Car Depreciation Calculator

Estimate the current resale value of your vehicle based on its age and depreciation rate.

function calculateDepreciation() { var price = parseFloat(document.getElementById('purchasePrice').value); var age = parseFloat(document.getElementById('vehicleAge').value); var rate = parseFloat(document.getElementById('annualDepreciation').value); if (isNaN(price) || isNaN(age) || isNaN(rate) || price < 0 || age < 0) { alert("Please enter valid positive numbers for all fields."); return; } // Formula: Current Value = P * (1 – r)^n var decimalRate = rate / 100; var currentValue = price * Math.pow((1 – decimalRate), age); var totalLost = price – currentValue; var totalPercent = (totalLost / price) * 100; document.getElementById('resCurrentValue').innerText = "$" + currentValue.toLocaleString(undefined, {minimumFractionDigits: 2, maximumFractionDigits: 2}); document.getElementById('resTotalLost').innerText = "$" + totalLost.toLocaleString(undefined, {minimumFractionDigits: 2, maximumFractionDigits: 2}); document.getElementById('resTotalPercent').innerText = totalPercent.toFixed(1) + "%"; document.getElementById('depreciation-result').style.display = 'block'; }

How Does Car Depreciation Work?

Car depreciation is the difference between the amount you paid for your vehicle and its current market value. Most motor vehicles lose value over time due to wear and tear, mileage, and the release of newer models. Understanding this financial metric is crucial for car owners looking to trade in, sell, or manage their personal finances.

The most dramatic drop in value typically occurs the moment you drive a new car off the lot—often cited as a 10% to 20% loss instantly. By the end of the first year, a car can lose up to 30% of its initial MSRP.

The Depreciation Formula Used

Our calculator uses the "Declining Balance" method, which is the most realistic way to model vehicle value loss. The formula is:

V = P × (1 – R)^n

• V: Current Value of the car.
• P: Original Purchase Price.
• R: Annual Depreciation Rate (as a decimal).
• n: Age of the vehicle in years.

Realistic Example:

If you purchase a $40,000 SUV and it depreciates at an average rate of 15% per year, after 3 years, the calculation would be:

$40,000 × (1 – 0.15)³ = $24,565

In this scenario, you have lost $15,435 in value over 36 months.

Factors That Influence Your Car's Resale Value

While the 15% annual rate is a standard average, several factors can accelerate or slow down the loss of value:

• Brand Reputation: Brands known for reliability (like Toyota or Honda) tend to hold their value significantly better than luxury brands with high maintenance costs.
• Mileage: The average driver covers 12,000 to 15,000 miles per year. Exceeding this will lower your car's value faster.
• Condition: Mechanical health and exterior/interior cleanliness play a massive role during a professional appraisal.
• Fuel Efficiency: As gas prices fluctuate, fuel-efficient vehicles or hybrids often maintain higher resale values compared to gas-guzzling alternatives.
• Market Demand: Seasonal changes or trends (like the shift toward SUVs) affect how much buyers are willing to pay for your specific model.

How to Minimize Depreciation

While you cannot stop depreciation entirely, you can mitigate its effects by:

1. Buying Used: Purchasing a 2-3 year old vehicle lets the first owner take the biggest "hit" on value loss.
2. Regular Maintenance: Keeping a meticulous service log proves to future buyers that the car was well-cared for.
3. Choosing Popular Colors: Neutral colors like white, black, and silver are easier to resell than "loud" colors like lime green or bright orange.
4. Limiting Customization: Aftermarket modifications rarely add value and often decrease the pool of potential buyers.
