Interrail or Eurail against ordinary tickets — with the reservation fees and travel-day arithmetic that decide it, and that most comparisons quietly omit.
Prefilled with an indicative figure and meant to be overwritten — pass prices reset every year, so put in the price you are actually being quoted. The traveller and class discounts apply on top of whatever you enter.

The fares you entered, with seats already included in each.
Break-even: you need €343–€353 of point-to-point fares before this pass pays for itself. That works out at €86–€88 per travel day.
Enter the fare you would pay without a pass, and pick the service so the reservation fee is counted.
Several journeys on the same date count as one travel day — that is what a flexi pass actually sells. Journeys left undated are counted as a separate day each, which is the cautious reading.
Tiers with enough travel days and a long enough validity window, cheapest first.

Enter your journeys
Add each leg with its date and the fare you would pay without a pass — check one real operator site for those figures.
Pick the service for each leg
This is what pulls in the compulsory reservation fee, which is the cost that decides most of these comparisons.
Choose a pass and enter its real price
The prefilled figure is indicative; pass prices reset annually, so use the price you are being quoted.
Set the traveller type
The youth discount is 25% and is often what flips the answer.
Read the break-even
It tells you how much point-to-point fare the trip needs before the pass pays for itself.
The usual method is to add up the tickets you would have bought and compare that with the pass price. It omits the three things that actually decide the answer.
The first is reservation fees. A pass does not get you on to a TGV, an AVE, a Frecciarossa, a Eurostar or any night train — each sells a compulsory supplement on top, from a separate pass quota. Three TGV legs already add enough to reshape the comparison, and a Eurostar crossing alone can add €30–46.
The second is travel-day accounting. A flexi pass sells days, not journeys. Four trains in one day cost one day; the same four trains spread across a week cost four, and possibly a more expensive tier. Clustering journeys is the most effective way to stretch a pass, and a night train departing after 19:00 uses only its departure day while still carrying you into the next morning.
The third is operators that refuse passes outright. Italo and OUIGO are outside the system, so a pass holder pays the whole fare. This calculator puts those fares on the pass side, because counting them as covered would overstate the pass by an entire ticket.
The result is a geography, not a rule of thumb. Germany, Austria and Switzerland reward a pass: high walk-up fares, no compulsory supplements, board what you like. France and Spain punish one: cheap advance fares and a supplement on every fast train. Before buying, it is worth checking which of your trains actually require a reservation and when the booking window opens — the pass quota on a popular TGV can be gone months ahead.
Compulsory supplements come from a small quota that opens on the operator's own schedule. Find out when yours opens before it sells out.

Scope: The break-even arithmetic, travel-day accounting and validity checks are the durable part of this tool. Reservation fees come from the site's own reservation-rules data, checked in August 2026. Pass prices are indicative starting figures only — Interrail and Eurail reset them annually, which is why the price field is editable and why the tool asks you to enter the price you are actually quoted.
Primary references
“Is Interrail worth it?” cannot be answered in general, only for a specific itinerary — and the answer swings on costs the pass sellers do not put in front of you. This calculator adds the compulsory reservation fees to the pass price, counts travel days the way a flexi pass actually counts them, and charges any pass-refusing operator at full fare.
It then tells you the number that matters: how much point-to-point fare your trip needs before the pass pays for itself.
Four long German and Austrian legs worth €495 of tickets, spread over four days on a 5-day flexi pass: no compulsory supplements, so the pass costs its price plus optional seat fees and comes out well ahead. Swap the same four legs for TGV and AVE journeys with €160 of cheap advance fares, and the pass now carries €40–70 of compulsory reservations on top of its price — the identical pass loses badly on an identical number of trains.
Pass side = pass price (adjusted by traveller type and class) + compulsory reservation fees for the chosen services + full fares on operators that refuse passes. Ticket side = the sum of the fares you enter. Saving = ticket side − pass side, reported as a range wherever a reservation fee is itself a range, with the verdict taken on the midpoint. Travel days = distinct dates, undated journeys counted individually; a tier is only viable if it has enough travel days and enough validity to reach the last journey.
It depends almost entirely on which countries you travel in, not on how many trains you take. A pass wins in Germany, Austria and Switzerland, where fares are high, no reservation is compulsory and you can board freely. It usually loses in France and Spain, where advance point-to-point fares are cheap and every high-speed leg adds a compulsory supplement on top of the pass. Count the reservation fees before deciding — they are the cost most comparisons leave out.
Add the pass price to every compulsory reservation fee your itinerary will incur, plus the full fare for any operator that refuses passes. That total is your break-even: if the same journeys would cost more than it as ordinary tickets, the pass wins. Comparing the pass price alone against ticket prices is the standard mistake, and it can overstate the pass by a hundred euros or more on a France-heavy trip.
A calendar day on which you take any number of trains. Four journeys on one day consume one travel day; four journeys on four days consume four. This is why itineraries with identical trip counts can need different pass tiers, and why clustering journeys onto the same day is the single most effective way to stretch a flexi pass.
A direct night train departing after 19:00 uses only the departure day, and carries you into the next morning without consuming a second one. That makes a well-placed night train doubly economical: it saves a travel day and a hotel night at once. The couchette or sleeper reservation is compulsory and separately priced, so budget for it.
No, and this is the most common misunderstanding about passes. Compulsory reservations on TGV, AVE, Frecciarossa, Eurostar and every night train are charged on top, from a quota reserved for pass holders that is priced separately from ordinary tickets. On a France and Spain itinerary these fees can add a substantial fraction of the pass price again.
Italo in Italy and OUIGO in France and Spain are open-access operators outside the pass system entirely — a pass holder pays the full fare like anyone else. This calculator counts those journeys on the pass side, because treating them as covered would overstate the pass by a whole fare rather than by a reservation fee.
The youth price applies to travellers aged 12 to 27, taken on the first day of travel, and it is a 25% reduction — by far the largest single lever on whether a pass beats tickets. The senior discount for over-60s is much smaller at around 10%. Children aged 4 to 11 travel free on an accompanying adult’s pass, up to two per adult.
