Our interactive retirement calculator offers free, registered, and registered+subscribed access. So, here is a summary of what each user offers.
Guest users: Based on your input, this calculator will forecast a current or future retiree’s (and their spouse or domestic partner’s) portfolio sustainability using the Common Rule for account drawdowns. Consequently, our software provides either expected portfolio longevity or inheritance based on your inputs.
Registered users: By registering with us, you can save profile data to expedite future calculations. Interested? If so, you can register for free here.
Registered + Subscribed users: For this option, you will also have the ability to identify an improved retirement income strategy that uses either a Modified Common Rule or an Optimal Rule for account drawdowns. The table below summarizes the features for each of these options.
What questions can this calculator help to answer?
With this application, you will be able to answer fundamental questions about your retirement.
- How long will my portfolio support my annual after-tax retirement income needs, such as discretionary and non-discretionary expenses?
- If I have sufficient or excessive retirement funds, how much will my heir or favorite charitable organization receive?
- What will my future tax liabilities look like, such as from income and capital gains?

What other features can this application provide?
The calculator provides a significant amount of information to consider when planning for retirement income.
- Identifies a withdrawal plan that differs from the Common Rule to optimize your heir’s inheritance, such as when tax-deferred accounts should be used earlier.
- Uses current tax brackets for either single or married filing jointly, including the possibility of a surviving spouse.
- Supports increasing or decreasing taxes in the future, such as at the expiration of the TCJA after 2025.
- Reports potential bequest to an heir in current year dollars.
- Provides an option for your heir(s) to value the stretch provision in their inherited IRA, based on the SECURE Act, signed into law in late 2019.
- Reinvests excess retirement income due to Required Minimum Distributions (RMDs).
- Calculates taxation for both ordinary income and capital gains.
- Imposes RMD requirements consistent with your age and the SECURE Act, so that either age 70.5 or 72 applies.
- Provides options for starting balances on tax-deferred accounts (e.g. IRA, 401(k)) and tax-exempt accounts (e.g. Roth IRAs)
- Provides options to delay social security benefits and pension benefits.

My Published Research on Tax-Efficient Retirement
Over the last 10 years, I’ve published several articles on tax-efficient retirement income strategies. So, please contact us if you would like a personal copy of any of these articles.
Optimal Strategies for Traditional versus Roth IRA/401(k) Consumption During Retirement (with D. Ostrov) We establish an algorithm that produces an optimal strategy for retirees to withdraw funds between their tax-deferred accounts (TDAs), like traditional IRA/401(k) accounts, and their Roth IRA/401(k) accounts, in the context of a financial model based on Amer- ican tax law. This optimal strategy follows a geometrically simple, intuitive approach that can be used to maximize the size of a retiree’s bequest to an heir or, alternatively, to maximize a retiree’s portfolio longevity. We give examples where retirees following the approach currently implemented by major investment firms, like Fidelity and Van- guard, will reduce their bequests by approximately 10% or lose 18 months of portfolio longevity compared to our optimal approach. Further, our strategy and algorithm can be extended to many cases where the retiree has additional, known yearly sources of money, such as income from part-time work, taxable investment accounts, and Social Se- curity.DiLellio-and-Ostrov2017-Optimal-Strategies-Dec-Sci
Toward constructing tax efficient withdrawal strategies for retirees with traditional 401(k)/IRAs, Roth 401(k)/IRAs, and taxable accounts (with D. Ostrov) We construct an algorithm for U.S. retirees that computes individualized tax efficient annual withdrawals from tax-deferred, tax-exempt, and taxable accounts. Our algorithm applies a new approach using informa- tion from all years that generates an individualized strategy, in contrast to most previous approaches that chronologically generate a suboptimal strategy. Results equal or improve the chronological “naıve” withdrawal strategies advocated by many financial institutions, as well as the chronological “informed” strategies advanced by academics. Our approach allows us to determine the optimal switching times between tax-exempt and taxable account consumption, as well as between tax-deferred and taxable account consumption. It also allows us to understand the significant impact of an heir’s tax and withdrawal rate on a retiree’s optimal withdrawal strategy. Our model, which can work to optimize either portfolio longevity or the bequest to an heir, accommodates many salient tax code features, including dividends, different taxable lots, and required minimum distributions.DiLellio-and-Ostrov-2020-Toward-constructing-tax-efficient-withdrawal-strategies-FSR
The SECURE Act and your retirement objectives (with M. Kinsman) On December 20, 2019, the SECURE (Setting Every Community Up for Retirement Enhancement) Act became law after broad bi-partisan Congressional support. SECURE changed many aspects of retirement accounts, benefitting some areas and harming others. Among the benefits are an expansion of the ability to contribute to IRAs and an increase in the age at which the first Required Minimum Distribution (RMD) must be taken. On the other side of the coin, the law shortens the timeframe for heirs to take distributions from their inherited Individual Retirement Accounts (IRAs). This article summarizes how prescriptive analytics techniques are used in practice by retirees to maximize retirement portfolio longevity. The authors then contribute to this applied research by assessing how the SECURE Act affects the value of a retiree’s bequest.
