What is Post Office MIS?
The Post Office Monthly Income Scheme (POMIS) is a government-backed savings scheme that pays a fixed monthly interest — currently 7.4% per annum — on your deposit for 5 years. The interest is paid out monthly (not compounded), and the principal is returned at maturity. A single account can hold up to ₹9 lakh and a joint account up to ₹15 lakh.
Formula
POMIS pays simple interest monthly:
Monthly interest = P × r / (100 × 12) Total interest (5 yrs) = monthly × 60 r = annual rate (currently 7.4%) P = principal (max ₹9L single / ₹15L joint) Principal is returned at maturity; interest is not compounded.
