About ChargebackCost.com
An independent reference for what chargebacks actually cost merchants in May 2026. Per-processor fees, Visa VAMP and Mastercard ECM monitoring thresholds, reason-code evidence requirements, friendly-fraud breakdown, prevention ROI math. No payment-vendor relationships, no affiliate links, no quote forms.
Why this site exists
Chargeback information sits in three places, none of which serves a merchant making cost decisions. The card networks publish detailed reason-code reference manuals (Visa Core Rules, Mastercard Chargeback Guide) but those documents are written for acquirers, not merchants, and treat cost as a downstream concern. Payment processors document their own dispute systems (Stripe Disputes, PayPal Resolution Center) but each in their own framing, so cross-processor comparison takes hours of side-by-side reading. The third place is chargeback recovery vendors (Chargebacks911, Chargeflow, Justt) whose pricing pages are gated by sales contact forms before the per-dispute cost is visible.
ChargebackCost.com pulls those three layers together: the card-network reference (reason codes, monitoring thresholds, fine schedules), the processor comparison (Stripe, PayPal, Square, Shopify, Adyen, Braintree, Authorize.net, Worldpay), and the per-merchant true-cost math (bank fee plus lost product plus shipping plus labor plus dispute response time). The goal is reproducibility: every fee, threshold, and reason code on the site cites its primary source, and the calculator output should be defendable in front of a finance team.
The other gap is regulatory freshness. Visa rolled VDMP and VFMP into VAMP in April 2025, and tightened the North America excessive threshold from 1.8% to 1.5% in April 2026. Stripe launched Smart Disputes in June 2025 with a two-tier $15 + $15 fee. Mastercard ECM thresholds and TC15/TC40 settlement-code conventions continue to evolve. This site re-verifies the published positions monthly, single-sourced through one LAST_VERIFIED_DATE constant.
Who builds this
ChargebackCost.com is built and maintained by Oliver Wakefield-Smith at Digital Signet, an independent reference-content studio. The site is part of a portfolio of payment, finance, and SaaS cost-reference properties that includes churncost.com, stripecost.com, databreachcost.com, and saasvaluationmultiple.com.
The author is a payments and SaaS-economics independent. The site is not a chargeback-recovery service, not a payments consultancy lead-gen funnel, and not a fraud-tool reseller. Contact email is [email protected].
Editorial position
This is a reference site, not a reseller, not a managed-services lead-generation property, and not a consultancy funnel. Processor and vendor pages link directly to their own published documentation without affiliate or UTM tracking. The fees-by-processor comparison orders platforms by published fee size and refund-on-win policy, not by any commercial relationship.
Where a number is contested between sources (for example, the friendly-fraud share at 60% versus 75% across LexisNexis, Chargebacks911, and Juniper Research), all sources are named with their ranges shown. Where a vendor's published position is unclear or has shifted during a verification cycle (for example, the timing of Stripe's Smart Disputes pricing changes), the site flags the uncertainty rather than pick a single point estimate.
What this site covers
Editorial principles
Every fee, threshold, and reason code on this site traces back to a primary source: Visa Core Rules and the Visa Product and Service Rules, Mastercard Chargeback Guide and ECM program documents, Stripe Disputes documentation, PayPal Resolution Center docs, MRC and LexisNexis fraud-cost surveys. The source is named inline where the number is cited.
No sponsored slots, no premium positioning, no pay-to-rank. Processor order in the fees comparison is determined by published fee size and refund-on-win policy, not by any commercial relationship.
Outbound links to Stripe, PayPal, Square, Shopify, Adyen, Signifyd, Riskified, Kount, Chargebacks911, Verifi, and Ethoca are plain unaffiliated URLs. This is a reference, not a chargeback-recovery lead-generation funnel.
Processor fees, monitoring program thresholds, and reason-code references are re-verified against each source on the first business week of each month. The last verified label currently reads May 2026.
The verification date is held in one constant (LAST_VERIFIED_DATE in lib/schema.ts) imported by every page. Footer text, schema dateModified, and visible headings all read from that single source so cosmetic refreshes are not possible.
Prevention ROI math uses published per-transaction tool costs and the lower bound of vendor-claimed reduction rates. Where vendors claim 70-80% reduction we model 60%; where they claim 90% we model 70%. The calculator output is meant to defend in front of a finance team, not a vendor.
Methodology in brief
Per-processor chargeback fees come from each processor's own public pricing or disputes documentation. Monitoring program thresholds (Visa VAMP, Mastercard ECM) come from each network's published acquirer rules. Reason codes are listed from Visa Core Rules sections on dispute conditions and the Mastercard Chargeback Guide. Friendly-fraud share figures cite LexisNexis True Cost of Fraud, MRC Global Fraud Survey, and Chargebacks911 Field Reports. Per-dispute true-cost math uses a documented formula with COGS bands by category that any merchant can re-run with their own numbers.
