Questions and answers

Are the currency rates up to date?

Yes. The currency converter uses the official rates of the European Central Bank, the Bank of Israel and the Bank of Russia, refreshed several times a day. The source and date show next to the result.

Can I rely on the result to take a loan?

The result is an estimate for planning only. The exact terms, fees and interest are set by the bank or lender.

Is the data I enter saved?

No. The math runs in your browser; nothing is sent to the server or saved.
