Car Rental: Fleet Utilisation and Depreciation, Not Just the Number of Cars

«We have 22 cars. At peak season, from May to September, the till comes to nearly ₴900,000 a month. Yet in February I sit down to work out the leasing and there's nothing to pay it with. The yard is packed with cars, and there's no money for the new season. For a long time I couldn't work it out: there's a pile of cars, they're out driving — so where does it all go?» — that's how Ihor, the owner of a car rental company, opened our conversation.

Sound familiar? The fleet grows, your Instagram shows new crossovers, clients book weeks ahead. Yet by the end of winter the account is empty, and every leasing payment turns into a quest. And the first thought is always the same: «I need more cars, more ads, more bookings.» Yet the trouble is almost never the number of cars.

The trouble is that a rental company is counted as a single till. Everything that comes in from rentals goes into one pot. Leasing, insurance, repairs, car washes, fines — all from that same pot. And while the numbers are blended together, you can't see one simple thing: one car earns you ₴18,000 net a month, while another quietly runs a loss, because it sits in the yard and keeps eating its leasing and hull insurance. Both look the same — shiny, insured, «in service.» But only one of them feeds you.

This article is about breaking the rental business into small pieces: by each car, by season, by real cost. So you can finally see which car brings the money and which just stands there looking pretty while it eats your budget.

How Ihor Got to 22 Cars

Ihor started without any business plan. There was one Skoda of his own, which he rented out to acquaintances on weekends while he drove a taxi on the side. Then a second car, on credit. Then a third. Demand was there, clients came back, and every spare hryvnia went straight into the next vehicle — mostly on leasing.

In four years, one Skoda grew into a fleet of 22 cars: economy class for daily rental, a few crossovers for families and tourists, a couple of cars «for weddings and photo shoots.» It looked like success — both from the outside and in the feed. But the bigger the fleet grew, the more often Ihor caught himself thinking: turnover is rising, yet the money in the account isn't. Each new car was supposed to bring profit, and instead it added one more leasing payment and one more insurance policy.

«I thought I was earning on turnover. In fact I was just shuffling money from rentals into leasing and back — and less and less of it between those two piles was mine.»

How the Money Really Works in Car Rental

In car rental, profit is decided not by bookings but by four things almost no one counts separately: the utilisation of each car, its real cost, depreciation and seasonality. Let's take them in turn.

Fleet Utilisation: Idle Time Is a Pure Loss

Picture each car as a little shop on wheels that you took on lease. It's available for rental about 30 days a month. How many of those days it actually drives for money — that is its utilisation.

Here's a sobering number. An economy car on lease costs you roughly ₴14,000 a month just for the «shell»: the leasing payment, hull insurance, road tax, a share of servicing. That's a cost that drips every day regardless of whether the car drives or sits. That works out to about ₴470 a day — before fuel, car washes and wages.

That means a simple thing: every day the car sits in the yard is minus ₴470 you've already spent but earned nothing on. If a car runs at 40% instead of 70%, it quietly eats thousands of hryvnias every month — and you never see it, because the shared till has no separate line for «idle-time loss.»

Measure utilisation honestly: not «how many bookings» but how many paid days out of the available ones. It's one of the most important numbers in a rental business, and almost no one tracks it per car.

The Real Cost per Car: Rental Isn't Profit Yet

A client paid ₴1,500 for a day — and the till shows a nice sum. But how much of it is really yours? Take away the fuel (if the car came back not refuelled), the wash after every client, a share of leasing and insurance for that day, minor service — and ₴1,500 quickly turns into ₴600–700 of margin. And if that week the car sat in the workshop twice and came back dirty three times — then even less.

The formula here is childishly simple, and that's exactly why you can trust it: revenue minus direct costs minus car upkeep = the car's margin. Direct costs are fuel, wash, minor repairs after a rental. Upkeep is leasing, hull insurance, servicing, tax. First learn to see the margin per car, not for the whole fleet in a lump — and half the fog clears.

Depreciation: the Invisible Cost Everyone Forgets

Here's the most treacherous one. A car you bought for ₴700,000 is worth ₴480,000 two years later. That difference — ₴220,000 — is also your cost, it just doesn't arrive as an invoice in your inbox. Every kilometre of mileage, every season of intensive rental writes very real money off the car's value.

Most rental companies don't count this — and so are genuinely surprised when the time comes to sell the car and buy a new one. It turns out that over the years of rental the car «earned» a pile of turnover, but half of that turnover was eaten by the loss of value that no one built into the daily rate. Depreciation isn't an accounting abstraction. It's a real fund for renewing the fleet, one that should accumulate with every rental. If you don't set it aside, the money for a new car will again have to come from leasing, and the circle closes.

Seasonality: Summer Feeds, Winter Eats

Car rental breathes with the season. May to September is the peak: tourists, weddings, holidays, utilisation near 80%. November to February is the slump: demand halves, while leasing, insurance and taxes are paid just the same every month, as if nothing had happened.

