What Tepuy Solutions is
Tepuy Solutions is a collection of assumption-driven financial modeling tools focused on Australian personal finance decisions, particularly property vs shares, rent vs buy, and retirement feasibility.
The calculators are designed to expose economic mechanics and trade-offs rather than produce simplified recommendations. Outputs are scenario-based simulations that depend on the inputs and assumptions provided.
What problem Tepuy addresses
Many long-term decisions are evaluated using simplified calculators, rules of thumb, or narrative assumptions that obscure total cost and risk. Tepuy was created to model decisions explicitly across time by tracking cash flows, taxes, leverage effects, and opportunity cost together.
A typical use case is testing how outcomes change when assumptions change (interest rates, growth rates, rental income, costs, time horizon), rather than relying on a single projected result.
How Tepuy differs from typical calculators
- Assumptions are explicit and adjustable. Key drivers such as interest rates, growth rates, taxes, costs, and timing are visible inputs.
- Cash flow and net worth are modeled together. Tepuy aims to keep affordability and long-term outcomes in the same model, so users can see constraints as well as totals.
- No default recommendation is enforced. The goal is to make sensitivities visible (what matters, and why) rather than prescribe a single decision.
For a detailed explanation of assumptions, cash-flow mechanics, opportunity cost, and limitations, see the Tepuy Methodology.
What Tepuy is not
Tepuy is not a robo-advisor, portfolio allocator, budgeting app, or prediction engine. It does not claim to forecast markets or property prices. Its purpose is to make trade-offs visible, not to eliminate uncertainty.
Who Tepuy is for
Tepuy is primarily used by people who prefer quantitative reasoning and explicit assumptions: engineers, analysts, technically inclined professionals, and individuals comparing major long-term decisions.
It is not designed as mass-market financial guidance; it is designed as a transparent modeling layer that users can test, critique, and adjust.
Geographic and regulatory scope
Tepuy’s calculators are currently focused on Australian financial settings, including Australian tax context where relevant. Outputs are simulations for educational and decision-support purposes and do not constitute financial advice.
