Income, costs, timing, and goals stay next to the projected result.
Budget

The result is tied back to spending room, targets, and goal progress.

Start assessmentYour Assessment Explained
Present bias
High
Near-term rewards may feel heavier than future benefits when tradeoffs are close.
Risk tolerance
Moderate
Upside matters, but the downside needs to be visible before a larger commitment feels usable.
Control preference
High
Editable assumptions and clear knobs can make projections easier to trust.
Complexity tolerance
Moderate
More detail helps when it is segmented into the decision, funding, and tracking layers.

View full FAQWhat is Basis Financial?
Basis Financial is a personal finance platform for modeling major decisions and connecting them to budgeting, safe-to-spend, and goal progress. It helps users see how a choice may change a financial path before they commit.
Does Basis give financial advice?
No. Basis shows projections based on visible inputs and assumptions. It does not provide financial, legal, tax, lending, insurance, or investment advice.
What models can I use?
Basis currently includes vehicle cost, rent vs. buy, career comparison, and investment strategy models. Each model is built for one decision type and shows the assumptions behind the result.
Can someone use Basis before creating an account?
Yes. Basis can start with a model or assessment before account creation. Saving a plan, connecting budget data, and tracking drift over time require an account.
How do Budgeting and Financial Plans connect?
Budgeting explains the current financial picture: accounts, transactions, recurring cashflow, and safe-to-spend. Financial Plans use that context to show goal funding and allocation tradeoffs.
What does Pro add?
Pro is intended for the more connected Basis system: richer saved history, deeper planning, budgeting, and premium model detail where available. The pricing page is the source of truth for current plan packaging.
