About this tool
Estimate a laptop's resale price from purchase price, age, condition, battery health and remaining warranty.
A laptop resale value estimator projects what a used machine is worth today by applying declining-balance depreciation to its original price, then adjusting for condition, battery health, accessories, paperwork and remaining warranty. The model uses the pattern consumer electronics actually follow: a steep first year of roughly 35-40% loss, then about 20-25% a year after that. It reports a private-sale point estimate, a realistic asking range and the lower figure a trade-in programme is likely to offer.

Enter "Original purchase price (INR)" and "Age (months, 0-240)", then choose a Condition grade from "Like new — no marks, all accessories" down to "Faulty — sold for spares or repair".
Add "Battery health (%)", "Transferable warranty left (months)" and any "Known repair cost to deduct (INR)", and tick "Original charger included", "Original invoice and box available" and "Still receives operating-system and security updates" where they apply.
Read "Estimated private-sale value" with its ask-between range and the "Trade-in / buy-back offer to expect" row, scan the "What each factor did to the price" table, then press "Copy result" or Reset.
Separates the steep first-year drop from the slower decline afterwards, instead of one flat rate.
Applies a straight-line discount that starts easing in at 90% battery health and reaches its maximum 18% deduction at 50%, not a single cutoff.
Shows both numbers, so a low buy-back offer is easy to recognise.
Typically 35-40% of its purchase price. Depreciation is steepest immediately after purchase because the model is still on sale new, and it flattens to roughly 20-25% a year after the first twelve months.
Yes, and it eases in gradually rather than at one cutoff. Value stays full down to 90% health, then the discount grows steadily as health falls, reaching its maximum 18% deduction at 50% health and below. (Some makers, Apple included, flag a battery for service around 80% capacity — that is a real service milestone, but it is not where this estimator's pricing curve does anything special; the discount is a smooth line the whole way from 90% to 50%.)
Keep them if you can. The invoice is what lets a buyer transfer remaining warranty and prove the machine is not stolen, and listings with full paperwork consistently close faster and a few percent higher than identical ones without.
Because the buy-back company has to test, refurbish, warranty and resell the machine, so it works on a margin. Expect a trade-in or exchange offer around 70-75% of what a patient private sale would fetch. Treat both figures here as informational estimates, not quotes.
