Glossary
- Fixed Payment (Standard Amortization)
- A repayment method where the monthly payment remains constant. A higher portion goes to interest early on.
- Fixed Principal
- A method where the principal payment is constant. Monthly payments start high and decrease over time, resulting in less total interest.
- Prepayment
- Making extra payments towards the loan principal. This reduces the total interest paid and shortens the loan term.
- DTI Ratio (Debt-to-Income)
- The percentage of your gross annual income that goes towards paying your debts. Lenders often look for generic DTI under 36%.
- Total Interest
- The overall cost of borrowing the money, paid over the entire duration of the loan.
FAQ
- Q.Quel est le meilleur moment pour effectuer des remboursements anticipés ?
- Plus vous effectuez des versements supplémentaires tôt pendant la durée du prêt, plus vous économiserez d’argent sur les intérêts à long terme.
- Q.Puis-je simuler des prêts hypothécaires à taux variable ?
- Cet outil simule actuellement des prêts à taux fixe. Pour les ARM (hypothèques à taux variable), la saisie du taux moyen attendu fournit une estimation approximative.
- Q.Mes données financières sont-elles chargées sur un navigateur ?
- Non. Cet outil fonctionne entièrement dans votre navigateur en utilisant JavaScript. Aucune donnée n'est envoyée sur Internet.
- Q.Cela prend-il en compte l'assurance habitation ou les taxes foncières ?
- Non, ce calculateur ne gère que les composantes principal et intérêts (P&I) du prêt. Les prêts hypothécaires du monde réel peuvent avoir des exigences mensuelles plus élevées en raison des taxes, des assurances ou des frais HOA.
