Comparison pages written by a vendor are usually worthless, because the vendor wins every row. These are written to be useful instead: each one has a "choose them if" section that means it, and each names the things Killion does not do — no tax modeling, no permanently free plan (there is a live no-signup demo), no shared household access.
Head to head
Killion vs ProjectionLab
Both tools simulate a whole financial life rather than answering a single retirement question. They differ most in how your data gets in, and in what the simulation is actually doing under the hood.
Killion vs Boldin
Boldin is the most complete retirement-tax modeller aimed at individuals. Killion is the deeper simulation engine. Which matters more depends on how close you are to drawing down.
Killion vs Empower Personal Dashboard
Empower’s dashboard is free because it is the front door to a wealth-management business that charges a percentage of your assets. Killion charges a flat subscription and sells nothing else.
Killion vs Monarch Money
These two products are often shortlisted together and are not really competing. Monarch is the best-in-class budgeting and shared-household tool. Killion is a simulator that also budgets.
Killion vs Kubera
Kubera is the broadest net-worth tracker available — it will hold your house, your startup equity and your wine. Killion is a simulator: fewer asset types, far more done with them.
Killion vs FI Calc
FI Calc is the free, beloved FIRE-community calculator for historical withdrawal strategies. Killion is planning software that links accounts and runs a seeded regime-switching engine. They are not substitutes; they are neighbours.
Killion vs WealthTrace
WealthTrace is the closest positional competitor we have seen: dedicated retirement planning software, linked investment accounts, Monte Carlo, what-if scenarios. The honest split is tax depth versus engine transparency.
Killion vs Quicken Simplifi
Quicken Simplifi is the everyday-money app the review roundups keep naming. Killion is a retirement simulator. They overlap on linked accounts and a future-looking view; they do not overlap on what “planning” means.
Killion vs NewRetirement (now Boldin)
NewRetirement is Boldin. The query still exists, so this page exists. The product you would actually compare is Boldin PlannerPlus versus Killion’s simulator.
Killion vs Portfolio Visualizer
Portfolio Visualizer is a backtesting and analytics lab for asset-class mixes. Killion is a household retirement simulator with read-only account linking. They overlap on the word Monte Carlo and almost nowhere else.
Killion vs Pralana
Pralana is a detailed US tax-and-projection calculator, sold as Excel Gold and as Pralana Online. Killion is a web simulator with a public methodology and no tax engine.
Killion vs MaxiFi
MaxiFi computes a sustainable living standard from lifetime resources (Kotlikoff-style consumption smoothing). Killion tests named withdrawal rules on seeded market paths. Both are retirement math. They are not the same question.
Killion vs other Monte Carlo tools
“Best” is the query. This page is a fact table. Different products mean different things by Monte Carlo — a household plan, an asset-class lab, a living-standard engine, or an Excel tax model.
Looking to switch
ProjectionLab alternatives
Most people looking for a ProjectionLab alternative want one of three things: automatic account syncing, tax modeling, or a lower price. Those point at three different products.
Boldin alternatives
Boldin covers two things at once — retirement tax planning and lifetime projection. Replacing it means deciding which half you actually used.
FI Calc alternatives
FI Calc is excellent at what it is. An alternative is worth considering when you want those withdrawal rules attached to linked holdings and a Monte Carlo that is not only historical start years.
WealthTrace alternatives
WealthTrace Standard is $229 a year. Killion Pro is $132. Price is not the reason to switch — tax modelling is the reason to stay, and a public engine is the reason to look.
Empower Personal Dashboard alternatives
Empower’s dashboard is free because it is the front door to wealth management. An alternative means either another free dashboard, or software you pay for in cash so nobody takes a percentage of the portfolio.
How to choose between them
Almost everyone shortlisting these tools is really answering one of four questions. Working out which one you have narrows the field faster than any feature matrix.
- "When can I retire?" — a simulation question. Killion or ProjectionLab.
- "Should I convert to a Roth this year?" — a tax question. Boldin.
- "Where is my money going?" — a budgeting question. Monarch.
- "What am I actually worth?" — a tracking question. Kubera, or Empower if you want it free.
If you have two of those questions, running two tools is usually cheaper and better than finding one that does both adequately. The whole category costs less per year than a single month of a 1% assets-under-management fee on a mid-sized portfolio — you can check that on the investment fee calculator.
