Free Investment Tools, Calculators & Simulators

Investment Education, Research & Tools for Smarter Decisions.

Swoopr's free investment tools help you test assumptions, understand formulas, compare choices, and investigate market or portfolio questions without turning a calculator result into a recommendation. Every tool connects to the canonical concept it implements, the assumptions it uses, and the guide that explains when the output is useful. The library includes research tools, stock and fund screeners, risk and position-sizing calculators, retirement and portfolio tools, market visualizations, rule and reference tools, and educational simulators. Each tool states what it calculates, which inputs matter, where any external data comes from, and the limitations that can change the result.

Key Takeaways

How Swoopr Tools Should Be Read

A tool can make a financial concept easier to explore, but precision in the interface does not guarantee certainty in the result. There are four broad kinds of output in the Swoopr tool library.

Deterministic calculations

These apply a published formula to the inputs you provide. Examples include percentage changes, position-size math, fee calculations, and other arithmetic relationships. The formula can be exact while the assumptions you enter remain uncertain.

Market-data calculations

These combine a formula with external market or reference data. The result depends on the provider, field definition, adjustment policy, coverage, and data timestamp. The tool identifies whether the data is real-time, delayed, end-of-day, or otherwise limited whenever that distinction matters.

Scenario models

These let you explore what happens if assumptions change. A retirement projection, sequence-of-returns simulation, valuation model, or compounding scenario is not a prediction. It is a structured "what if?" calculation.

Screening and scoring systems

These organize a large research universe by defined criteria. A screen can help you find candidates. A score can summarize selected inputs. Neither proves that the highest-ranked security is the best investment.

Choose a Tool by the Question You Have

"How much could this cost me over time?"

Start with fee, tax, inflation, compounding, or opportunity-cost tools.

"How much risk am I taking?"

Use position-sizing, drawdown, diversification, volatility, sequence-risk, or scenario tools.

"How do these investments differ?"

Use comparison tools, then read the assumptions behind the comparison.

"What companies or funds meet these conditions?"

Use a screener as the beginning of research, then open filings, fund documents, and the Research Workbench.

"What does this market signal mean?"

Use the visualization or indicator tool alongside the relevant educational guide. Do not use a single signal as a stand-alone prediction.

"What rule or limit applies?"

Use a Swoopr reference tool, then follow the link to the regulator or government source that governs the rule.
