ProjectionLab alternative: how to choose a retirement planner in 2026

Why people look for a ProjectionLab alternative

ProjectionLab is one of the better-known retirement and financial independence planners. It is detailed, flexible, and well liked by people who enjoy building models. So why do people search for an alternative?

Usually it comes down to fit rather than quality. Some people want a tool that starts from their live net worth instead of a model they build by hand. Some want a simpler setup. Some are weighing a subscription against how often they will actually use the advanced features. This guide walks through what ProjectionLab offers, where the trade-offs may be, and a practical way to decide.

It is not a takedown. If ProjectionLab fits how you think, it may be the right tool. The goal is to help you compare on the things that actually change your answer.

What ProjectionLab offers, based on its pricing page

According to ProjectionLab's published pricing page at the time of writing, there are three plans:

Two things stand out. First, the free tier is generous on core simulation. Monte Carlo and historical backtesting are listed under Basic. Second, the features many retirees care about most, such as withdrawal strategies, Roth conversions, and tax-aware modeling, are listed under Premium. Features and prices change, so confirm the current details on ProjectionLab's site before you decide.

The real cost of a planning subscription

Paying $129 per year is not a lot in absolute terms. It works out to about $10.75 per month, or roughly $1,290 over ten years and $2,580 over twenty. Whether that is good value depends on what you get for it.

A useful test is to ask what a single planning mistake could cost. If a tool helps you avoid a poorly timed withdrawal or a missed Roth conversion window, a subscription can pay for itself. If you open the tool twice a year and mostly look at one chart, the free tier of almost any planner may be enough.

A fair way to compare tools is to count how many of these you will use at least quarterly:

1. Live balances that update on their own
2. A projection that starts from your actual net worth
3. Scenario comparison (retire at 60 versus 65)
4. Tax-aware withdrawals
5. Reports you can share with a spouse or professional

If you would use only one or two, a lighter tool may serve you better. If you would use all five, a fuller planner may justify its price.

Model-first versus net-worth-first tools

This is the biggest difference between planners, and it matters more than any feature checklist.

Model-first tools ask you to define your plan: accounts, income streams, expenses, and events. You get a lot of control, and the quality of the output depends on how carefully you enter things. They suit people who like tuning assumptions.

Net-worth-first tools begin with where you are today, your assets and debts, and project forward from there. The projection stays connected to your real numbers, so it can change as your balances change. They suit people who want a living picture rather than a one-time model.

Neither is better in every case. A model-first tool may give you more precise control over a complex plan. A net-worth-first tool may keep your plan from going stale, which is a common problem: a plan built in January can be out of date by June if you never update the inputs.

A hypothetical: how much do assumptions matter more than features?

Before choosing a tool, try a baseline you can compute by hand. Suppose you are 45 with $400,000 invested, contribute $1,500 per month ($18,000 per year), and want to retire at 62, which is 17 years away. Assume a 5% annual return after inflation, a conservative planning assumption rather than a prediction.

The starting balance grows to about $400,000 x 1.05^17, or roughly $917,000. The contributions, compounded at the same rate, add about $18,000 x ((1.05^17 - 1) / 0.05), or roughly $465,000. The total is about $1.38 million in today's dollars.

A 4% initial withdrawal on that figure would be about $55,000 per year before taxes and Social Security. The 4% guideline is a rule of thumb from historical research, not a guarantee. Our article on the 4% rule covers its limits.

Now drop the return to 3%. The starting balance grows to roughly $661,000, contributions add about $392,000, and the total is about $1.05 million. A 4% withdrawal falls to about $42,000. One assumption moved the result by roughly $13,000 per year, which is more than the difference between most tools' feature lists.

The lesson is that a tool should make assumptions visible and easy to change. A clean interface that hides the return assumption is less useful than a plain one that shows it.

Where a simulation helps and where it can mislead

Monte Carlo simulations run many possible market paths and report how often a plan survives. They can be a useful reality check because real returns arrive in an uneven order, and early losses hurt more near retirement. This is often called sequence of returns risk.

Still, a success rate is only as good as its inputs. A 90% success rate built on optimistic returns and low spending may be less reassuring than an 80% rate built on cautious ones. Treat the percentage as a signal to investigate, not a score to chase. It can help to run the same plan through two tools and see whether the conclusions broadly agree.

What to check in any ProjectionLab alternative

Whichever tool you consider, these questions are worth answering:

• Does it start from my real net worth? Including real estate, business equity, and debts, not just a brokerage balance.
• Can I see every assumption? Returns, inflation, taxes, and Social Security timing should be visible.
• What is free and what is paid? Check which retirement features sit behind a paywall.
• Does it handle my situation? Business owners, pension holders, and early retirees each have particular needs.
• How much setup does it take? A tool you abandon after an hour of data entry does not help.
• Does it try to sell me something? Some free tools are built to introduce you to advisory services, which suits some people and not others.

Where Mogul Bay fits

Mogul Bay is built around connecting your current net worth to long-term projections, so your forecast starts from the numbers you already track. You can read more on the retirement planning and financial forecasting pages. If you are still comparing options, our best retirement calculator roundup and Boldin alternatives guide cover other tools side by side.

Many people end up using more than one planner at different stages. It is reasonable to run a second tool as a cross-check, especially before a major decision like retiring or selling a business.

Run your own numbers

The most useful comparison is to enter the same inputs into two or three tools and see which one explains its answer most clearly. Use a conservative return, a realistic spending figure, and a retirement age you are genuinely considering.

Create a free Mogul Bay account and run your own projection. Then change one assumption at a time and watch what moves.

Key takeaways

ProjectionLab is a capable planner, and its free tier covers core simulation, while tax-aware features are listed under its $129 per year Premium plan. Choosing between planners mostly comes down to whether you want a model you build or a projection that starts from your live net worth. Whatever you pick, favor visible assumptions, test a lower-return case, and verify current pricing with each provider.
