30% slab: Rs 1.5L investment → Rs 45,000 tax saved (+ Rs 1,800 cess) = Rs 46,800
Effective return: At 30% slab — Rs 1.5L investment + Rs 46,800 tax saving + 6.5% interest = excellent return

⚠️ Tax Saving FD vs ELSS: ELSS mutual funds also qualify for 80C but have only 3-year lock-in vs 5-year for FD. ELSS historically gives 12-15% returns vs 6-7% for FD. If your goal is maximum tax saving + growth, ELSS is better. If you want guaranteed returns with zero risk, choose tax-saving FD.