That's where the «no money for the new season» comes from. In summer the till roars, and it feels like you can afford one more car. You take it on lease — and add yourself one more fixed payment you'll have to carry through dead February too. The profit of the peak months shouldn't be eaten but set aside for winter payments and spring fleet prep. Those who don't do this start the same «where do I find money for the lease» quest every February.

Life Before Finmap

Most often the owner of a rental company comes to me with lines like these:

• «In summer there's plenty of money, but by March I could sell cars just to close the leasing.»
• «I have 22 cars, but I couldn't tell you which one actually earns and which just drives itself to the workshop.»
• «I bought another crossover because there was demand. Now it sits more than it drives — and drags me down.»
• «Client deposits, rental money, leasing payments — all on one account. I don't know where my money ends and someone else's begins.»
• «A car got damaged, the repair ate the whole month's margin on it, and I only noticed at the end of the quarter.»

Behind each of these lines is the same thing: the rental business is counted as a till, not as margin per car and per season. That's exactly how it was with Ihor — an Excel where the admin logged bookings, and a banking app where everything blended into one pile. Client deposits sat on the same account as working capital, so in peak months it looked like there was more in the account than there really was. And then a client returned a car — and the deposit had to be given back out of «nowhere.»

«I lived season to season, like on a swing. In summer a king, in winter a beggar. And every year the same thing, as if for the first time.»

How Ihor Got Things in Order

We started simple — by separating the money and seeing each car on its own. Ihor set up each car as a separate line and began tagging every payment: which car, which rental type (day / week / long-term / wedding), and separately — whether it was a deposit or a rental.

Then we allocated the costs. Leasing, hull insurance and tax were «tied» to a specific car — now each car carries its own cost instead of hiding in the shared pot. Fuel, wash and repairs were also logged per car. And separately we set up a depreciation fund: from every rental, set aside a nominal 10% for the future renewal of the fleet.

By the very first month the picture became almost uncomfortably clear. The two premium «wedding» cars Ihor was proud of brought a loud till, but after leasing and expensive hull insurance they left less than a modest economy car that drove almost every day. And one crossover, taken «because there was demand,» sat 18 days out of 30 — and was a pure minus.

Finances Now

Six months on, Ihor stopped looking at the total till and started looking at the margin per car. Here's how it looked for three telling cars in an ordinary off-season month.

See the trick? The most expensive and prestigious car in the fleet brought a minus in the off-season — because the high leasing and hull insurance weren't covered by six days of rental. While the modest economy no one paid attention to quietly fed the business.

Ihor didn't rush to sell the premium — he moved it to a different model: raised the price for seasonal dates, took it off the daily price list and left it only for events, where the margin is high. The idle crossover he moved into long-term rental for a corporate client — a lower daily rate, but a steady 30 days of utilisation instead of 17. And the two weakest cars he sold while they hadn't yet lost their value, closing part of the leasing with them.

Most importantly — Ihor started seeing the season ahead. In Finmap he set a plan by month: how much he expects in summer, how much will slump in winter. And now the profit of the peak months isn't «eaten» but goes into a cushion for the winter leasing payments. For the first time in four years, February passed without the «where do I find money» quest.

«Revenue is loud. Margin per car is quiet. And what I spend is the margin, not the revenue.»

How It Works in Finmap

All this maths works only when you see it every day — not once a quarter in a battered Excel. Here's how it looks in Finmap.

• Bank integrations and auto-import. Payments from the account pull in on their own; all you do is tag the car and the operation type. Deposits are kept separate from rentals — and you no longer confuse someone else's money with your own.
• Lines by car. Each car is a separate line with its own income and costs. You see the margin per car, not «the fleet average.»
• Cash Flow and P&L. One report shows the movement of money, the other the real profit with depreciation counted as an asset. You finally see the difference between «there's money in the account» and «the business is profitable.»
• Payment calendar for leasing. All leasing payments, insurance and taxes — laid out on the calendar in advance. You see cash gaps before they happen and never land in a February with no money.
• Plan vs. actual for the season. You set expectations by month and compare with the actual. The peak is no longer «eaten» but works for the winter.

And most importantly — this isn't bookkeeping «for the tax office.» It's your rental control panel: which car earns, which eats the budget, and what to pay the leasing with in the dead season. That is the very order in finances where decisions are made on numbers, not on gut feeling.

If you want to dig deeper into what earnings on a single car are even made of, read how to calculate the unit economics of a small business. And if what hurts is precisely the «there's turnover but no money» — here's a separate breakdown of why there's profit but no cash in the account. And so the peak isn't eaten again — how to compare plan and actual by month.

You don't need more cars. You need to see which car feeds the rental business, and which quietly eats it up in the yard.

Money Doesn't Disappear. You Just Don't See It.

Money in a rental business never disappears. It simply dissolves between cars, seasons and leasing payments while you stare at one shared till. The moment you break it apart by each car's margin and build depreciation and the season in ahead of time — it becomes clear what feeds the business and what merely stands there pretty, eating the budget. Finmap shows this every day, in simple numbers an owner will understand — not just an accountant.
