Electricity Cost Calculator

The electricity cost calculator allows consumers to estimate their annual electricity cost in a straightforward way.

Device power usage (watts): Usage hours per day: Electricity rate (dollars per kWh): Calculate cost // Get a reference to the form and result element const form = document.querySelector('form'); const resultElement = document.querySelector('#result'); // Add an event listener to the form to handle the submit event form.addEventListener('submit', event => { // Prevent the default form submission behavior event.preventDefault(); // Get the values of the input fields const watts = form.elements.watts.value; const hours = form.elements.hours.value; const rate = form.elements.rate.value; // Calculate the cost of electricity using the function const cost = calculateElectricityCost(watts, hours, rate); // Update the result element to display the cost resultElement.textContent = `Cost: $${cost.toFixed(2)}`; });
