About
Mission and methodology
We built World Mortgage Calculator to provide clear, global-friendly mortgage estimates with transparent assumptions, accessible design, and responsible disclosures.
What we solve
Mortgage shopping is confusing. Rates vary by country and compounding rules differ. We unify the basics: property price, down payment, APR, and term, then show monthly payments and total interest with clear assumptions.
How the calculator works
- Applies a fixed-rate amortization formula with your selected compounding frequency.
- Updates in real time as you type with aria-live announcements for accessibility.
- Formats results using your chosen currency without storing your inputs.
Data and assumptions
- No taxes, insurance, HOA fees, or PMI included.
- No currency conversion; we assume the currency you select is the loan currency.
- Payments are on time with no prepayment penalties considered.
Why trust us
We avoid dark patterns, keep ads unobtrusive, and provide disclosure blocks directly next to results. Inputs stay on your device and any analytics are anonymized with consent.
