What people use today vs. what they could use.

If you're serious about your financial future, you've probably tried these. Here's why none of them quite work.

The usual options

  • Toy retirement calculators — give one number based on one assumption. Hide the variance entirely.
  • Excel spreadsheet from a Reddit post — works, but you spend more time fixing formulas than thinking. Lost when you switch computers.
  • Bank apps — show your balances, never project the future.
  • Budgeting apps (Mint, YNAB, Monarch) — track spending, don't model retirement. Different problem.
  • "Just hire a financial advisor" — €1,000+ per session. Most retail clients don't need this; they need a model they can iterate.

What Lifecast does instead

  • 1,000-path Monte Carlo — see your real success rate, not a fake-precise single number.
  • Tax-advantaged accounts modeled — see exactly how much PPR / 401k / Roth / ISA save you in lifetime taxes.
  • FI level tracking — Lean FI, Coast FI, FI, Fat FI thresholds with progress bars. Speak the FIRE community's language.
  • Weekly progress snapshots — every week, see exactly how your plan changed. Your wealth grows visible to you.
  • Scenario comparison + Time Machine — "what if I retire 5 years earlier?" answered in real time.

Built like a finance model. Used like an app.

Every feature exists because people genuinely use it. Nothing's fluff, nothing's a gimmick. The whole thing was built by someone with a finance master's, not a generic "app builder".

Monte Carlo stress test

1,000-path simulation with configurable return volatility. See your real success probability, not the false certainty of a single average return.

Global by default

12 currencies, 7 languages. Tax examples cover EU, US, UK, AU, CA, JP. Most retirement planners are US-only — we're not.

Watch your wealth grow, week by week.

Every visit, Lifecast saves a snapshot of your plan. Come back in a week and you'll see exactly how much your projected net worth grew, how your FI age moved, and how your savings rate evolved.

Build a streak. Hit milestones. See your financial picture sharpen with every adjustment. This is what makes the difference between thinking about your future and actually building it.

Why pay for Lifecast?

The honest comparison. We're not the cheapest, we're not the most polished. We're the most useful for serious long-term planning at the price.

One subscription, decades of compound value.

A single plan adjustment per year — say, finding €500 of tax savings — pays for the subscription multiple times over. The lifetime tier is for people who want to plan once and own forever.

💡 Real ROI: A typical PPR/401k contributor sees €8,000+ in lifetime tax savings shown in Lifecast. That alone pays for 80+ years of subscription.

Frequently asked questions

Why a subscription instead of a one-time price?

Because your financial plan isn't static. New features ship monthly. Tax rules change. Your situation changes. The subscription means you always have the up-to-date tool, not a fossilized version. If you prefer one-time, the Lifetime tier is exactly that.

What's the actual long-term value?

Three concrete things. (1) Tax savings made visible: typical user sees €8k+ in lifetime tax savings from tax-advantaged accounts. (2) Better timing decisions: seeing that retiring 2 years later doubles your safety margin can be the difference between fragility and confidence. (3) Compound habit: the weekly snapshot mechanic is what turns "I should plan my retirement" into "I'm actively building my future."

Is my financial data sent anywhere?

The free version runs entirely in your browser. Your inputs live in your browser's local storage and never leave your device. The Pro tier with cloud sync (coming) will be opt-in and end-to-end encrypted.

Why should I trust the math?

The projection logic is fully visible in the year-by-year detail table — every cell has a clear derivation. Monte Carlo uses standard normal-distribution returns; we're transparent about assumptions. Built by a finance master's grad. We publish the methodology for anyone who wants the formulas.

Is this financial advice?

No. Lifecast is a modeling tool, not advice. It helps you understand the consequences of your assumptions. Talk to a licensed advisor for actual decisions, especially around taxes and complex situations in your country.

I don't live in the US or Portugal — does it work?

Yes. The math is currency-agnostic. We support 12 currencies and 7 languages. Tax-aware account examples cover the main types in EU countries, US, UK, AU, CA, JP, CH. The state pension input works for any country's system. We're built global from day one.

How is this different from Mint or Monarch Money?

Different problem. Mint and Monarch are budgeting apps — they categorize your spending. Lifecast is a planning app — it projects your wealth 30+ years out and tells you whether you'll have enough. Both can be useful; they don't overlap.

What if I cancel?

Your data is exportable any time. If you cancel Pro, you keep all the free features and your saved scenarios stay accessible. We don't hold your data hostage.
