Demurrage, detention and storage tariffs are set by each carrier, terminal and contract and change frequently. The preloaded figures are editable industry-typical examples, not quotes — always verify against the current published tariff or your service contract before paying or disputing an invoice.
Rail demurrage exists to keep CPKC's equipment cycling — the 2023 Canadian Pacific–Kansas City Southern merger — the first single-line network linking Canada, the US and Mexico, and every railcar dwelling at a dock is capacity someone else ordered. The charge structure is simple (free days, then escalating day rates) and this tool prices any version of it.
About CPKC Demurrage Calculator
Operationally: Single-line Mexico service means demurrage can accrue in three jurisdictions on one move — and Mexican terminal practices differ substantially from US/Canadian norms. That distinction decides whether a charge is your cost or your dispute — keep placement records, service requests and gate timestamps as a matter of routine, not just when an invoice looks wrong. Enter your held time, free allowance and the tariff's rates. The per-tier breakdown mirrors the carrier's billing line; recompute every statement, because rail demurrage ledgers net credits and debits monthly and errors compound quietly across a fleet.

Frequently asked questions
How is CPKC demurrage calculated?+
Held time minus free days, priced per day per railcar. With the defaults (1 free, then $75 for 2d, $150 after), 5 days held = 2 × $75 + 2 × $150 = $450 per railcar — multiply by your fleet size for the statement-level number.
Does CPKC demurrage work the same in Mexico?+
Mechanically similar (free time, then daily charges) but governed by Mexican terminal and railroad practices, often with different free-time conventions and currency. On a three-country single-line move, check which segment generated the charge — the invoice should identify the serving territory, and each has its own dispute path.
Does free time differ by commodity or car type?+
Almost always — tank cars, autoracks and specialised equipment carry different free time and rates than boxcars, and bulk commodities often have their own provisions. The tariff's car-type table is the authoritative source; using the generic rate for specialised equipment is a common audit miss in both directions.
Do demurrage credits offset debits at CPKC?+
Depends on the road's current tariff — traditional credit/debit offsetting has been curtailed across the industry since 2018, which is exactly what shipper groups contested at the STB. Read the credit rules in the current document rather than assuming last contract's netting still applies.
