Canadian mortgage assumptions & sources
Fixed-rate calculations use semiannual compounding. Variable-rate calculations use the compounding convention you select. Renewal term and full amortization are separate; the rate after renewal is a scenario you enter. Accelerated biweekly means half the monthly payment every two weeks.
The purchase-price down-payment minimum is 5% up to CA$500,000, then 10% on the portion above that, or 20% for a price of CA$1.5 million or more. This is not an approval test. Enter a quoted insurance premium; taxes on premiums and transfer taxes belong in upfront costs.

Repayment and tracker products load the 5% deposit basis supported by the permanent 91–95% LTV Mortgage Guarantee Scheme; lender participation and eligibility still apply. Interest-only loads a clearly labeled 25% planning amount because lenders set their own LTV and repayment-strategy requirements.
Enter the fixed-deal or rate-reset period separately from the full mortgage term. Interest-only leaves a lump sum to repay at the end. Council tax or domestic rates, insurance, service charges, purchase tax and legal fees stay as separate quoted inputs.

Australian home-loan assumptions & sources
Principal-and-interest products load the 5% minimum for eligible buyers under the Australian Government 5% Deposit Scheme. Interest-only loads a 20% planning amount and is not presented as scheme eligibility. Lenders can require more, and LMI may apply outside the scheme.
Interest is estimated from actual elapsed days with a 365-day divisor. A constant 100% offset reduces the interest-bearing balance on eligible variable or interest-only scenarios. Use quotes for LMI, council rates, stamp duty and fees.

Indian home-loan assumptions & sources
The deposit starts at 10%, 20% or 25% using RBI LTV bands and the entered purchase price as a planning proxy. The lender’s sanctioned amount and valuation determine the actual band; stamp duty and registration are outside the financed property value.
EMI is estimated on a monthly reducing balance. Floating-rate mode models one rate change and can compare changing EMI with changing remaining tenure. State taxes, fees and insurance stay as entered quotes.

France home financing
Loan styles, buyer support and calculator limits
Fixed-rate amortizing mortgages dominate. Borrower insurance is a major separate cost, and debt-service constraints affect qualification. Notary and transfer costs must be budgeted outside the advertised property price.
Government or structured support
- Prêt à taux zéro can finance part of a qualifying first main-home purchase; it is not a complete zero-interest mortgage
- PAS targets qualifying lower-income households
- Energy-renovation assistance and local support may apply separately
What to verify locally
- Combine assisted and market-rate tranches separately
- Include borrower insurance as a distinct recurring cost
- Do not infer PTZ eligibility from country alone
