About this calculator
Failed parts under manufacturer warranty should be returned for credit, but core returns and warranty claims get missed constantly in a busy shop — parts sit in a bin, paperwork deadlines pass, and credits that should hit your parts account never show up, quietly inflating your parts cost of goods. This calculator compares the dollar value of parts eligible for warranty return against what's actually been recovered to compute a recovery rate and the monthly dollar leak, which is worth tracking the same way you'd track any other receivable, since unclaimed warranty credit is functionally free money a vendor owes you.

FAQ
What recovery rate should a well-run parts department hit?
85%+ is a reasonable target for a shop with a dedicated warranty return process — a labeled bin system, a return deadline tracker, and a person accountable for submitting claims weekly rather than whenever there's spare time at the counter.
Why do warranty returns get missed so often?
Most vendors have a return window (often 30-90 days) and specific paperwork or failure-analysis requirements. Without a system, parts sit in a core bin past the deadline, or the paperwork gets lost between the tech who diagnosed the failure and whoever handles vendor returns.
Is it worth assigning one person to own this process?
Yes, even part-time. If unrecovered credit runs $1,000+/month, that's $12,000+/year of pure margin recovery for what's usually a few hours a week of organized tracking — a strong return on the labor invested.
Does this apply to labor warranty claims too?
Yes, in shops that do warranty repair work for manufacturers or extended service contract providers — track submitted labor claims against paid claims the same way, since those also have submission deadlines and documentation requirements that get missed under time pressure.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
