Direct answer
The price per liter is not the cost per session. Add tank rental, delivery, the minimum order, surcharges, evaporation and unused inventory, then divide by completed sessions. Whether a supplier can reach you reliably, and how fast it refills, can matter as much as the price.

Calculation
Planned liters purchased = greater of (session use + losses in liters) or the contractual monthly minimum
Monthly LN2 cost = planned liters purchased x delivered liquid price + tank rental + delivery fees + surcharges + tax allowance
LN2 cost per completed session = monthly LN2 cost / completed nitrogen sessions
Take consumption for your model from a current manual or a written supplier answer. The CRYONiQ XC / XC Plus brochure, reviewed October 6, 2026, lists 5-8 liters for the pressurized system and 4-7 liters for the non-pressurized system. Keep those configurations separate when requesting session-consumption figures; confirm the measurement conditions for the exact model. Published figures for other equipment belong to their own model and operating setup.
Losses are part of the volume you buy, not a second charge added on top of liquid that's already priced. If the liquid price already includes delivery, don't add a delivery fee again. The calculator below doesn't model tank inventory, supplier scheduling or safe storage.
At zero completed sessions, cost per session is undefined even though rental and delivery charges keep coming. Keep that fixed cash exposure visible in the low-volume case.

Calculate your full nitrogen supply cost
Use a dated local gas quote and the consumption documented for your exact equipment. Every amount starts blank; enter zero only when it is confirmed.
Formula and scope
Formula version 2 / 2026-10-06. Session use = completed sessions x liters/session. Required liquid = session use + other use/losses. Planned purchase = greater of required liquid or contractual monthly minimum. Monthly cost = planned purchase x liquid price + tank rental + deliveries x delivery fee + other fees + tax allowance. Per-all-session allocation = monthly cost / all completed sessions, including unpaid. Per-paid-session allocation = the same full supply bill / delivered paid sessions, undefined at zero paid sessions. Do not compare different denominators or mistake an allocated bill for marginal session cost. This simplified nominal scenario does not model tank inventory, refill scheduling, safe storage, staff, equipment cost or profit.
The interactive calculator needs JavaScript. The formulas and supplier quote sheet below remain available for your own worksheet.
Separate paid volume from all resource-consuming cycles
The calculator counts sessions twice: all completed nitrogen sessions, including unpaid ones, and the paid subset. Trials and training use liquid without bringing in money. Keep their consumption apart from precooling and idle losses that happen outside sessions, so the same liters aren't counted twice.
You get two allocations of the same bill. Dividing by all completed sessions gives the all-session figure; dividing by paid sessions gives the paid-session figure. If paid volume is zero, the paid figure is undefined while the monthly bill remains. Neither is the marginal cost of one more session.
The worksheet prices liquid and the supply charges you enter. The nitrogen equipment's electricity is a separate input. Carry the complete gas bill and the non-overlapping electricity bill into the ROI monthly energy budget, or use the matched operating-period comparison. The download keeps the model, period, sources, units and any unknown scope.
Verify the stated range and fixed-cost exposure
Suppose a supplier quotes 5-8 liters per exposure and USD 1-2 per liter. Multiplying the endpoints gives USD 5-16 per session for liquid alone. A narrower quoted range needs specific paired assumptions behind it. This is arithmetic, not a price recommendation.
Precooling, training exposures and idle losses all use liquid without producing paid sessions. Ask whether each consumption figure is per exposure, per day or per fill; whether losses are already included; and whether the minimum is a purchase commitment or just a delivery threshold.
| Input | Low-volume month | Base month | Source needed |
|---|---|---|---|
| Completed sessions | Buyer assumption | Buyer assumption | Staffing and booking plan |
| Precooling and trial liquid | Unknown until documented | Unknown until documented | Exact-model manual or written response |
| Session consumption | Same documented model basis | Same documented model basis | Named revision and test conditions |
| Minimum, rental and deliveries | Contract terms | Contract terms | Dated local gas proposal |
| Stockout disruption | Separate cash scenario | Separate cash scenario | Refill lead time and emergency terms |
The CRYONiQ cost guide was reviewed October 6, 2026; its category examples don't replace a delivered quote. Keep a tank's unused capacity separate from the volume charged on the invoice.
Current market orientation
The public Cryo Innovations tank-options sheet, read October 6, 2026, lists tank rental separately from refill estimates. Its prices are undated illustrations with no stated delivery location, taxes or current terms, so borrow the fee categories for your quote requests rather than the amounts for your budget. The Cryomed PRO Ultra sheet separates precooling from session consumption - another figure to request for your exact model.
CRYONiQ currently gives a broad supplier price range and notes that rental and delivery may be extra. Its guide says geography, volume, delivery schedule, purity and tank arrangement all change the result. Use those figures as a prompt to get local quotes, not as a budget line.
Compare the same delivery scenario
Give every supplier the same address, equipment model, expected operating days, monthly session range and required tank system. Ask for one normal-month quote and one low-volume quote, and ask what happens under the contract when actual use misses the estimate.
Line up liquid price, rental, deposit, delivery, fuel or environmental surcharges, minimum order, unused inventory, contract term and annual price increases, with taxes recorded separately. A low per-liter price can still mean a higher monthly bill when delivery minimums or tank fees dominate.
Availability and site questions
- Does the supplier serve the exact address and intended application?
- Which tank type and connection are approved for the named equipment?
- Is a site risk assessment required before delivery?
- What access width, surface and storage conditions are required?
- What is the normal refill lead time and emergency process?
- Who inspects the tank and related components?
- What happens during holidays, weather events or allocation limits?
- Can the contract move with the business or equipment?
Scenario calculation
Run a low, base and peak month. Start from model-specific liters per session, then add expected losses and minimum deliveries. Show the monthly total, cost per completed session and the cash effect of one missed delivery. Keep consumption, price and volume editable so the numbers can be updated when local quotes change.
Supplier selection rule
Price matters, but so do reliable delivery, compatible equipment, site acceptance, transparent fees and emergency cover. Date every quote, and check the market again before renewing the contract or changing equipment.
Sources and limitations
The CRYONiQ supply guide was rechecked on October 6, 2026, and the two linked manufacturer PDFs were read separately the same day. Checking documents doesn't establish current delivered gas prices. Local supplier contracts, a safety assessment and current model documents decide the final plan.
