Equipment Payments

Equipment payback calculator

Find out whether a piece of equipment pays for itself, and how fast. Enter what it costs, what it earns or saves you a month, and what it costs to run, and see the monthly net, the payback period, and the profit over five years, so a machine that sounds like it prints money has to prove it first.

§ 01 Your numbers

Change anything. The answer updates as you type.

The all-in cost to buy and install it. If you are financing, use the all-in cost, and check the loan calculator for the payment.
What the machine actually brings in, or saves, each month: new work you can take, labor it replaces, or a service you stop paying for. Be honest and conservative here.
Fuel or power, materials, maintenance, and any operator time the machine adds. The line people forget, which is why so many machines disappoint.
Net gain per month

  • Added revenue or savings, per month$2,000
  • Cost to run it, per month$400

Paying for itself in under about a year and a half is a strong purchase, if the benefit is real. Confirm you can fill the capacity, then buy with confidence.

What this assumes, and where it could be wrong

Every one of these is a place the number could be off. They are here because you should be able to check our working, not because we are hedging.

A MACHINE PAYS FOR ITSELF OUT OF THE NET, NOT THE REVENUE.
The number that matters is what the equipment earns or saves you MINUS what it costs to run. A machine that brings in $2,000 a month but costs $400 to run nets $1,600, and it is the $1,600 that pays down the purchase. Counting the gross revenue and ignoring the running cost is exactly how a machine that looked like a two-year payback turns into a four-year one

Be conservative on the benefit. The added revenue only counts if you can actually sell the extra capacity, and the savings only count if you genuinely stop paying for something. A machine that can do more work does not pay for itself until that work exists; capacity you cannot fill is a cost, not a benefit.

The payback period is the cost divided by the monthly net, and if the net is zero or negative there is no payback at all. The calculator shows a five-year net profit for exactly this reason: if that number is negative, the machine does not pay for itself in five years, however good the monthly revenue looks.

This ignores the time value of money and the financing cost. A dollar earned in year five is worth less than one earned now, and if you borrowed to buy the machine, the interest is a real cost this simple payback does not subtract. Both make the true payback a little slower than the arithmetic here; for a large purchase, take it further with an accountant.

The defaults are ours and are a starting point. The cost, the benefit, and the running cost are yours, and the honesty of the answer is entirely in how honestly you fill the benefit line.

Frequently asked questions

How do I know if equipment will pay for itself?
Work out the monthly net (what it earns or saves you, minus what it costs to run), then divide the purchase cost by that net to get the payback period in months. If the net is zero or negative, it never pays for itself. The calculator above does this and also shows the five-year profit, which tells you at a glance whether it clears its own cost.
What is a good payback period for equipment?
It depends on the equipment's useful life, but a machine that pays for itself in well under its lifespan leaves years of profit after, while one whose payback approaches its lifespan barely breaks even. A payback of a year or two is excellent; one approaching five years needs the machine to last well beyond that and the benefit to hold up.
What is the most common mistake in an equipment payback?
Counting the revenue and forgetting the running cost, and assuming the added capacity is automatically filled. A machine only pays for itself out of the net, and only if the extra work actually exists. Overstating the benefit line is why so many purchases that penciled out beautifully disappoint in practice.
Should I include financing in the payback?
This calculator does not, to keep it simple, but the interest is a real cost that makes the true payback slower. If you are financing, the honest version subtracts the loan's monthly payment from the benefit, or treats the interest as part of the cost. For a large purchase, it is worth running it both ways.

The monthly payment is not the cost. The interest over the term is, and a long term hides a large one behind a comfortable payment.
