How do you calculate the annealing temperature for PCR?

The optimal annealing temperature (T a Opt) for a given primer pair on a particular target can be calculated as follows: T a Opt = 0.3 x (T m of primer) + 0.7 x (T m of product) – 14.9; where T m of primer is the melting temperature of the less stable primer-template pair, and T m of product is the melting temperature of the PCR product [1].
