Cashmycell’s Phone Depreciation Calculator gives you a simple way to answer a question that often gets overlooked when buying a phone: how much will it be worth when you are ready to sell it?
Powered by more than 44,000 data points across smartphone brands and models, the tool uses historical pricing, current resale values, and market trends to estimate what your phone is worth today and how its value could change over the next 30 days, 6 months, and 1 year.
Smartphones can lose a significant portion of their value as they age, particularly around new model launches and changes in market demand. Understanding that depreciation can help you make smarter decisions about when to buy, upgrade, or sell.

When is the best time to sell your phone?
There is no single perfect time to sell a phone. However, selling sooner rather than later generally gives you a better chance of holding on to more of its value, as smartphones tend to lose value as newer models enter the market.
Timing your sale around new phone launches, trade-in offers, and major shopping or festive sales can also make a difference. If a new model is about to launch, for instance, selling your current phone before the announcement can help you avoid the drop in resale value that often follows.
Cashmycell’s Depreciation tool lets you compare your phone’s current value with its potential future value, giving you a clearer idea of whether waiting could affect your return. For example, the iPhone 15 is estimated at $331 today but could fall to $293 in a year, meaning waiting could cost you around $38 in resale value.
Why price depreciation intelligence matters more than ever
The price you pay for a smartphone is only one part of its overall cost. How much value it retains over time can also affect the true cost of ownership.
Two phones that cost roughly the same when new can have very different resale values after a few years. Factors such as brand, model, condition, storage, software support, and market demand can all affect how much value a phone retains.
Hence, understanding these factors and considering both the original price and potential resale value, you can compare models more effectively and plan your next upgrade with greater confidence.

FAQs
1. How does the Cashmycell depreciation calculator work?
Powered by Cashmycell’s Price Depreciation Intelligence, the calculator uses factors such as launch price, current resale value, historical pricing trends, and market movements to estimate how much value your phone has lost. It also projects its resale value for the next 30 days, 6 months, and 1 year.
2. How much value does a phone lose each year?
The amount varies by phone, but smartphones typically lose a significant portion of their value in the first year and continue to depreciate over time. Factors such as brand, model, condition, demand, and new releases can all affect the rate of depreciation.
3. When should I sell my phone to get the most money?
Generally, selling sooner can help you retain more of your phone’s value. It may also make sense to sell before a new model launches, as the arrival of a newer generation can affect the resale value of older models. Cashmycell’s calculator can help you compare your phone’s estimated value now with its projected future value.
4. Does my phone’s condition affect its resale value?
Yes. Scratches, screen damage, battery health, internal damage, and overall functionality can affect how much your phone is worth compared with a similar device in better condition.
5. Do iPhones depreciate slower than Android phones?
iPhones often retain their resale value better than many Android phones, but depreciation varies by model. Factors such as demand, condition, storage capacity, and the release of newer models can influence how quickly a particular phone loses value.
