How Much Do You Need to Retire? - Root Financial

Determining how much you need to retire can be a complex task, but by answering two essential questions, you can gain a good understanding of your financial requirements to retire. In this post, we will explore these two questions and discuss different approaches to estimate your retirement expenses accurately.

Question 1: What are your retirement expenses?

One of the primary steps in planning for retirement is to determine your expected expenses during your retirement years. While it may be challenging to predict exact figures, there are methods to estimate your monthly expenses.

Bottom-Up Approach:

The bottom-up approach involves itemizing every expense you anticipate having during retirement. This comprehensive method helps you create a detailed view of your monthly expenses. By considering factors such as housing costs, healthcare expenses, travel, hobbies, and other day-to-day expenditures, you can build a more accurate financial picture. Although this approach can be time-consuming, it offers a precise estimation of your retirement expenses.

Top-Down Approach:

For individuals who do not closely track their monthly expenses or are unsure about the specifics, the top-down approach can provide a useful approximation. Instead of adding up your current monthly expenses, start with your monthly take-home income. Then, subtract expenses that will no longer apply during retirement, such as mortgage payments or work-related costs. Next, add in expenses that will be present during retirement but are not present today, such as increased healthcare or leisure activities. This simplified approach can provide a reasonable estimate, even if it is not as precise as the bottom-up method.

Question 2: How much of those expenses need to be covered by your portfolio?

Once you have estimated your retirement expenses, the second question to answer is how much of those expenses will be covered by your investment portfolio. This step involves assessing the income generated by your investments, including stocks, bonds, and other assets. By considering factors such as market performance and inflation, you can evaluate the sustainability of your portfolio and ensure it can support your desired lifestyle throughout retirement.


It is important to note that everyone’s retirement expenses and portfolio requirements will be unique. Even if two individuals have identical expenses of $100,000 per year, their retirement needs may differ significantly. Factors such as lifestyle choices, healthcare requirements, and personal goals can significantly influence the amount of money required for a comfortable retirement. It’s important to personalize your retirement planning based on your individual circumstances and objectives.

Planning for retirement requires a thoughtful analysis of your expected expenses and the amount needed to cover those expenses from your investment portfolio. By addressing those two key questions, you can gain a clearer understanding of your retirement needs. 

Whether you choose the bottom-up approach, which itemizes each expense, or the top-down approach, which simplifies the estimation process, the goal is to create a realistic financial plan that aligns with your desired retirement lifestyle. Remember, retirement planning is an ongoing process, and it is essential to review and adjust your plans periodically to ensure a secure and fulfilling retirement.
