FIManager vs ProjectionLab (2026)

What each tool is

ProjectionLab is a financial planning simulator built for the financial independence (FI) community. You model your financial life — income, spending, milestones, retirement scenarios — and it runs Monte Carlo simulations and historical backtesting to estimate your chance of success. It's deliberately not connected to your bank accounts: its homepage says "No link to your accounts," and its help docs confirm direct account linking isn't supported (third-party plugins for Lunch Money, YNAB, and Monarch exist instead). It's a well-regarded, bootstrapped product with a genuinely good free sandbox for exploring.

FIManager is a DIY financial planning app for people working toward financial independence. Same core idea — build a plan, run Monte Carlo simulations, see your projected FI date and chance of success — with three different design choices: your accounts can sync automatically via Plaid (or stay fully manual, your call), an AI assistant ("Ask AI") helps you build, stress-test, and understand your plan, and every assumption behind every number is visible and editable. No hidden assumptions is the core promise. It also has a couples mode: one shared portal, two logins, no shared passwords.

One thing we won't pretend: ProjectionLab has been at this since 2021 and has earned its reputation. FIManager is early. This page is about which trade-offs fit you.

Where ProjectionLab is genuinely strong

We'd rather you trust this page than click a CTA, so here's the honest list:

• Simulation polish. ProjectionLab's Monte Carlo and historical backtesting are mature and thoughtfully presented. Its cash-flow Sankey diagrams are some of the nicest visualizations in the category.
• Tax scenario features. Its Premium tier covers Roth conversions, ACA subsidy modeling, capital gains harvesting, and withdrawal strategies. FIManager doesn't match that tax-scenario depth today, and we're not going to pretend otherwise.
• Onboarding without commitment. Its sandbox mode drops you into a pre-populated example persona in about a minute — a genuinely good way to explore before entering your own data.
• Community trust. It's a bootstrapped product with years of steady development and a loyal following in the FIRE community. That trust was earned.
• International support. Multi-currency and country-specific tax presets, which matter if you're planning outside the US.
• Privacy by design. Not linking to your accounts is a feature for some people. If you never want a planning tool near your bank credentials, ProjectionLab's stance is a legitimate plus (FIManager's Plaid sync is optional for exactly this reason — manual mode is first-class).

Where FIManager takes a different path

• An AI assistant that works on your plan. ProjectionLab doesn't advertise any AI features as of July 2026. FIManager's Ask AI helps you set up scenarios, explains why your chance of success moved when you changed something, and turns a long form-filling session into a conversation. If you've ever stared at a planning tool wondering which of 30 inputs actually matters, this is for you.
• Your real numbers, automatically. ProjectionLab's docs are upfront that direct account linking isn't supported (it's on their public roadmap; third-party plugins partially bridge the gap). In practice that means a manual update ritual to keep your plan current. FIManager syncs balances via Plaid so your plan tracks reality without the ritual — and if you'd rather not link anything, manual entry works fully.
• Show-your-work math. Every FIManager projection exposes its assumptions — returns, volatility, inflation, iteration count — and lets you edit them. When the math is visible, you can check it, challenge it, and actually trust it. That's the "no hidden assumptions" promise, and it's aimed squarely at spreadsheet people who never trusted black-box planners.
• Monthly billing. ProjectionLab's paid tiers are annual-only ($129/yr Premium). FIManager bills monthly or yearly — try it for a month, leave whenever. We think planning tools should earn your renewal, not assume it.
• Built for couples. One shared portal, two separate logins, joint and individual accounts — no password sharing.

And the honest flip side: FIManager is new. Smaller feature surface, shorter track record, fewer years of edge-case polish. If that's a dealbreaker, ProjectionLab is the safer pick today — genuinely.

Pricing compared

Prices verified on projectionlab.com/pricing, July 4, 2026. Check their page for current figures.

ProjectionLab (annual billing only):

• Basic — free. Forecasting, financial planning, Monte Carlo simulations, historical backtesting.
• Premium — $129/year. Adds cash-flow projections, tax optimization, withdrawal strategies, Roth conversions, ACA subsidies, capital gains harvesting, compare mode, downloadable reports, and more.
• Pro — $549/year. Advisor features: client management, dashboard, 10 client seats.

FIManager:

• Free — start planning, projections, and see how the tool thinks. The FI calculator is free with no signup at all.
• Basic and Premium — monthly or yearly billing via Stripe. Current prices are on fimanager.app — we'd rather point you at the live page than let this one go stale.

The structural difference matters more than the digits: with ProjectionLab you commit to a year; with FIManager you can pay month to month and cancel anytime.

Which should you choose?

Choose ProjectionLab if:

• You enjoy detailed manual modeling and want the most mature simulation feature set available today
• You need Roth conversion, ACA subsidy, or capital-gains-harvesting scenarios now
• You explicitly don't want a tool connected to your accounts
• You plan outside the US and need country-specific tax presets

Choose FIManager if:

• You want your plan connected to your real account balances (Plaid), not a monthly copy-paste ritual
• You want an AI assistant to build and explain the plan instead of doing everything by hand
• You want to see and edit every assumption behind every number
• You're planning as a couple and want one plan with two logins
• You prefer monthly billing over an annual commitment
• You're happy backing a newer product early, knowing the feature surface is smaller today

Or do the obvious thing: ProjectionLab's Basic tier is free and FIManager has a free tier plus a no-signup calculator. Try both with your own numbers. The right tool is the one you'll actually keep updated.

Frequently asked questions

Is there a ProjectionLab alternative with bank sync?

Yes. ProjectionLab doesn't support direct account linking (its help docs say so; third-party plugins for Lunch Money, YNAB, and Monarch exist). FIManager connects to your accounts via Plaid so balances stay current automatically — and manual entry remains fully supported if you'd rather not link anything.

Does ProjectionLab have an AI assistant?

Not as of July 2026 — no AI features are advertised on its site. FIManager includes Ask AI, an assistant that helps you build scenarios and explains what's driving your projections.

Does ProjectionLab have a monthly plan?

No — its paid tiers (Premium $129/yr, Pro $549/yr) are billed annually, per its pricing page in July 2026. FIManager offers monthly or yearly billing.

Is ProjectionLab worth $129 a year?

For hands-on planners who want mature simulations and deep tax scenarios, honestly, it can be — it's a polished tool with a real track record. If you'd rather have live account data, an AI assistant, and monthly billing, that's the trade FIManager makes instead.

Is FIManager free?

There's a free tier, and the FI calculator requires no signup at all. Paid tiers (Basic, Premium) bill monthly or yearly.

Can I trust a comparison page written by a competitor?

Only if it shows its work — same as a financial projection. Every ProjectionLab claim here was verified against their live pages on July 4, 2026, and sourced at the bottom of this page. If anything is out of date, tell us and we'll correct it.
