The estimation of a preference-based measure of health from the SF-36' at: http://www.sciencedirect.com/science/article/pii/S0167629601001308

A computer algorithm for deriving a preference-based index from SF-36 data via the SF-6D is available from the corresponding author.

A wide range of utility scorings have been derived from SF36. If you have the raw data or means for the data items it requires, probably the best is the Sengupta SF12 scoring based on HUI2. (SF12 is a subset of SF36.) For a listing and citations to 25 scorings, see my article Quality of Life Loss of People Admitted to Burn Centers, United States, T Miller, S Bhattacharya, W Zamula, D Lezotte, K Kowalske,D Herndon, J Fauerbach, L Engrav, Quality of Life Research, 22:9, 2293-2305, 2013.  If you have SF12 or SF36 domain scores but not the raw responses, use the scoring in Lawrence et al. (2004). Another reasonable choice is the Franks et al. (2003) component scores based on MEPS. If you do not have the raw data and are working from published means, do NOT use a non-linear regression scoring that, e.g.,includes squared terms or cross-products. (I did not look back to see if  Lawrence or Franks included nonlinear terms.)

is there any excel algoritmm for calculating the Utility?

something May help you.and here a lot of algorithms mapping from special life quality assessment tools to EQ-5D

an paper :Mapping SF-36 onto the EQ-5D index: how reliable is the relationship?

will also be help and its algorithm based on stata.
