EstimatesPlease
by Berdwire

  Do you do estimates? Do you calculate price quotes? Forecast profits? Measure construction costs or guesstimate quantities of goods?

You know you can't just use your calculator for estimates. With your calculator, you need to enter exact numbers. What you have is numbers like "between 50 and 75" or "approximately 5". 

What you can use is EstimatesPlease.

With EstimatesPlease you can enter numbers like "between 50 and 75" or "approximately 5".

With EstimatesPlease you don't even need to know if certain numbers exist at all. For example, let's say you're not sure if a $40 transaction is coming in. Maybe it will, maybe not.

With EstimatesPlease you can just enter "possibly + 40".

After you've entered your equation and clicked =, EstimatesPlease will return a set of five estimates. These range from the "lowest-possible-case" estimate to the "highest-possible-case" estimate.

You decide if you want to be cautious, optimistic or somewhere in the middle.

You'll estimate anything quickly and confidently--and make a better informed decision.
