Car Depreciation Calculator

Live purchase vs residual board with a first-year cliff peel and year ladder so early value loss does not hide inside a flat per-year average.

Educational planning sketch only. Not an appraisal, market guide quote, or IRS tax depreciation schedule. Condition, region, and demand change real resale.

Purchase price vs residual value

Depreciation is the gap between what you paid and what a planning sketch says the car might still be worth after you hold it. This page’s framing is that twin: purchase versus residual, with percent kept and dollars lost beside a year-by-year ladder.

It is not the payment vs all-in affordability job, and not the auto loan equity race (loan balance versus value). Here the schedule itself is the product.

Decision framing: “If I buy at this price and hold N years on this curve, what residual and first-year cliff should I expect in a sketch?”

Three transparent curve families

Instead of pretending a brand picker is a market guide, the board uses three published educational profiles: Typical new (~20% year one, then ~14% of remaining), Holds value (gentler), and Steep drop (larger early bite). Flip curves on the same price and years to see sensitivity without fake precision.

Real resale still depends on model, trim, condition, options, and region. Treat curves as literacy tools, then confirm with a live market quote when money moves.

First-year cliff peel

Averaging total loss by years held hides the usual new-car pattern: a large year-one drop, then smaller annual bites. The cliff peel shows year-1 loss, later-years average loss per year, and the gap between them.

Load Steep · 3 years. Compare Y1 loss to later average. Then flip to Holds · 5 years and watch the cliff shrink.

Year ladder

Each rung lists the rate applied to that year’s starting value and the ending residual as dollars and percent of original purchase. The ladder is the schedule you can sanity-check before you pair it with a loan balance elsewhere.

A soft floor at 8% of purchase keeps very long holds from modeling zero. Scrap and wholesale floors in the real world differ.

Annual miles stress

Miles around a 12k baseline leave rates alone. Higher annual miles nudge the curve up; lower miles nudge it down slightly. That factor is a directional stress peel, not an insurer’s mileage table or a tax deduction schedule.

High miles preset (18k) is the quick demo: same typical curve, harder residual.

What the panel actually computes

Positive purchase price. Whole years from 1 to 12. Declining-balance rates by curve, with a mild fade after year two and an optional miles factor.

rate_y1 = firstYear × milesFactor rate_yn = annual × milesFactor × 0.97^(n-2) // n ≥ 3 value_n = max(value_(n-1) × (1 − rate_n), 0.08 × purchase) totalLoss = purchase − residual cliffGap = year1Loss − avg(loss in years 2…N)

Where this hands off

After residual literacy, hand off for loan equity, payment budgets, leases, or insurance costs.

Loan vs value race: auto loan calculator
Payment vs all-in budget: car affordability
Lease payment sketches: car lease
Insurance cost context: car insurance

Worked scenarios

Scenario A: New · 5 years. $32k on Typical. Read residual and % kept, then open the cliff peel so year one is not buried in the five-year average.

Flip Curve family to Holds value without changing price or years. Residual rises; cliff softens. That is curve sensitivity.

Scenario B: Steep · 3 years. Higher MSRP with a steep profile. Cliff-heavy narrative is the teaching beat for early trade-ins.

Scenario C: High miles. 18k mi/year on Typical. Miles factor above 1.0 pulls the ladder down versus the 12k baseline story.

Scenario D: Holds · 5 years. Same price as A with a gentler curve. Use when you want a “keeps value” sketch before you check a market guide.

Common mistakes

Treating the ladder as a binding offer from a dealer or appraisal service.
Using average loss per year without reading the first-year cliff.
Ignoring underwater risk when a loan balance is compared only here instead of on the auto loan equity tools.
Confusing resale sketches with IRS tax depreciation (MACRS).
Assuming miles stress replaces condition, accident history, or trim demand.
Planning a trade-in from year-5 residual without a live market check.

How to use this panel

Load a scene preset or enter purchase price, years held, and annual miles.
Pick Typical, Holds value, or Steep drop.
Read purchase vs residual, kept/lost peel, first-year cliff, and the year ladder.
Share when you want URL state. Typing does not rewrite the address bar. Confirm real offers with a market guide before you sell or refinance.

When not to stop at residual sketches

Stop here for depreciation literacy. Hand off for loans, budgets, leases, or insurance.

Equity race: auto loan.
Budget ceiling: car affordability.
Lease: car lease.
Legal / finance wording: disclaimers.

Frequently asked questions

What does this car depreciation calculator estimate?

It sketches a residual value after a chosen hold period using transparent curve profiles (typical, holds value, steep). You get dollars kept, percent kept, a year ladder, and a first-year cliff peel. It is planning literacy, not an appraisal.

What is the first-year cliff peel?

New cars often lose a large share of value in year one, then smaller bites later. The peel compares year-1 loss to the average annual loss in later years so that early drop does not hide inside a single “average per year” number.

How is this different from the auto loan calculator?

Auto loan focuses on payment and the equity race between loan balance and vehicle value. This page owns the depreciation schedule itself: purchase versus residual, curve family, and the year ladder.

Are the brand curves exact market values?

No. The three profiles are educational sketches with published rates on the board. Real resale depends on model, condition, options, region, and demand. Use a market guide when you need a quote.

How do annual miles change the sketch?

Miles above a ~12k baseline nudge rates up; lower miles nudge them down slightly. That stress peel is directional, not a mileage-deduction table from an insurer or tax authority.

Is this tax depreciation (MACRS)?

No. This is consumer resale-value literacy. Business tax depreciation uses different IRS rules. Do not file taxes from this board.

What is the residual floor?

The sketch floors value at 8% of purchase so long ladders do not go to zero. Real scrap or wholesale floors differ; treat the floor as a modeling guardrail.
