Is my financial data secure?

Yes. Unlike other financial tools, RamenTask processes all calculations locally. We do not see or store your loan amount, interest, or any other details.

What is an amortization schedule?

It is a table that shows each monthly payment over the life of the loan, broken down into the amount applied to the principal and the amount applied to interest.

Does this include property tax?

Yes, you can optionally include annual property tax and insurance costs to see a more accurate total monthly payment.

Can I use this tool offline?

Yes, once the page is loaded, the calculator works entirely without an internet connection.

Are the results accurate?

Our calculator uses standard mortgage formulas used by banks worldwide. However, you should always verify final numbers with your lender.
