# @untemps/loan-schedule
Class to generate a schedule of monthly loan payments.
It has been built with a single purpose in mind so far, but features will be added in the next fews weeks.
Don't hesitate to contact the team if you think about a specific usage we may address.
## Installation
```bash
yarn add @untemps/loan-schedule
```
## Usage
Import `LoanSchedule`:
```javascript
import { LoanSchedule } from '@untemps/loan-schedule'
```
Create an instance of `LoanSchedule` passing three objects:
```javascript
// Settings object that describes the properties of the loan (see below "Loan Settings")
const loanSettings = {
amount: 79950, // Amount of the loan in any currency
term: 25, // Loan term in years
interestRate: 2, // Interest rate in percentage
insuranceRate: 0.5, // Insurance rate in percentage
}
// List of amortizations monthly paid until the term of the loan (see below "Loan Amortizations")
const loanAmortizations = [
{
label: 'Rent', // Label of the amortization.
value: 600, // Amount of the maortization.
type: LoanScheduleAmortizationType.CREDIT, // Type of the amortization: "credit" or "debit"
},
{
label: 'Payment',
type: LoanScheduleAmortizationType.DEBIT,
compute: LoanScheduleCompute.PAYMENT, // Computation method of the amortization (optional). That means the amount has to be automatically calculated by the class. "payment" and "insurance" are available so far.
},
{
label: 'Property Tax',
value: 30,
rate: 5, // Yearly inflation rate of the amortization (optional).
type: LoanScheduleAmortizationType.DEBIT,
},
]
// Configuration of the output (see below "Configuration")
const config = {
headers: {
year: {
label: 'Année',
},
balance: {
label: 'Solde',
},
},
}
const schedule = new LoanSchedule(loanSettings, loanAmortizations, config);
```
