Does changing currency perform a live conversion?

No. Currency selection changes number formatting, symbols and example defaults. It does not fetch exchange rates or convert existing inputs.

Are the results investment or lending advice?

No. Results are scenarios based on your inputs and simplified formulas, not lender quotes, tax calculations, investment recommendations or guaranteed future returns.

Q: Are my financial inputs stored on a server?

Core calculations run in the browser, and the site does not operate an application database for the values entered into the calculators. Hosting and advertising providers may process ordinary technical data.

01 / COMPOUND

Compound growth with monthly contributions.

A historical starting assumption is not a guarantee. Inflation, tax, sequence risk, allocation and longevity can materially change outcomes.

SCOPE

What FinSmart does—and does not do.

Five display formats

USD, EUR, GBP, JPY and KRW change symbols, formatting and defaults. No exchange-rate conversion occurs.

Browser calculations

The site has no application account or financial-input database. Hosting and advertising providers may process ordinary connection data.

General formulas

Institution-specific fees, day counts, rounding, taxes and product rules may differ from these scenarios.

FAQ

Before you rely on a result.

How do I change the currency display?

Use the display selector in the site header. It changes formatting and example defaults, not exchange rates or the economic value of existing inputs.

Are my financial inputs stored on a server?

The site does not operate an application account or database for calculator inputs. Hosting and advertising providers may still process ordinary technical data.

Are results lender quotes or investment advice?

No. They are simplified mathematical scenarios based on the values you enter.

INTERPRETATION

Keep the missing variables visible.

Currency performance is separate

When modelling foreign assets, separate investment performance from exchange-rate movement, spreads, transfer charges and taxes.

Withdrawal rates are assumptions

A 4% rate is a widely discussed historical starting point based on particular datasets and time horizons—not a universal safe rate.

Rates are not promises

A fixed rate makes scenarios comparable, but real returns and borrowing costs change over time.

Verify institution rules

Real loan payments can differ because of fees, compounding conventions, payment dates and rounding.
