Enter any rupee amount and the year you had it. The calculator uses Pakistan's official Consumer Price Index (CPI) to convert that amount into today's equivalent — i.e. how many rupees you would need now to have the same purchasing power. It also shows how much of the money's value was lost to inflation and how many times more expensive things have become.

It depends on cumulative inflation over the period, which in Pakistan has been steep. Enter Rs 100,000 and select the year above to see the exact figure from CPI data — for many recent 10-year windows, the same basket of goods now costs two to three times as much, meaning cash held over that time lost more than half its real value.

Purchasing power is how much a fixed amount of money can actually buy. When prices rise (inflation), each rupee buys less, so purchasing power falls even though the number of rupees is unchanged. This calculator measures that drop directly using CPI, and illustrates it with real items — litres of petrol, tolas of gold, and US dollars.

It uses Pakistan's Consumer Price Index (CPI), the standard official measure of general price changes, alongside historical petrol, gold, and USD/PKR series for the tangible comparisons. CPI captures average inflation across a basket of goods — your personal experience may be higher or lower depending on what you spend on.

They are related. This tool tells you what a past rupee amount is worth today. To check whether your pay has kept up with inflation — comparing an old salary to your current one after tax — use the Real Salary calculator, which applies the same CPI data to your take-home pay.
