Question 1

Where does the official CPI number come from?

Accepted Answer

The benchmark is MOSPI CPI Combined annual inflation from the same IndiaGraphs series as the India inflation rate dataset. The latest completed financial year on that series is used.

Question 2

Is this a live monthly CPI quote?

Accepted Answer

No. Headline CPI here is the MOSPI financial-year average for CPI Combined, not a live tick. Personal inflation is the exact percentage change in the monthly spends you enter.

Question 3

How is personal inflation calculated?

Accepted Answer

Personal inflation = ((Current monthly total − Previous monthly total) / Previous monthly total) × 100. Extra monthly burden is current total minus previous total grown at the MOSPI CPI rate.

Question 4

Why does my inflation feel higher than official CPI?

Accepted Answer

Headline CPI is a national average basket. If more of your spending sits in rent, education, healthcare or lifestyle, your personal rate can run well above the MOSPI print.

Question 5

How accurate is this calculator?

Accepted Answer

The CPI benchmark is the published MOSPI figure on the IndiaGraphs inflation dataset. Your personal rate is exact arithmetic on the spends you type, including extra quantities, not only price rises. It is a planning tool, not a substitute for MOSPI’s monthly press release or financial advice.
