federal law and program rules.

Pensions depend on the terms of the pension plan.

Annuity guarantees are based on the terms of the insurance contract.

Each source has its own rules, limitations and tradeoffs.

So the useful question isn't:

“Which one is best?”

It's:

“Which portions of my retirement paycheck are designed to continue, and under what terms?”

That distinction matters.

3. Flexible income has a different job

Now consider money held in accounts such as a 401(k), IRA or other savings.

Those dollars may give you considerable flexibility.

You may decide when to take money.

You may adjust how much you take.

You may leave more invested when you don't need it.

And the remaining balance may have an opportunity to continue growing.

But flexibility comes with a different set of questions about withdrawals, account performance, how long the money may need to last and what happens if your needs change.

Those questions matter, but other lessons explore them in more detail.

For this article, the distinction is simpler:

Flexible resources can help provide retirement income, but they aren't necessarily the same as income designed to continue under defined terms.

4. Put the two pieces together

Consider a simplified household that wants:

$7,000 per month of retirement income.

Suppose they expect:

$4,000 per month from Social Security

and

$1,000 per month from a pension.

That gives them:

$5,000 per month of dependable income

before considering their retirement savings.

Their desired retirement paycheck is $7,000.

Their dependable income foundation is $5,000.

That leaves:

$2,000 per month that needs to come from other resources.

This doesn't tell the household what they should do with their savings.

And it doesn't mean all $7,000 needs to be guaranteed.

It simply reveals something useful:

About $5,000 of the $7,000 retirement paycheck is already supported by income designed to continue under its applicable terms.

The remaining $2,000 has a different job.

5. The percentage can be useful too

Once you've identified the different pieces, another number becomes easier to see.

Using the example above:

Desired retirement income:

$7,000 per month

Dependable income:

$5,000 per month

That means roughly 71% of the household's desired retirement paycheck is represented by the dependable-income sources in this simplified example.

The remaining 29% would need to come from other resources.

The percentage itself isn't a score, and there isn't one correct percentage every retiree should have.

Different households may be comfortable with different combinations of dependable and flexible income.

The useful part is understanding your own number.

Then you can decide whether that relationship fits the retirement you're planning.

6. Expenses can give the number more meaning

There is another way to look at the same question.

Instead of starting with total retirement income, consider the expenses you expect to have month after month.

Then ask:

“How much of our regular monthly spending could be supported by income we expect to continue?”

That question can make the concept more practical.

You aren't simply comparing income sources anymore.

You're beginning to connect those sources to the life the income needs to support.

That doesn't mean every recurring expense needs a matching guaranteed-income dollar.

It means you understand which portion of your lifestyle depends on income that may need to come from more flexible resources.

7. Dependability and flexibility both involve tradeoffs

It can be tempting to think of dependable income as automatically better and flexible income as automatically riskier.

Retirement planning is rarely that simple.

Income designed to continue can provide more predictability.

Flexible resources can provide more control over when and how money is used.

Depending on the source, one may offer more access to principal, more opportunity for growth, more ability to adjust withdrawals, or more certainty about the income arriving each month.

Those differences are not flaws.

They are tradeoffs.

The useful question is not:

“How do I make every dollar of retirement income guaranteed?”

And it isn't:

“How do I keep every dollar completely flexible?”

A better question is:

“Which parts of my retirement paycheck do I want to be dependable, and which parts do I want to remain flexible?”

That keeps the focus on the role each source needs to play rather than on choosing a product first.

8. Know what you can count on before deciding what the rest must do

Before deciding what your retirement savings may need to provide, identify the income you already expect to receive.

Start with the retirement paycheck you want.

Then separate the portion designed to continue under its applicable terms from the portion your other resources may need to provide.

You haven't solved every retirement question.

But you've made this one much clearer.
