Warranty Work Pricing

The Hidden Cost of Warranties
(And How to Stop Them From Eating Your Profit)

When you think about your pricing, you’re probably focused on labor, materials, and overhead. But there’s one cost that often gets overlooked and quietly eats away at your profit: warranty work.

Let’s break down what’s really happening and how to fix it.

What Is Warranty Work, Really?

Warranty work is any job you go back to fix or redo after the original work is completed. You’ve guaranteed your service, so when something needs attention, you return and make it right.

The problem? Most of the time, you’re not charging for it.

That means every callback, repair, or replacement becomes a direct expense to your business. Labor, materials, time - it all adds up, and it’s coming straight out of your bottom line.

The Profit Leak Most Contractors Miss

If warranty work isn’t built into your pricing, you’re essentially paying for it yourself.

This is one of the most common ways contractors lose money without realizing it. You’ve got the revenue from the original job, but when warranty work pops up, there’s no cushion to absorb the cost.

The result: shrinking margins and profits that don’t reflect the effort you’re putting in.

The Good News: Warranty Costs Are Predictable

Here’s the key insight most business owners miss: warranty work is not random.

Even large, well-run companies typically see warranty-related costs fall somewhere between 3% and 10% of revenue.

That means you can plan for it, price for it, and control it.

How to Start Accounting for Warranty Costs

If you already have historical data, use it. Look at past warranty-related expenses and calculate what percentage of your revenue they represent.

If you don’t have that data yet, start simple:

• Choose a starting point (5% is a common baseline)

• Begin tracking all warranty-related expenses

• Adjust over time as you gather real numbers

The most important step is to start tracking now.

How to Track Warranty Work

You need visibility before you can make smart decisions.

Inside your accounting system (like QuickBooks Online), you can:

• Create a specific category for warranty expenses

• Use tags to label warranty-related transactions

• Track labor, materials, and callbacks tied to warranty work

Over time, this data will show you patterns and help you make better decisions about pricing, training, and operations.

How to Build Warranty Costs Into Your Pricing

Once you understand your numbers, you have a few options:

1. Increase overall pricing
Add a small percentage (like 5%) across your services to cover expected warranty costs.

2. Adjust your hourly rate
For example, if you typically charge $125/hour, you might increase it to $135/hour to create a buffer.

3. Blend it into your cost structure
Incorporate warranty coverage into how you calculate your margins on every job.

The goal is simple: make sure warranty work is funded by your pricing, not your profit.

How to Reduce Warranty Costs

Pricing helps you cover the cost. But reducing warranty work altogether is even better.

Focus on:

• Training your team for consistent quality

• Using higher-quality materials

• Identifying repeat issues or problem areas

• Evaluating whether problems come from labor, products, or processes

Warranty work is feedback. Use it to improve your business.

The Bottom Line

You can’t afford to ignore warranty costs.

They are predictable. They are trackable. And if they’re not built into your pricing, they will quietly drain your profits.

A strong business doesn’t just deliver quality work. It also protects its margins by planning for the real costs of doing business.

Know your numbers. Own your future.
