Mode d'emploi
- Saisissez le montant du prêt, le taux d'intérêt annuel et la durée en années.
- Consultez la mensualité, les intérêts totaux et le paiement total dans les cartes récapitulatives.
- Utilisez le graphique et le tableau pour voir comment capital et intérêts évoluent chaque année.
FAQ
Que montre ce calculateur d'amortissement ?
Il calcule une mensualité fixe pour un prêt entièrement amortissable, puis génère un échéancier année par année répartissant chaque paiement entre capital et intérêts. Il affiche aussi le solde restant et les intérêts cumulés sur un graphique.
Que signifient les lignes du graphique ?
Solde restant (bleu, décroissant) est ce que vous devez encore. Intérêts cumulés (vert, croissant) sont les intérêts payés jusqu'à présent. Les premières années paient plus d'intérêts ; les dernières, plus de capital.
Quelle formule est utilisée ?
La mensualité utilise PMT = P × [r(1+r)^n] / [(1+r)^n − 1], où P est le montant du prêt, r est le taux mensuel et n est le nombre de mois. Chaque mois, intérêt = solde × r et capital = mensualité − intérêt.
Mes données sont-elles envoyées ?
Non. Le traitement s'effectue localement dans votre navigateur.
Cet outil fournit-il des conseils financiers ?
Non. Les résultats sont des estimations informatives uniquement et ne remplacent pas un conseil professionnel.
Introduction
Un calculateur d'amortissement vous aide à comprendre comment un prêt à taux fixe est remboursé au fil du temps : le montant de chaque mensualité, la part d'intérêts par rapport au capital, et la façon dont le solde restant tombe à zéro.
Saisissez le montant du prêt, le taux d'intérêt mensuel et la durée. L'outil calcule votre mensualité et affiche un échéancier mois par mois plus un graphique interactif.
Qu'est-ce qu'un calculateur d'amortissement ?
Le Calculateur d'amortissement utilise trois entrées :
- Montant du prêt — total emprunté
- Taux d'intérêt mensuel (%) — coût mensuel de l'emprunt
- Durée du prêt (années) — durée du remboursement
Il estime :
- Mensualité — paiement fixe chaque mois
- Intérêts totaux — tous les intérêts payés sur la durée complète
- Paiement total — capital plus intérêts totaux
Un graphique interactif et un tableau mois par mois montrent comment le remboursement se répartit entre intérêts et capital au fil du temps.
Comprendre les lignes du graphique
Le graphique affiche deux lignes qui suivent la progression du remboursement du prêt.
1. Solde restant (ligne bleue)
Ce qu'elle montre : Ce que vous devez encore à la fin de chaque année.
Pourquoi c'est important : Cette ligne descend vers zéro à mesure que le prêt est remboursé. La courbe est plus prononcée dans les dernières années, lorsque plus de chaque mensualité va au capital.
2. Intérêts cumulés (ligne verte)
Ce qu'elle montre : Total des intérêts payés depuis le début jusqu'à chaque année.
Pourquoi c'est important : Cette ligne monte tout au long du prêt. La plupart des intérêts sont payés tôt, lorsque le solde est le plus élevé — un élément clé pour comparer les coûts de prêt.
Comment la mensualité est calculée
L'outil suppose une mensualité fixe sur un prêt entièrement amortissable :
PMT = P × [r(1 + r)^n] / [(1 + r)^n − 1]
Où :
P= montant du prêtr= taux mensuel ÷ 12 (taux mensuel en décimal)n= années × 12 (nombre de mois)PMT= mensualité
Chaque mois :
- Intérêt = solde restant ×
r - Capital = mensualité − intérêt
- Nouveau solde = ancien solde − capital
Si le taux est de 0 %, la mensualité se simplifie en P / n.
Cas d'usage courants
- Estimer les mensualités pour un prêt immobilier, un crédit auto ou un prêt personnel.
- Voir le coût total des intérêts avant d'emprunter.
- Comparer comment une durée plus courte ou un taux plus bas réduit les intérêts payés.
- Enseigner comment l'amortissement passe de paiements riches en intérêts à des paiements riches en capital.
Mensualité constante vs capital constant
Tous les prêts n'utilisent pas la même structure. Cet outil utilise la mensualité constante (amortissement) : le paiement total reste fixe tandis que capital et intérêts évoluent. Avec le capital mensuel constant (trả gốc đều), le capital remboursé est fixe et le paiement total diminue.
| Mensualité constante (cet outil) | Capital mensuel constant | |
|---|---|---|
| Ce qui reste fixe | Paiement total chaque mois | Capital chaque mois |
| Ce qui change | Capital ↑, intérêts ↓ | Paiement total ↓ |
| Premiers mois | Paiement total plus bas | Paiement total plus élevé |
| Intérêts totaux (même taux et durée) | Plus élevés | Plus bas — remboursement plus rapide |
| Courant en | États-Unis, Europe, Inde, Japon, nombreux prêts immobiliers | Chine, Vietnam, certains prêts d'entreprise asiatiques |

Bonnes pratiques
- Confirmez si votre prêteur utilise les mêmes règles d'arrondi pour le paiement final.
- Les impôts, assurances et frais ne sont pas inclus sauf si vous ajustez les entrées manuellement.
- Les remboursements anticipés de capital ne sont pas modélisés — cet outil suppose uniquement des paiements fixes programmés.
- Traitez les résultats comme des estimations de planification, pas des garanties ni des conseils financiers.
