How Is the Impact Calculated?
- New revenue = revenue × (1 + revenue change %)
- New costs = costs × (1 + cost change %)
- Profit = revenue − costs
- Change in profit = new profit − old profit
Example: A company has $10 million in revenue and $8 million in costs, so its profit is $2 million. A news event cuts revenue by 5% and raises costs by 3%. Revenue falls to $9.5 million and costs rise to $8.24 million. Profit drops to $1.26 million, a 37% fall.
Why Can Small News Move Profit So Much?
Profit is what is left after costs. When costs stay high and revenue slips, the whole drop comes out of that smaller profit. That’s why a 5% revenue drop can cut profit by far more than 5%.
Real Example: Ford in 2025
Ford’s revenue rose 1% in 2025, to a record $187.3 billion. Yet the company swung from a $5.9 billion profit in 2024 to an $8.2 billion net loss in 2025 (Ford). The difference came from costs: the results included about $10.7 billion in charges tied to its electric vehicle business and canceled EV programs. Revenue barely moved, but profit changed by more than $14 billion.

What the Business News Impact Calculator Can and Cannot Tell You
It can show how much a change in revenue or costs could move profit, and how sensitive profit is to small changes.
It cannot:
- Tell you whether the news is true. Check it first with our guide on how to verify business news.

Frequently Asked Questions
What does a business news impact calculator do?
A business news impact calculator estimates how a news event could change a company’s profit. You enter the company’s revenue and costs, plus how much the news might raise or lower each one. The calculator then shows the new profit and the change in dollars and percent.
Why does a small revenue drop cut profit so much?
Profit is only the amount left after costs. If revenue falls while costs stay the same, the whole loss comes out of profit. For a company with a 20% profit margin, a 5% revenue drop with no cost savings cuts profit by 25%.
Where do I find a company’s annual revenue and costs?
For US public companies, look at the latest earnings release on the company’s investor relations website or its annual report (Form 10-K). Both are free on the SEC’s EDGAR database. Revenue is usually at the top of the income statement.
Can this calculator predict a company’s stock price?
No. It only estimates the effect on profit based on the numbers you enter. Stock prices also depend on investor expectations, interest rates, and overall market conditions. Use the result as a starting point for analysis, not as investment advice.
How do I estimate the revenue or cost change from a news event?
Start with what the company itself says, such as guidance in an earnings release or details in a filing. If the company hasn’t said anything, use a range: try a small, medium, and large change to see how sensitive profit is.
Final Takeaway
A small change in revenue or costs can have a much bigger effect on profit. Use the calculator above to test the numbers behind a headline, then confirm them in the company’s own filings before drawing conclusions.
