Peak season: how to add cars without paying for them all year
Tourism, distribution, installation and agriculture all have peak months. How to separate the stable core of your fleet from the cars you need only in season, how to work out when a subscription is worth it and when to request a quote.

In short
Don't size your fleet for the peak months. Keep only the stable core on a lease or in ownership (the minimum number of cars used every month) and add the seasonal cars through a car subscription of 1 to 12 months, for exactly as long as the peak lasts. That way you pay only for the cars your team uses.
- You have three options: a fleet sized for the peak (cars sitting in the car park off-season), a fleet sized for the average (too few cars exactly when you have the most business), or a stable core plus flexible capacity.
- The stable core is the monthly minimum of cars used over the last 12 months. Anything above it is seasonal capacity.
- The cost rule: a seasonal car on a subscription works out better than an extra car all year as long as its monthly cost stays below 12 ÷ (peak months) times the monthly cost of a leased car. With four peak months, the threshold is three times.
- Request a quote for your seasonal cars 6–8 weeks before the peak, so you have a choice of category and handover location.
Who it's for
- Fleet and operations managers
- SME managing directors and finance directors
- Tourism, distribution, installation, agriculture, construction
- Sales teams running campaigns
In December, a consumer goods distributor makes twice as many deliveries and store visits as in February. A seaside hotel triples its staff between June and August. An air-conditioning installer can't keep up with installations from May to August. Demand grows, the team grows, and the number of cars… stays the same.
A fleet is usually sized once a year, at budgeting time, and contracted for several years. Seasonal activity doesn't follow the budget, though. This guide helps you find out how many cars you really need, in which months, and how to add them without paying for them all year.
What a busy season means for your fleet
Almost every business in Romania has a rhythm to its year. Only the months differ. Tourism peaks in summer on the coast and in winter in the mountains, distribution before Easter and Christmas, construction and installation between spring and autumn, agriculture during the sowing and harvest campaigns. In all these cases, the number of people in the field changes from one month to the next, and the need for cars follows the same curve.
Why a fixed fleet doesn't suit a seasonal business
When demand varies, a fixed fleet leaves you with two equally awkward options. You can see both in the calculator below, with your own data.
- Size the fleet for the peakYou have cars for everyone in season, but for the rest of the year some of them sit in the car park. You pay the rate, insurance, parking and administration for cars nobody uses.
- Size the fleet for the averageThe cost looks lower, but in exactly the months with the most business your team has nothing to travel in. Then come reimbursed personal cars, last-minute daily rentals and postponed call-outs.
- Separate the stable core from flexible capacityYou keep long term only the cars used all year and add the rest only for the peak months. Every car you pay for is a car that gets used.
The stable core + flexible capacity model
The idea is simple: you split the fleet into two layers, with different rules. The base layer stays as you have it today, on a lease or in ownership. The seasonal layer comes from short car subscriptions and changes from one year to the next, as demand dictates.
- Stable core
- The number of cars used in every month of the year. It's calculated as the monthly minimum over the last 12 months and can stay on an operating lease or in ownership.
- Flexible capacity
- The cars you need only in the peak months. They come from a 1–12 month car subscription and are handed back when the season ends.
- Car-month
- One car used for one month. It's the unit you compare the options with: 10 cars for 3 months is 30 car-months.
- Utilisation rate
- How many of the car-months you pay for are actually used. A fleet sized for the peak has, by definition, a utilisation rate below 100%.
An example: 20 cars all year and another 8 for four months
A distribution company uses 20 cars every month and another 8 between September and December. If the fleet were sized for the peak, it would have 28 cars for 12 months. With a stable core plus a subscription, it has 20 cars all year and 8 cars for just four months.
- 336car-months paid for with a fleet sized for the peak (28 × 12)
- 272car-months with core + subscription (20 × 12 + 8 × 4)
- −19%car-months paid for, with the same cover in season
- 0cars without a driver in the eight off-season months
What it costs: when a subscription is worth it for seasonal cars
Let's be fair: per month, a car subscription of a few months usually costs more than the same car on a multi-year operating lease. Flexibility has a price. But the right question for seasonal cars isn't how much they cost per month, but how many months you pay for.
