Planning retirement income is different from saving for retirement: it is about turning a nest egg into a reliable paycheck while managing taxes, Social Security timing, and the risk of outliving your money. The right software lets you model those decisions before you commit. Here are seven of the best retirement income planning tools for 2026 and who each serves best.

This article is educational and not financial advice. Software models are only as good as their assumptions — consider validating major decisions with a fiduciary financial planner.

1. Boldin (formerly NewRetirement) — Best Overall DIY Planner

Boldin is the most comprehensive consumer planning platform: it models Social Security timing, Roth conversions, withdrawal strategies, taxes, and "what-if" scenarios in depth. Its free tier is useful, and the paid PlannerPlus unlocks the detailed levers serious planners want. The best all-around choice for hands-on retirees.

2. MaxiFi Planner — Best for Tax-Smart Spending and Lifetime Math

Built on economics research, MaxiFi focuses on smoothing your living standard across your lifetime and optimizing Social Security and withdrawal timing. It is more rigorous (and less flashy) than most — ideal for analytically minded users who want defensible numbers.

3. Income Lab — Best for Dynamic Withdrawal Management

Income Lab specializes in ongoing income management with guardrails that adjust spending as markets move, rather than a static 4% rule. Often used by advisors, it appeals to retirees who want a living, adjustable income plan.

4. ProjectionLab — Best for Visualization and Scenario Modeling

ProjectionLab offers beautiful, interactive charts and flexible scenario building for early retirement (FIRE) and traditional planning alike. Great for users who think visually and want to stress-test multiple paths.

5. Empower Retirement Planner — Best Free Tool for Account Aggregation

Empower's free planner links your accounts to give a real-time net-worth and retirement projection with Monte Carlo analysis. The trade-off is that using it may invite a sales call, but the free modeling is genuinely useful.

6. Fidelity Retirement Tools — Best for Fidelity Customers

Fidelity's planning tools and Retirement Income Planner are robust and free to customers, integrating your held accounts with income and withdrawal modeling. A strong default if your assets already sit at Fidelity.

7. Social Security Administration Calculators — Best Free Starting Point

The SSA's official estimators help you see how claiming age changes your benefit — the single highest-impact retirement income decision for many households. Free, authoritative, and the right first stop before layering on other tools.

How to Choose the Right Tool

Match the tool to your complexity. If you just want to nail Social Security timing, start free with the SSA estimators and Empower. If you want to model Roth conversions, tax brackets, and withdrawal sequencing, Boldin or MaxiFi earn their subscription. Whatever you use, test conservative assumptions for returns, inflation, and longevity — optimistic inputs produce dangerously rosy plans. Use Monte Carlo or guardrail features to understand the range of outcomes, not just the average.

The Bottom Line

Boldin is the best comprehensive DIY planner, MaxiFi the most rigorous on tax and lifetime math, and Empower plus the SSA calculators the best free starting points. Begin with the free tools, graduate to a paid planner if your situation is complex, and consider a fiduciary's review before locking in irreversible decisions.
