# Valuation growth rate for perpetuity

What would be reasonable rates of return for the computation of perpetuity in firm valuation?

I tend to google FMI's expected World GDP growth rate, but I can't always find results.

Would someone have any suggestions of methodologies for the estimation of these rates and sources for the required inputs?

• I am not sure I understand the question, I think you are trying to estimate a long run steady state growth rate for the dividends of a firm? i.e. from year T to infinity, dividends will grow at rate $g_\infty$ where T is a large number. This is what you need to estimate? – Alex C Jun 3 '16 at 4:05
