# Symulator kredytu hipotecznego
|
||||
|
||||
Nowoczesna aplikacja one-page do symulacji kredytu hipotecznego: zmienne stopy w czasie, nadpłaty, raty równe/malejące, skrócenie okresu albo obniżenie raty, wykresy, CSV/PDF, WebSocket live.
|
||||
|
||||
## Start
|
||||
|
||||
```bash
|
||||
docker compose up --build
|
||||
```
|
||||
|
||||
Otwórz:
|
||||
|
||||
```text
|
||||
http://localhost:8080
|
||||
```
|
||||
|
||||
## Funkcje
|
||||
|
||||
- symulacja rat równych i malejących,
|
||||
- harmonogram zmiennego oprocentowania w konkretnych miesiącach,
|
||||
- nadpłaty jednorazowe i cykliczne,
|
||||
- tryb nadpłaty: skrócenie okresu albo zmniejszenie raty,
|
||||
- live przeliczenia przez WebSocket,
|
||||
- wykresy liniowe, słupkowe i kołowe,
|
||||
- opis oszczędności: odsetki, czas, suma nadpłat,
|
||||
- eksport CSV i PDF,
|
||||
- pobieranie aktualnej stopy referencyjnej NBP z oficjalnej strony jako pomocnicza wartość bazowa.
|
||||
|
||||
## Uwaga
|
||||
|
||||
To symulator edukacyjny. Wynik może różnić się od harmonogramu banku, bo banki stosują własne zasady zaokrągleń, dat płatności, prowizji i aktualizacji WIBOR/WIRON.
