All guidesFrequently asked questions
Is the Personal Loan Calculator free?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.
Does anything I enter leave my computer?
No. The Personal Loan Calculator runs entirely in your browser using JavaScript. Because the work happens locally, the page also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What is the Personal Loan Calculator used for?
The jobs it is built for: comparing offers where one has a lower rate but a higher fee. Understanding the true cost of a consolidation loan. Budgeting for a fixed monthly repayment. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
How precise is the result?
The calculation runs in double precision and the result is shown to ten significant figures, so converting a value and converting it back returns the original. What is displayed is rounded for readability; what is copied is not.
