Truck EMI vs profit: why a profitable truck can still run short of cash

Your accountant says the truck made a profit. Your bank balance says otherwise. Both can be right. This guide shows why, with a worked example, and how to check whether a truck will pay for itself and its loan.

In short

An EMI has two parts. Interest is a cost. Principal repays the loan and is not a cost.
Depreciation reduces profit but costs no cash in the month it is counted.
When the principal you repay is larger than the depreciation you count, profit can be positive while cash is negative.
For a loan, the test is simple: does the month's operating cash cover the whole EMI?

Three numbers that get mixed up

When people ask "is my truck making money?", they can mean three different things:

Number	What it answers	What it subtracts
Operating profit	Does the truck earn more than it costs to run?	Trip costs and fixed running costs
Accounting profit	Is the business profitable on paper?	Running costs + interest + depreciation
Cash after the EMI	Is there money left in the bank at month end?	Running costs + the whole EMI

Accounting profit subtracts interest and depreciation. The cash view subtracts the full EMI, both interest and principal, and ignores depreciation, because no money leaves your account for it. These can point in opposite directions.

The example truck and its loan

Take a truck bought for ₹36 lakh with ₹6 lakh down and a ₹30 lakh loan at 10% a year for 5 years (example figures). On a reducing-balance loan the EMI works out to:

EMI = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1) = ₹63,741 a month

Here P is ₹30,00,000, r is the monthly rate (10% ÷ 12) and n is 60 months. The EMI stays the same every month, but what is inside it changes:

How the same ₹63,741 EMI splits over the loan

Month 1: interest / principal	₹25,000 / ₹38,741
Month 12: interest / principal	₹21,297 / ₹42,444
Month 36: interest / principal	₹11,943 / ₹51,798
Month 60: interest / principal	₹527 / ₹63,214
Total interest over 5 years	₹8,24,468

For depreciation, assume the truck is expected to be worth ₹12 lakh after 10 years. Spreading the ₹24 lakh loss of value evenly gives ₹20,000 a month. This is a planning assumption. Depreciation for tax follows separate rules.

One month, three answers

The truck completes 6 trips in the month. Each trip brings ₹52,000 of freight and costs ₹35,000 in diesel, tolls, driver allowance and wear, so each trip contributes ₹17,000. Fixed running costs (driver salary, insurance, permits, road tax and so on) are ₹47,000 a month.

Worked example: month 1 of the loan

Freight: 6 trips × ₹52,000	₹3,12,000
Trip costs: 6 × ₹35,000	− ₹2,10,000
Fixed running costs	− ₹47,000
Operating profit	₹55,000
Interest (month 1)	− ₹25,000
Depreciation	− ₹20,000
Accounting profit	₹10,000
Operating profit	₹55,000
Full EMI (interest + principal)	− ₹63,741
Cash after the EMI	− ₹8,741

On paper the truck made ₹10,000. In the bank it lost ₹8,741, and that gap has to come from savings, another truck or the owner's pocket.

Why? The cash view pays ₹38,741 of principal that the profit view never sees. The profit view instead charges ₹20,000 of depreciation that costs no cash this month. ₹38,741 − ₹20,000 = ₹18,741, which is exactly the gap between +₹10,000 and −₹8,741.

It gets more confusing over time. By month 36 the interest falls to ₹11,943, so accounting profit rises to about ₹23,000 a month. The EMI is still ₹63,741, so the cash shortfall is unchanged at ₹8,741. The accounts improve while the bank balance doesn't.

How to tell if a truck can carry its loan

Ask how many trips the month needs to cover running costs and the full EMI. Each trip contributes ₹17,000, so:

Trips for cash break-even = (fixed costs + EMI) ÷ contribution per trip

Worked example: trips needed

To cover fixed running costs: ₹47,000 ÷ ₹17,000	3 trips
To also cover the EMI: (₹47,000 + ₹63,741) ÷ ₹17,000 = 6.5	7 trips
To also pay the owner ₹25,000: ₹1,35,741 ÷ ₹17,000 = 7.98	8 trips

At 6 trips a month this truck can't carry its loan. It needs a seventh trip just to stop losing cash, and an eighth before the owner takes anything home. Whether 8 trips actually fit in a month depends on how long each round trip takes. Our guide on how many trips a truck can really do in a month covers that.

Ways to close a cash gap

Raise the contribution per trip. Even ₹1,500 more per trip across 6 trips is ₹9,000 a month, which closes this gap. Check whether your rates cover the full cost first: see how to calculate break-even freight.
Cut empty running. A return load, even at a lower rate, can turn empty kilometres into contribution.
A larger down payment lowers the EMI from the start, if you have the cash.
A longer tenure lowers the EMI but raises the total interest. It helps monthly cash and costs more overall, so compare both before choosing.
Plan for the gap. If a shortfall in the early months is expected, keep a cash buffer to cover it rather than discovering it later.

Common questions

Is a truck EMI an expense?

Only partly. Each EMI contains interest, which is a cost of borrowing, and principal, which repays the loan and is not an expense. In the books, the cost of the truck itself is spread over its life as depreciation instead.

Why does my profit go up each year when my EMI stays the same?

Because the interest part of a reducing-balance EMI shrinks every month while the principal part grows. Profit only counts the interest, so it rises. The cash you pay each month doesn't change.

Does a longer loan tenure help cash flow?

A longer tenure lowers the EMI, which can close a monthly cash gap. But you pay more interest in total, and you may still owe money when the truck needs major repairs or replacement. Compare both the monthly cash and the total cost before choosing.

Should I include depreciation when deciding whether to take a load?

For a single load, compare the freight with the trip's direct costs plus a share of fixed costs. Depreciation and the EMI belong to the question of whether the truck as a whole pays for itself, which you check month by month.
