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.

Investment Income Buckets

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.

Includes stocks, bonds, and mutual funds held outside retirement accounts. You can specify the bond allocation and cost basis (the purchase price of investments).

Retirement accounts that allow you to defer federal income taxes until funds are withdrawn.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-Deferred Income Bucket Tax-Deferred Income Bucket

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.

Funds held within a Health Savings Account that can be used for qualified medical expenses. Investment growth in an HSA is tax-deferred, and withdrawals for eligible healthcare costs are tax-free. You can specify the bond allocation for this bucket to reflect how HSA assets are invested over time.

The retirement planner prioritizes HSA funds for medical expenses but will use them for general expenses if no other funds are available.

Cash & Equivalents and Taxable Investment buckets are shared between spouses, if applicable. Review the return assumptions for your investment buckets. Equity growth rate, dividend yield, and bond yield can be customized in Assumptions.

Non-Investment Income Buckets

A federal program providing monthly retirement income based on your earnings history. Enter your estimated monthly pre-tax 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. Spousal and survivor benefits are estimated automatically when applicable.

If you are already receiving Social Security benefits, enter your current before-tax benefit amount and the date your benefits began.

Social Security Income Bucket Social Security Income Bucket

IncomeWize does not currently support custom spousal-benefit start dates for spouses with no work credits. The planner automatically starts spousal benefits at the earliest eligible date. See the FAQ Spousal Benefits section for details.

Provide a fixed monthly retirement income, typically funded by a former employer. Enter your expected pre-tax benefit starting amount and the percentage payable to a surviving spouse, if applicable. For pensions with cost-of-living adjustments (COLAs), enable automatic increases by setting the COLA rate in Assumptions. Lump sum distributions should be entered in Other Income.

If you are already receiving pension benefits, enter your current before-tax benefit amount and select Already Receiving for the starting date.

Includes recurring, non-earned income such as rental income, royalties, partnership (K-1) income, and non-qualified dividends. Enter your expected monthly pre-tax benefit, the ending date (or select Lifetime), and the percentage payable to a surviving spouse, if applicable. If your income increases annually, you can adjust the growth rate under Assumptions. All passive income is taxed as ordinary income.

If you are already receiving passive income, enter your current before-tax income amount and select Already Receiving for the starting date.

Post-retirement work, either part-time or during a staggered retirement gap.

Employment buckets cover only the years from your retirement date onward — for couples, the earlier of the two. Earnings before then aren't entered as income; instead, enter what you expect to save each year in Extra Savings.

Part-time Employment

Part-time work can be included to supplement retirement income or to explore early retirement options. Enter your expected annual pre-tax income, annual raise, and employment starting and ending dates.

If you or your spouse are already retired and working part time, enter the current annual income and select Already Employed for the starting date.

Gap Employment

A gap arises when you and your spouse retire in different years. The planner offers to add an Employment bucket for the income the still-working spouse earns during that period, and it updates automatically if either retirement date changes.

Extra Savings

Income bucket savings automatically grow each year during your pre-retirement phase. You can also boost your savings by selecting the Extra Savings option to make additional contributions. Enter the after-tax amount you plan to set aside.

Extra Expenses

In addition to your regular monthly expenses, you may have other one-time or recurring needs, such as paying off debt, taking a family vacation, or contributing to a child’s education or wedding. To include these, click the Extra Expenses button and enter any additional post-retirement expenses into your plan. Do not include Healthcare-related expenses in this section. Please use the Healthcare Costs estimator to account for medical expenses.

Other Income

Beyond your income buckets, you can include one-time or recurring income events such as an inheritance, lump-sum pension distributions, or royalties. To add these, click the Other Income button and enter both pre- and post-retirement income amounts. The values should reflect after-tax amounts and are not adjusted for inflation.
