Grading Service Cost Calculator

This calculator totals up the real, all-in cost of submitting a batch of items to a professional grading service and compares it against the value you expect grading to add. It looks up a per-item fee and turnaround time from a five-tier table modeled on typical PSA/NGC/PCGS pricing — Value/Economy ($22, ~65 days) through Walkthrough ($400, ~2 days) — multiplies by your item count, then adds a flat round-trip shipping cost plus a shipping-insurance charge computed as a rate per $1,000 of declared value, doubled to cover both legs of the trip. On the benefit side, you supply an expected graded-value multiplier (how many times the raw value you think a graded copy will fetch), and the calculator works out the value uplift per item, subtracts your true all-in cost per item, and reports the resulting net profit — both per item and across the whole batch — along with an ROI percentage on the grading spend itself.

It also computes a break-even multiplier: the minimum graded-to-raw value ratio your items need to hit just to cover costs, which is useful for deciding whether a submission is worth the risk before you commit. The core assumption baked in is that you already have a realistic sense of what grade your items will receive and what that grade typically sells for — this tool does the cost math, not the grading prediction, so garbage-in expected-multiplier assumptions will produce a confidently wrong profit estimate. Higher service tiers cost more per item but free up capital and reduce market-timing risk from long waits.
