A calculator can explain one account while missing what funding it takes away from another part of the strategy.
Financial strategy simulation
See how one financial decision changes your whole system.
Build a strategy from income, debts, accounts, investments, and expenses. Change an assumption or reroute a cash flow, then explore how that decision affects every connected part over time.
Free to use. No linked accounts. Explore ideas without changing your real finances.

Why model the whole system
A financial strategy is more than its biggest account.
A final balance does not show where the cash came from, what it passed through, or which assumption drove the result.
Compounding happens across the system: income funds assets, assets generate income, and one redirected flow changes what grows next.
Put the moving parts on one canvas so you can test the relationship between them, not just calculate them in isolation.
How it works
Build it. Change it. Watch the rest respond.
Start with what exists
Add the income, accounts, investments, debts, expenses, and optional advanced positions that belong in the strategy you want to explore.
Route every meaningful dollar
Connect the pieces with percentages or monthly amounts. The arrows make priorities, dependencies, and reinvestment loops visible.
Simulate the whole strategy
Explore assumed-rate projections, uncertainty ranges, and supported historical replay. Then change one input and compare the response.
Useful, not falsely certain
Explore the result without mistaking it for a prediction.
Assumptions stay visible
Rates, contributions, yield, volatility, and flows stay visible so you can identify what is driving the result.
Risk has a place in the result
Monte Carlo ranges show a spread of possible outcomes instead of presenting one projected line as a promise.
History is context, not a forecast
Supported historical replay shows how the same strategy would have behaved over a measured window. It does not predict the next one.
Who it is for
Built for people who want to test possibilities.
A good fit
- Exploring how debt payoff, saving, and investing interact
- Testing a retirement, income, portfolio, or financial flywheel strategy
- Comparing different ways to route the same monthly cash
- Visualizing when internally generated income begins doing more of the work
- Adding selected advanced crypto positions to a broader financial model
Not a fit
- Looking for stock picks, trading signals, or personalized recommendations
- Expecting the simulator to choose the right strategy for you
- Using it as a day-to-day budget or account-tracking service
- Treating an estimate or historical replay as a guaranteed outcome
FAQ
The important questions, answered plainly.
Is this financial advice?
No. You supply the assumptions and the Lab shows how that system behaves under its stated model. It does not recommend specific investments, transactions, or actions.
Do I need to connect a bank or brokerage account?
No. The Lab is browser-based. You enter only the values you want to model, including hypothetical scenarios you do not yet own.
What is this tool meant to help me do?
It helps you visualize and test financial strategies. Build the system you want to explore, change one assumption or flow, and observe how the connected results change. It does not decide which strategy you should use.
How is this different from a spreadsheet?
A spreadsheet gives you cells and formulas. Compound Strategy Lab gives you positions and flows, so you can see how money moves and re-simulate the connected system after each change.
Can I use historical data?
Eligible holding nodes can use bundled market series for historical replay. The replay preserves the window's observed sequence; it is evidence about that period, not a prediction of the next one.
What does it cost?
It is free to use. The goal is to make credible system-level planning accessible before you need a larger financial-planning stack.
Start with a question
Test the strategy you have in mind.
Start with a template or a blank canvas. Build the connections, change the assumptions, and explore how the system compounds.
