The average IQ is 100 regardless of age. IQ is intelligence, which does not change too mouch during ones life. Yes, it can improve through the years, and when you are older it begins to deteriorate. But in general it remains the same.
The person before me(at least that I last saw) said to not trust online tests. I agree to a certain extent, though if you take multiple one you can average the score and come out fairly accurately. I have, myself, taken only 2. On the first I recieved a 127, and on the second a year later I recieved a 140. I greatly doubt that I got that much smarter... :) I expect I'm somewhere around 130-135.

Here's what I found and you can use the formula to confirm: The IQ Measure
During the test revision, Binet and Simon developed the concept of mental age. The five-year-old who could pass only the three-year-old tests was said to have a mental age of three. A child whose chronological age (CA) and mental age (MA) were both five was considered to have normal intelligence. Later, a German psychologist, William Stern, devised the intelligence quotient (IQ) using the CA and MA. The formula he developed was:
IQ = MA/CA X 100
Thus the child with an MA of 3 and CA of 5 would have an IQ of 60. The "normal" five-year-old has an IQ of 100. The five-year-old with an MA of 7 has an IQ of 140 (7/5 X 100) Computational formulas had to be modified later, however, for the measurement of adult intelligence which is not presumed to be directly variable with age.
If a score at the 50th percentile is presumed to represent the performance of an average person, we can make that score equal to an IQ of 100. By various other statistical procedures it is possible to relate values of IQ to this distribution. Figure 8 illustrates that comparison.

The average IQ is 100. The I.Q. itself includes the subject's age in the calculations. A 15 year old person is not expected to know what a 25 year old should know.
If the 25 year old took the 15 year old's test, she might appear smarter until one realized that she was only smarter if she were still 15, meaning she wasted 10 years.
Whatever your I.Q. score is, it is that for whatever age you are . . . unless you took an Internet I.Q. "test." I've administered these tests, and had them administered to me, and they are unreliable enough when done by professionals. If one does it on her own, it really is not a valid result.

Average IQ is defined as 100

An average IQ is always 100. If you are not yet an adult, the Stanford-Binet, I believe, adjusts according to your age.
One hundred is average by definition. The scores are transformed mathematically -- normalized and indexed -- so that 100 is exactly in the middle.

Average is around 100. However, testing must be done under controlled circumstances, with professional administrators, and certified tests.
