How WorthTheRepair Works

WorthTheRepair estimates current value, compares your repair quote, and explains the tradeoffs so you can choose repair or replacement with confidence.

What the calculator does

The calculator estimates today’s value for your item based on age, condition, and typical lifespan. It then compares that value to your repair quote and applies the 50% rule to recommend repair or replacement.

Estimates depreciation using category-appropriate curves.
Applies condition adjustments to reflect real-world wear.
Explains break-even time in plain language.

Inputs explained

Category, Brand, Model

These set the typical lifespan and market average used for valuation.

Age

Used to estimate how far along the depreciation curve the item is.

Condition

Adjusts the value up or down based on wear and reliability.

Original Cost & Repair Quote

The core comparison. These determine the repair-to-value ratio.

Depreciation math

Electronics typically lose value faster early on, so we use an exponential curve. Appliances tend to decline more steadily, so we use a linear curve tied to lifespan.

Electronics

Exponential curve: big early drop, flatter later.

Appliances

Linear curve: steady decline over expected lifespan.

The 50% rule

If a repair costs more than about 50% of the item’s estimated current value, replacement is usually the safer financial choice. This is a heuristic—not a rule—and should be combined with your usage needs and reliability expectations.

Break-even analysis

We estimate how long the item must last for the repair to pay for itself. This helps you reason about whether the repair “buys” enough time to make sense.

Example: If a repair costs $200 and the item’s value “burns” at $10 per month, the repair must last about 20 months to break even.

How to interpret the chart

The value line shows estimated depreciation over time.
The repair line shows your quoted cost.
The crossover point is where repair cost exceeds value.
Use the curve to see how much life is realistically left.

Limitations + disclaimers

Estimates are informational only and may not reflect your exact item condition, local labor rates, or parts availability. Always consult a qualified professional for final repair decisions.

FAQ

Is the 50% rule always correct?

No. It’s a guideline. Reliability, usage, and your budget can shift the decision.

What if I don’t know the original cost?

Use the market average helper to estimate a baseline value.

Why do electronics depreciate faster?

Rapid model cycles reduce resale value quickly, so early drops are steeper.

Can I override the replacement cost?

Yes. Enable override if you know the exact price of a comparable replacement.

Why does the recommendation change?

Small changes in age, condition, or quote can shift the break-even point.

Is this advice professional guidance?

No. WorthTheRepair provides informational estimates only.
