Best Efforts vs Reasonable Efforts: What You're Actually Promising
Contract language like "best efforts" and "reasonable efforts" appears everywhere, but few people understand the different levels of obligation these create. Knowing the difference can save you from overcommitting—or underdelivering.
The Efforts Spectrum
From most to least demanding:
- Best efforts (highest obligation)
- Reasonable best efforts
- Commercially reasonable efforts
- Reasonable efforts
- Good faith efforts (lowest obligation)
Best Efforts: The Highest Standard
A "best efforts" commitment means you must pursue the objective as if it were your own, potentially sacrificing other business interests.
What courts may require:
- Devoting significant resources
- Prioritizing this commitment over others
- Accepting financial losses to perform
- Doing everything possible short of bankruptcy
Warning: In some jurisdictions, "best efforts" has been interpreted to mean "all efforts" regardless of cost.
Commercially Reasonable Efforts: The Business Standard
This is often the best choice for business contracts. It means you must try hard, but within normal business parameters.
What it typically requires:
- Acting as a reasonable business would in similar circumstances
- Considering the importance of the obligation
- Not required to sacrifice your own business
- Not required to accept unreasonable cost or risk
Reasonable Efforts: The Middle Ground
Similar to commercially reasonable, but focuses more on what a reasonable person would do rather than a reasonable business.
Key characteristics:
- Effort proportional to the stakes
- Not required to take extraordinary measures
- May consider cost-benefit analysis
Why It Matters: A Comparison
| Scenario | Best Efforts | Commercially Reasonable |
|---|---|---|
| Other opportunities conflict | May need to prioritize this | Can balance against other interests |
| Achieving goal is expensive | Still must pursue | Can consider cost |
| Success is unlikely | Must keep trying | Can reassess approach |

Frequently Asked Questions
What's the difference between best efforts and reasonable efforts?
'Best efforts' is the highest standard—you may need to prioritize the commitment over other business interests and accept losses. 'Reasonable efforts' or 'commercially reasonable efforts' allows you to balance the commitment against normal business considerations and costs.
Which efforts standard should I agree to?
If you're making the commitment, prefer 'commercially reasonable efforts'—it allows you to balance against other business needs. Avoid 'best efforts' unless the commitment is truly your top priority. If you're receiving the commitment, 'best efforts' gives you stronger protection.
Can 'best efforts' require me to lose money?
Potentially yes. Some courts interpret 'best efforts' to require pursuing the goal even at significant financial cost. This is why 'commercially reasonable efforts' is often preferred—it explicitly allows consideration of business realities.