A seasonal car on a subscription works out better than an extra car all year as long as its monthly cost stays below 12 ÷ (peak months) times the monthly cost of a leased car.
- 2-month season: the subscription can cost up to 6 times more per month and still work out better.
- 3-month season: the threshold is 4 times.
- 4-month season: the threshold is 3 times.
- 6-month season: the threshold is 2 times.
- Beyond 8–9 months a year, the car most likely belongs in the stable core.
Always compare the total monthly cost of each option: the rate, insurance, maintenance, tyres, administration. And for a car that would sit in the car park off-season, add what doesn't appear on the invoice: the parking space, the time of whoever manages it, the risk of an unused car deteriorating.
How to work out how many cars you need, in 5 steps
- Gather the data for the last 12 monthsHow many cars were actually used each month: logbooks, GPS reports, personal car expense claims, daily rentals. These are all cars you needed.
- Find the stable coreThe monthly minimum is the number of cars you use all year. These stay in the main contract.
- Measure the peak and how long it lastsThe difference between the peak month and the core gives you the number of seasonal cars, and the months in which you go above the core give you the subscription term.
- Add a margin for growthIf this year you have more clients, more projects or a bigger sales team, adjust the peak. Better an extra car confirmed in time than one hunted for in the last week.
- Check the cost ruleFor each car above the core, compare the months it's used with the 12 ÷ months threshold. Anything over 8–9 months a year can move into the core.
When to request a quote for the season
Seasonal cars are planned like seasonal staff: in advance. The earlier you request a quote, the more choice you have of category, number of cars and handover location. The calendar below starts from the month your peak begins.
Also for sales teams and campaigns
Sales teams change often: new reps, new territories, launch campaigns. Cars for a campaign or for a new rep's first months can come from a subscription, without changing your core fleet contracts. If the rep stays, their car can move into the stable core at the next budgeting round.
When you don't need a subscription
A subscription isn't the answer to everything. If your needs are stable all year, a multi-year operating lease usually remains the better fit. If the peak lasts only a few days (an event or a trade fair, for example), a daily rental is simpler. The 1–12 month subscription covers the ground in between: peaks of one month or more that recur but don't last all year.

Frequently asked questions
What is an extra fleet for the season?
It's the cars a company needs only in its peak months, on top of the stable core used all year. You can take them on a 1–12 month car subscription and hand them back at the end of the season, without changing your core fleet contracts.
Is a car subscription more expensive than an operating lease?
Per month, usually yes: the flexibility of a short term is reflected in the price. For cars used only a few months a year, though, the annual cost can be lower, because you pay only for the months of use. The subscription works out better as long as its monthly cost stays below 12 ÷ (peak months) times the monthly cost of a leased car.
Can I combine an operating lease with a MiniLease subscription?
Yes, and it's the model we recommend to companies with seasonal activity: a lease or ownership for the stable core, a subscription for the seasonal cars. The two contracts are independent.
How long can I take cars on a subscription for?
A MiniLease subscription runs for 1 to 12 months. You choose the term to match the length of the season, and at the end you can review what you need: extend, reduce the number of cars or hand them back.
What happens if the season runs longer?
At the end of the subscription period you can extend for the cars you still need. Let us know in good time, so we can keep the same cars for your team.
How long before the season should I request a quote?
We recommend 6–8 weeks before the peak begins. That gives you time to choose the category and number of cars, agree the handover location and get your team ready.
What categories of car can I take for the season?
The MiniLease fleet has six categories: economy, compact & crossover, estate & 7 seats, SUV, premium and 8+1 seats. Field teams often use estate cars, and 8+1 seaters are used to transport teams.
Can I use the subscription as an individual, for a few months a year?
Yes. MiniLease also has an option for individuals, for people who need a car for only a few months, not permanently.
