How to Use IW Retirement Planner
Retirement planning is an empowering process, regardless of age. The process of planning not only fosters a sense of financial security but also a roadmap for financial well-being.
IW Retirement Planner streamlines retirement planning by bringing together two widely-used methods: straight-line forecasting, which projects future financial needs, and industry-standard Monte Carlo stress testing, which evaluates risk by simulating different market conditions. This approach combines the strengths of both techniques, offering a powerful, free tool that helps you feel confident in your plan and the decisions you make.

Spending Strategies
IW Retirement Planner supports both fixed and flexible spending options. The right choice between these approaches depends on your financial circumstances, risk tolerance, and personal preference.

Choose your Spending Strategy
- Fixed spending withdraws a set, inflation adjusted, amount each year, offering a predictable and stable income that simplifies budgeting for essentials. While this approach provides simplicity, it may not account for lifestyle changes or needs at various stages of retirement. Use one of the methods from Step 1 to estimate the income you will need to maintain a comfortable retirement. IW Retirement Planner applies a 1% annual reduction to Fixed spending expenses, based on research from The Center for Retirement Research. You can modify this reduction amount in Assumptions. Difficulty in Practice: Low
- Smile spending is an age-based approach to retirement spending, grounded in research showing that retirees often spend more in the early and late stages of retirement and less during the middle years. This method helps align spending with the evolving lifestyle and needs of a typical retiree. Use one of the methods outlined in Step 1 to estimate your initial expenses. Difficulty in Practice: Medium
- Dynamic spending provides the most flexibility by adjusting spending levels based on market performance and portfolio health. It is best suited for retirees who are willing to reduce expenses during lean market years in exchange for the ability to spend more initially and during favorable market years. This approach also helps mitigate the risk of outliving assets by adapting spending in response to changing economic conditions. Dynamic spending starts with a withdrawal of 5% of your total investment portfolio. Each subsequent year adjusts the prior year's spending for inflation and then applies 'guardrails' of 4% and 6%. If the withdrawal amount falls below 4% of the total investment portfolio, it is increased to 4%. Conversely, if the withdrawal amount exceeds 6% of the portfolio, it is capped at 6%. Difficulty in Practice: Medium
Investment Income Buckets
- Cash & Equivalents are readily available funds, including Savings, CDs, Money Market, and Treasury Bills. You can set a maximum value for this bucket using the Invest Excess Cash field. Any amount above this limit is automatically invested in Taxable Investments at year-end.
- Taxable Investments include stocks, bonds, and mutual funds held outside retirement accounts. You can specify the bond allocation and cost basis (the purchase price of investments).
- Tax-Deferred Investments are retirement accounts that allow you to defer federal income taxes until funds are withdrawn. Common examples include 401(k), 403(b), 457(b), IRA, SEP, and SIMPLE IRA accounts. You can specify the bond allocation for this bucket.
- Tax-Free Investments are retirement accounts where taxes are paid on contributions up front, so future growth and withdrawals are generally tax-free. You can specify the bond allocation for this bucket. If your 401(k), 403(b), 457(b), IRA, or SIMPLE IRA includes a Roth component, include that amount in this bucket. IncomeWize does not currently have an HSA income bucket, but HSA funds can be included in the Tax-Free Investments bucket.
Tax-Deferred Income Bucket
Non-Investment Income Buckets
- Social Security is a federal program providing monthly retirement income based on your earnings history. Enter your estimated monthly benefit at Full Retirement Age (in today’s dollars) and the intended starting date. Refer to the FAQ for guidance on getting the most accurate FRA benefits estimate on SSA.gov. If you are already receiving benefits, select the current month and enter your before-tax monthly amount. Spousal and survivor benefits are estimated automatically when applicable.
- Pensions provide a fixed monthly retirement income, typically funded by a former employer. Enter your expected benefit starting amount and the percentage payable to a surviving spouse, if applicable. For pensions with cost-of-living adjustments (COLAs), enable automatic increases and set the COLA rate in Assumptions. Those already receiving pension income should select the current month and enter the current before-tax amount. Lump sum distributions should be entered in Other Income.
- Employment covers both part-time or full-time work. Enter your expected annual income, annual raise, and employment start/end dates. Part-time work can be included to supplement retirement income or to explore early retirement options. You can also include full-time employment to reflect continued spousal work. If there is a gap between your retirement date and your spouse's, be sure to account for any employment during that period. For example, if you plan to retire in 2040 and your spouse in 2045, make sure to include your spouse's employment from 2040 to 2045.

Healthcare and Long-Term Care Expenses
Healthcare expenses are likely to be among your most significant costs in retirement. Estimating these expenses is typically divided into two phases: pre-Medicare (before age 65) and Medicare (age 65 and beyond), as each involves different planning considerations.

- Pre-Medicare Estimates
Estimated pre-Medicare expenses can also be included. For help estimating these costs, you may refer to the Kaiser Family Foundation's Health Insurance Marketplace Calculator, which accounts for subsidies, or Vanguard's Health Care Cost Estimator. - Long-Term Care Expenses
The U.S. Administration for Community Living estimates that a 65-year-old today has approximately a 70% chance of needing some form of long-term care in the future. You can add estimated long-term care costs for the final two years before longevity age. Tools like the Genworth Cost of Care Survey and Vanguard’s Health Care Cost Estimator can help forecast these expenses.

Choose from three tax optimization strategies
- Withdrawal Strategy allows you to choose which bucket to withdraw income from first, Taxable or Tax-Deferred Investments. For example, selecting Tax-Deferred Investments may be beneficial if 401(k)s and Traditional IRAs make up a large portion of your savings, as this can help reduce the tax impact of Required Minimum Distributions later in retirement.
- Roth Conversion allows you to convert Tax-Deferred Investment funds into Tax-Free Investments, up to a chosen federal income tax bracket. The ideal times to consider Roth conversions are usually during lower tax years, typically after retirement, but before starting Social Security or Required Minimum Distributions (RMDs). Converted funds are taxed as ordinary income but offer tax-free growth, help reduce the long-term tax impact of Required Minimum Distributions, and provide tax-free income later in retirement.
- Tax Minimizer attempts to lower taxes to a specified federal income tax bracket by replacing Tax-Deferred Investment withdrawals, which are taxed as ordinary income, with Tax-Free Investments, or Taxable Investments which are taxed as long-term capital gains. The goal is to replace just enough ordinary income to remain within the chosen bracket and avoid pushing income into higher tax tiers. This feature is typically most effective for those who are not at risk of large RMDs later in retirement.
Run an AI-Enabled Stress Test
Monte Carlo stress test Probability of Success score
Interpreting Your Stress Test ScoreYour financial goals and retirement lifestyle preferences play an important role in understanding your Probability of Success score. For those with modest retirement goals and flexibility in their spending, an 85% success rate can suggest a reasonably sound retirement plan. However, if you have ambitious goals or wish to maintain a higher standard of living in retirement, aiming for 90% or above provides a larger financial cushion and greater peace of mind.
