How many years does teak (sagwan) take to give good timber and what return per tree?

Teak (sagwan) is a premium hardwood and a classic long term timber investment. With good site quality and management you get thinnings from around 8 to 12 years and good girth final harvest timber around 20 to 30 years, with the best logs taking even longer. It is genuinely a generational crop on poorer sites. The value depends heavily on girth, straightness, heartwood and the timber rate at sale, so per tree income is a wide range, not a fixed lakhs figure, and the big numbers usually come only from very old, large girth trees. Teak grows best on well drained soils and does poorly in waterlogged land. Use good quality clonal or improved seedlings. Plant, prune for a clean bole, thin on schedule, and treat it as a slow appreciating asset. Check your state transit pass and felling rules for teak, since even private timber needs transit documentation in most states.
