How to Create a Profit & Loss Calculator in JavaScript

1. First of all, load the Bootstrap CSS by adding the following CDN link into the head tag of your HTML document.

<link rel='stylesheet' href='https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css'>

2. Copy the following HTML code into your webpage where you want to display the calculator.

<div class="container-fluid">
  <div class="row">
    <div class="col-md"></div>
    <div class="col col-md-6">

      <div class="spacer-0">
        <h1 class="text-success">Profit & Loss Visual Calculator</h1>

        <div class="spacer-2">
          <div class="form-group">
            <label>Amount of sales ($)</label>
            <input id="input-sales" type="number" 
                   class="form-control" required />
          </div>
          <div class="form-group">
            <label>Amount of expenses ($)</label>
            <input id="input-losses" type="number" 
                   class="form-control" required />
          </div>

          <div id="profit-n-loss-result" 
               class="alert alert-primary d-none"></div>

          <button id="calculator-profit-n-loss"
                  class="btn btn-warning">
            Calculate</button>

          <!-- Not functional in codepen --->
          <!--
          <button id="refresh-calculator"
                  class="btn btn-danger text-white float-right">
            Refresh</button>
          -->
        </div>
      </div>
    </div>
    <div class="col-md greyed"></div>
  </div>
</div>

3. The CSS code is there to style the calculator’s elements. Ensure the following CSS is included in your HTML or in a linked stylesheet.

.greyed {
    background-color: #f8f9fa;
}

.spacer-0 {
    margin: 2rem 0;
}

.spacer-2 {
    margin: 3.2rem 0;
}

4. Finally, copy the following JavaScript code into a <script> tag within your HTML file or link an external JavaScript file.

// Profit & Loss Calculator
var calculator = document
    .getElementById('calculator-profit-n-loss')
    .addEventListener('click', profit_N_loss);

var refresh_calculator = document
    .getElementById('refresh-calculator')
    .addEventListener('click', refresh_calc);

function refresh_calc() {
    location.reload();
}

function profit_N_loss(income_raw, loss_raw) {
    var income_raw = document.getElementById('input-sales').value;
    var loss_raw = document.getElementById('input-losses').value;

    income = parseInt(income_raw);
    loss = parseInt(loss_raw);
    var value = income - loss;

    var result_div = document.getElementById('profit-n-loss-result');
    result_div.classList.remove('d-none');
    if (value > 0) {
        result_div.innerHTML = 'Your profit is $ ' + value;
    } else {
        result_div.innerHTML = 'Your loss is $ ' + value;
    }
}
