Simple question about calculating amps on a circuit


I have what I believe should be an easy question but I can not find the answer anywhere. I am trying to calculate the load for a circuit breaker. I understand how to calculate the amperage for light fixtures etc.... where I am struggeling is how much do I assign for outlets so that I do not overload the breaker. For example I know that I am going to have say 5 150 watt max lights (150Watts/120volts=1.25 amps) therefore I have 5x1.25 amps used on the 15amp breaker so I have 8.75 apps "remaining". What value should I use for an oultet since you can plug in variouse devises that pull different loads?

Calculate the load on general-purpose receptacle-outlets on the basis of 1.5 amps-per-outlet.

It may not be as simple as PATTBAA suggested. Think about how you intend to use the receptacles. If you plan on using one for the iron and one for the vacuum cleaner, and you want to warm up your iron when vacuuming, then you clearly have a problem.
