When deciding when to claim Social Security benefits, you’re faced with a range of considerations that will impact your financial well-being throughout retirement. Two of the most important factors are your time horizon and your discount rate. By understanding how these elements influence the present value of your Social Security benefits, you can make more informed decisions and maximize your retirement income.
In this article, we will explore what time horizon and discount rate mean, how they affect your Social Security benefits, and how you can apply these concepts to your own situation.
What Is the Time Horizon?
Your time horizon is the length of time over which you expect to receive Social Security benefits. Essentially, it depends on your life expectancy and health status. The longer your time horizon, the more beneficial it typically becomes to delay claiming your benefits, as the monthly payment amount increases for each year you wait.
For example, delaying from age 62 to age 70 can boost your benefits by approximately 8% per year past your full retirement age. If you expect to live into your late 80s or beyond, this delay can result in significantly higher cumulative benefits.
Discount Rate vs. Real Discount Rate: What’s the Difference?
The discount rate is the rate at which you discount future benefits relative to receiving money today—it represents the opportunity cost of waiting for higher payments rather than taking the money immediately. This rate reflects your personal preferences for current versus future income, influenced by factors such as investment opportunities and risk tolerance.
It’s also important to distinguish between the nominal discount rate and the real discount rate. The real discount rate takes into account the effects of inflation, giving you a more accurate picture of the purchasing power of future benefits compared to present dollars.
For example:
- If inflation is 2%, and you use a nominal discount rate of 6%, your real discount rate is closer to 4%. This lower rate helps you understand the true value of delaying your Social Security benefits when inflation is factored in.
Present Value Analysis of Claiming Social Security Benefits
To understand the impact of time horizon and discount rate on Social Security claiming strategies, let’s compare the present value of claiming benefits at age 62 versus age 70. The following table shows the present value of benefits under different real discount rates, assuming a Primary Insurance Amount (PIA) of $30,000 per year and a life expectancy of 90 years.
Real Discount Rate | Present Value at Age 62 | Present Value at Age 70 | Difference (70 – 62) |
0% | $652,500 | $831,600 | $179,100 |
2% | $491,499 | $574,949 | $83,450 |
6% | $305,791 | $292,285 | -$13,507 |
Key Takeaways from the Table
- Zero Discount Rate (0%): If you have a real discount rate of 0% — meaning you value future and present income equally (which is pretty unlikely) — delaying benefits until age 70 results in a significantly higher present value compared to claiming at age 62. In this scenario, delaying yields an increase of $179,100.
- Moderate Discount Rate (2%): With a real discount rate of 2%, the benefit of delaying to age 70 still exists, though it’s reduced to $83,450. This suggests that, even when factoring in inflation and opportunity cost, waiting can be advantageous if you live long enough.
- High Discount Rate (6%): At a high discount rate of 6%, the present value of claiming benefits at age 62 exceeds that of delaying until age 70 by $13,507. This high discount rate indicates a strong preference for immediate income, often because you expect high investment returns or have pressing financial needs. It’s important to note that a 6% discount rate is unusually high and is used here to illustrate specific circumstances in which early claiming might make sense (and even then, the benefit isn’t huge).
Practical Example: Applying This to Your Retirement Strategy
Consider this: If you are in good health and expect to live well into your 80s or 90s, delaying Social Security benefits might provide you with greater financial security. However, if you have a shorter life expectancy or believe you can earn a return greater than the growth rate of Social Security (around 8% per year for delayed retirement credits), claiming earlier may be the better choice.
For instance, if you have a real discount rate of 2%, delaying makes sense as it provides additional value without exposing you to market risks. On the other hand, a 6% real discount rate may lead you to claim early to leverage higher investment opportunities.
The Role of Guaranteed Income in Retirement
One of the key benefits of delaying Social Security is that it increases the amount of guaranteed, inflation-protected income you will receive for life. This guaranteed income can be particularly valuable for retirees who are concerned about market volatility or outliving their assets. Unlike other investments, Social Security is not subject to market risk, making it a reliable source of retirement income.
For many retirees, the peace of mind provided by higher guaranteed income may outweigh the potential benefits of taking an earlier, smaller benefit and investing it. And one of the best ways of figuring out how you value reliable income is to take the RISA® to discover your retirement income style – and what that means for your retirement income plan.
Aligning Your Claiming Strategy with Your Goals
Deciding when to claim Social Security benefits is more than a matter of choosing a date—it’s about optimizing your retirement income to align with your broader financial goals and risk tolerance. By understanding the impact of your time horizon and real discount rate, you can make an informed decision that maximizes the value of your benefits.
If you’re still uncertain about when to claim, consider using a Social Security calculator to see how different claiming ages and discount rates impact your benefits, or speak to a financial advisor who can help you weigh the trade-offs in light of your personal circumstances.
