Scope
What FinanceBase provides
FinanceBase exists to turn common financial questions into calculations you can inspect. Each interactive tool is paired with its formula, timing assumptions, examples and exclusions. Current economic observations identify the producing agency, series, unit and observation date. The calculators are free to use and do not require an account.
A calculator can organize assumptions, but it cannot know your complete tax return, risk tolerance, cash-flow needs or legal obligations. Results are educational scenarios for further investigation—not personalized financial, investment, tax or legal advice.
Site operator
The site operator does not publish a personal identity. FinanceBase is listed as the publisher. Send questions and correction reports to [email protected].
FinanceBase does not claim professional credentials. Check important tax or investment decisions against current official guidance or a qualified adviser.
Publishing rules
Publishing rules
Show calculations
Calculator pages state the formula and explain contribution timing, rounding and edge cases such as a zero return.
Prefer primary sources
Tax figures link to the IRS. Current macro observations come directly from the Treasury, New York Fed and BLS. Federal Reserve releases link back to the Board.
Label dates
An observation date describes the underlying value. A retrieval or review date describes when the site checked it. Those dates are not treated as interchangeable.
Keep the last valid data
A dated, validated snapshot is included in the page HTML. If a later data request fails, that snapshot remains visible instead of becoming an empty or fabricated result.
Label estimates
Compound, DCA and FIRE results use constant assumptions. Technical-indicator labels describe entered readings and do not predict a return.
List exclusions
Known exclusions sit beside the result. FinanceBase does not publish equity or cryptocurrency quotes until a suitable redistribution-licensed source is configured.

Corrections and feedback
Financial data and tax guidance can be revised, and software can contain errors. If a value, formula, date, link or explanation appears wrong, report the page, the disputed statement and a primary source through the contact page. A correction should change the affected content and its last-updated date; it should not be hidden behind a client-only update.
For decisions with legal, tax or material financial consequences, verify the result with current official guidance and an appropriately qualified professional who can consider your circumstances.
