Build a tool to estimate car mileage costs

Here’s a simple mileage cost estimator tool concept, which can be built as a web app. This version will be interactive, allowing users to input trip distance, fuel efficiency, and fuel price to calculate total cost.

Mileage Cost Estimator Tool

Inputs:

• Trip Distance (miles): e.g., 150

• Fuel Efficiency (miles per gallon): e.g., 25

• Fuel Price per Gallon ($): e.g., 3.80

Output:

• Estimated Fuel Cost: $22.80

Example Web App Code (React with Tailwind CSS)

Let’s build a basic web app using React and Tailwind CSS:

jsx
CopyEdit
import { useState } from 'react';

export default function MileageCostEstimator() {
  const [distance, setDistance] = useState('');
  const [efficiency, setEfficiency] = useState('');
  const [price, setPrice] = useState('');
  const [cost, setCost] = useState(null);

  const calculateCost = () => {
    const d = parseFloat(distance);
    const e = parseFloat(efficiency);
    const p = parseFloat(price);

    if (!d || !e || !p || e === 0) {
      setCost('Invalid input');
      return;
    }

    const result = (d / e) * p;
    setCost(`Estimated Fuel Cost: $${result.toFixed(2)}`);
  };

  return (
    <div className="max-w-md mx-auto mt-10 p-6 bg-white rounded-2xl shadow-lg space-y-4">
      <h1 className="text-2xl font-bold text-center">Mileage Cost Estimator</h1>
      <div>
        <label className="block text-sm font-medium text-gray-700">Trip Distance (miles)</label>
        <input
          type="number"
          value={distance}
          onChange={(e) => setDistance(e.target.value)}
          className="mt-1 block w-full p-2 border rounded"
        />
      </div>
      <div>
        <label className="block text-sm font-medium text-gray-700">Fuel Efficiency (MPG)</label>
        <input
          type="number"
          value={efficiency}
          onChange={(e) => setEfficiency(e.target.value)}
          className="mt-1 block w-full p-2 border rounded"
        />
      </div>
      <div>
        <label className="block text-sm font-medium text-gray-700">Fuel Price ($/gallon)</label>
        <input
          type="number"
          value={price}
          onChange={(e) => setPrice(e.target.value)}
          className="mt-1 block w-full p-2 border rounded"
        />
      </div>
      <button
        onClick={calculateCost}
        className="w-full bg-blue-600 text-white py-2 rounded hover:bg-blue-700"
      >
        Calculate
      </button>
      {cost && <div className="text-lg font-semibold text-center text-green-600">{cost}</div>}
    </div>
  );
}

How It Works

• User inputs total distance in miles.

• User enters their vehicle’s average fuel efficiency.

• User adds the current price of fuel per gallon.

• The tool calculates the total fuel cost using the formula:

ini

Cost = (Distance / Fuel Efficiency) * Fuel Price
