Fleet Expansion
Simulator
Enter your current fleet, the growth you're looking for, and each unit's numbers to know exactly how much to invest and when you recover the capital.
To expand a truck fleet in Mexico profitably, the general rule is to make sure each new unit pays for itself with the income it generates before acquiring the next one — the recovery period shouldn't exceed 36 months. The main factors are the purchase price or credit, the average income per km, the operating costs, and the current fleet's utilization rate. This simulator calculates how many units to add, how much to invest, and in how many months you recover the capital.

Frequently asked questions
How many units do I need to grow my fleet by 30%?
It depends on your current size. With 5 units and 30% growth you need to add 2 units. With 10 units, you need 3. This calculator determines it automatically and projects the impact on income, profit, and required investment.
How long does it take for a transport unit to pay for itself in Mexico?
In freight trucking, payback on own capital (down payment) is typically between 18 and 36 months, depending on the operating margin and route type. A unit with a 20-25% margin and a 30% down payment usually pays back in 18-24 months.
When is the right time to expand?
The key signals are: you have demand you're turning away due to lack of capacity, your units operate at more than 85% capacity, you have positive cash flow for the down payment, and the current operating margin exceeds 15%. Expanding without confirmed demand or without capital for the down payment can compromise the operation.
What does the operating cost per unit include?
The monthly operating cost per unit should include: fuel, driver payroll (including social security and benefits), preventive and corrective maintenance, vehicle insurance, tires (prorated monthly), and any other recurring expense. Don't include the unit's credit payment, since payback is calculated on the own capital.
Signs your fleet is ready to grow
Before investing in new units, verify that these conditions are met:
Confirmed demand
You have customers or contracts you can't serve due to lack of capacity, and this demand is sustained (not just temporary spikes).
Utilization above 85%
Your current units operate more than 85% of working days. An underutilized fleet doesn't justify expansion.
Operating margin above 15%
Each current unit generates real profit after all costs. Expanding with units that aren't profitable only multiplies the losses.
Cash flow for the down payment
You have liquidity to cover 20-30% of the down payment without compromising your current fleet's operating capital.
