Key points
- A retirement income gap is when your income falls short of actual expenses in retirement.
- Causes include longer lifespans, rising healthcare costs, inflation, and investment or Social Security timing decisions.
- Avoid shortfalls by saving more, working longer, delaying Social Security, and seeking financial advice.
- Manage income by using guaranteed sources for essentials and investments for discretionary spending.
You’ve taken the important first step toward a comfortable retirement by saving and planning for your future. You may even have a budget in mind for your golden years and an understanding of how your retirement income — from sources such as Social Security, pensions or a 401(k) — can help fund that dream. But rising costs and unexpected expenses can mean your retirement income may fall short of your actual needs. The difference between your retirement income and actual expenses is known as a retirement income gap.
What causes a retirement income gap?
As people live longer, retirement can last decades, increasing the risk that savings won’t stretch far enough to cover expenses, according to Kiplinger. The publication notes that rising healthcare costs — often reaching well into six figures over a retiree’s lifetime — along with inflation can erode purchasing power and make everyday living more expensive. Kiplinger also reports that planning decisions, such as when to claim Social Security and how to invest, play a critical role in determining whether retirement income will be sufficient over time.
How can I avoid a shortfall?
Despite these threats to your retirement budget, it's possible to plan for a gap. A financial professional can help review your retirement plan and suggest strategies to avoid retirement income gaps.
Strategies such as boosting pre-retirement savings, planning on working longer, or delaying Social Security payments can all help decrease the likelihood of a shortfall, says Time.
It's also important to understand which sources of income you'll use toward essential expenses, such as food and housing, and which you'll use for non-essential discretionary spending.
Experts at Time and Kiplinger recommend earmarking guaranteed retirement income streams, such as Social Security or pensions, toward essential expenses. An annuity is another good way to secure a steady stream of lifetime income to cover essential expenses during retirement. By combining an annuity with other guaranteed sources of retirement income, you can have peace of mind knowing your essentials are covered.
The funds you've designated for discretionary spending can be invested in assets with greater market exposure and opportunity for growth, such a stocks, Exchange Traded Funds (ETFs), or mutual funds, says Kiplinger. This can enable you to keep up with rising costs and better handle unexpected expenses. And by having multiple sources of retirement income, you reduce the overall risk to your budget should any single source falter.
Income gaps in retirement can't always be foreseen, but there are ways to reduce the risk that they'll affect your budget. And with a little planning, you can have greater comfort and financial freedom during your golden years.
