Post Office Monthly Income Scheme: Securing a reliable monthly interest stream

Shila retired with a lump sum gratuity and wanted to generate a steady monthly income. She opened a joint Post Office MIS account with her husband, depositing the maximum limit of ₹15 Lakhs.

At the current 7.4% p.a. interest rate, she receives a guaranteed monthly payout of ₹9,250 directly to her savings account. After the 5-year lock-in period, her original ₹15 Lakhs deposit will be returned in full.

The Post Office MIS offers a highly safe monthly income stream for risk-averse investors, with limits of ₹9 Lakhs for single and ₹15 Lakhs for joint accounts.

This is an ideal choice for retirees looking to cover monthly living expenses without risking their principal.
