About CalcRight
Free, accurate financial calculators built for real home buyers — not lead-generation forms.
What We Build
CalcRight is a free financial calculator platform built for home buyers, borrowers, and anyone trying to make smarter decisions about real estate and debt. We cover three housing markets — the United States, Canada, and Australia — because mortgage rules, tax obligations, and government programs differ significantly between countries, and most calculators ignore that complexity.
Our tools include mortgage calculators, affordability estimators, refinance break-even calculators, rent-vs-buy comparisons, closing cost estimators, VA loan calculators, HELOC payment calculators, and more — over 25 specialized tools in total, all free with no account required.
Why We Built This
Most free mortgage calculators online are generic — they ignore property taxes, PMI, local closing cost rules, or country-specific regulations like Canada's CMHC mortgage insurance requirements or Australia's Lenders Mortgage Insurance (LMI) tiers. When buying a home, generic estimates can leave you thousands of dollars short on closing day.
CalcRight was built to fill that gap: accurate, locally-aware calculations that reflect where you actually live, without requiring an account or surrendering your financial data to a third party.
Who Builds This
Ilia Idelman — Founder
CalcRight was built by a software engineer who spent too long staring at oversimplified mortgage calculators that ignored property taxes, PMI thresholds, and country-specific rules like Canada's CMHC stress test and Australia's APRA serviceability buffer. The goal was simple: build tools that reflect how mortgages actually work where you live, not just a generic amortization formula.

Our Methodology
All CalcRight calculations run entirely in your browser using standard financial formulas.
Mortgage Payment Formula
M = P × [r(1+r)^n] / [(1+r)^n − 1]
where P = principal, r = monthly interest rate (annual ÷ 12), n = number of payments
Rate Data Sources
- United States: Federal Reserve FRED API — 30-year and 15-year fixed-rate mortgage averages, Federal Funds Rate, Prime Rate. Supplemented by Freddie Mac's Primary Mortgage Market Survey (PMMS).
- Canada: Bank of Canada Valet API — overnight rate, prime rate, 5-year fixed benchmark.
- Australia: Reserve Bank of Australia Statistical Table F6 — cash rate target, standard variable rate, new loan rates.
Rate data is refreshed daily via these official central bank sources and displayed with attribution timestamps on every calculator.
Country-Specific Rules
- Canada: CMHC mortgage insurance premiums are calculated per published CMHC tables. OSFI qualifying rate (stress test) applied at the greater of contract rate + 2% or 5.25%.
- Australia: LMI estimates follow standard lender tiers for LTV above 80%. APRA 3% serviceability buffer applied to affordability estimates.
- Closing costs: Calculated from state/province-specific transfer tax schedules, title insurance industry averages, and regulatory fee schedules.
