About Loanquill

Loanquill is a free library of loan and interest calculators. Every page runs the standard textbook formulas — amortized payments, compound growth, annuity solving — and shows the formula it uses, so results can be checked independently.

The site is static: no accounts, no tracking pixels beyond what the privacy policy describes, and no stored personal data.
