Solid Credit

Solid Credit is an advanced tool designed for the precise generation of loan amortization tables. This library encompasses a variety of loan structures, including the French, German, and American systems, in addition to offering options for grace periods.

Installation

To install the library, run the following command:

npm i solid-credit

Use

To use the library, you must import the Solid class and create an instance of it, which takes as parameters the loan amount, the interest rate, the loan term, and the installment type.

Fixed Payment

import { Solid } from 'solid-credit'
// structure : (plazo, InteresAnual, Preteamo)
const data2 = Solid.fixedPayment(12, 40, 1000);// return array

Variable Payment

import { Solid } from 'solid-credit'
// structure : (plazo, InteresAnual, Preteamo)
// whith basepoint or warrning pais
const data = Solid.variablePayment( 12, 15, 1000, let basepoint = 300)// return array
// Normal
// structure : (plazo, InteresAnual, Preteamo)
const data = Solid.variablePayment(12, 15, 1000)// return array

grace period

// Grace period
import { Solid } from 'solid-credit'
// structure : (plazo, InteresAnual, Preteamo)
const data = Solid.gracePeriod(12, 15, 1000, 3);// return array

// Grace period with fixed payment
import { Solid } from 'solid-credit'
// structure : (plazo, InteresAnual, Preteamo)
const data = Solid.graceFixedPayment( 12, 15, 1000, 3) // return Promise<array>

American method

import { Solid } from 'solid-credit'
// structure : (plazo, InteresAnual, Preteamo)
const data = Solid.americanMethod(12, 15, 1000)// return array

Structure of Array

// Structure of array
[
    {
        month: 1,
        payment: 0,
        interest: 0,
        Principal: 0,
        balance: 0
    }
]

from {solid_crt} import SolidCrt

const data = SolidCrt.fixedPayment(plazo = 12, 15, 1000);

const tbody = document.querySelector('#paymentsTable tbody');

const rows = data.map(item => {
    return `<tr>
            <td>${item.month}</td>
            <td>${item.payment.toFixed(2)}</td>
            <td>${item.interest.toFixed(2)}</td>
            <td>${item.principal.toFixed(2)}</td>
            <td>${item.balance.toFixed(2)}</td>
        </tr>´
}).join('');
tbody.innerHTML = rows;
