Just made 40K contribution in 10K x4
Activated 2% & 10x rider for 199+299 = 498₹
For each 10K txn - 112.32₹ charges were added by NPS (including all NPS, CC, convenience charges)
Hence paid total 40,449.28 (10,112.32 x4)
Calculating slab offer of 10k x4 = 4000RP (800₹)
Calculating 2% of 40,449 = 808₹
Calculating 10x of 40,449 = 4044RP (808₹)
Total value - 2418₹
Now deducting 498 (rider charges) - 450 (NPS charges) - 118 (Redemption fees) = 1351₹
Around 3.3% for me.
Rider benefits last 90 days from date of activation. So it will depend on the amount you will spend.
