Retirement is arguably the most important aspect of one’s financial planning. Investing in a pension plan is a vital part of saving for your future. Looking at your requirements, I would suggest you to get life insurance quotes from various insurance providers online and accordingly select a retirement plan which offers you good savings and features.
I have purchased a retirement plan from Bajaj Allianz called Pension Guarantee plan. I am quite satisfied with the offerings like 15 day free look period and tax benefits under section 80C and many more. I would recommend you go for the same retirement plan.
