Purchasing Power Explained: What Inflation Does to Money

Purchasing power describes what money can buy

Purchasing power is the value represented by an amount of money in terms of goods and services. When prices rise, the same nominal amount may cover less than it did before.

The nominal ₹1,00,000 does not change merely because the calculator is switched to purchasing-power mode. The calculator estimates what that amount may represent later under the entered inflation assumption.

Worked example: the future purchasing power of ₹1,00,000

With ₹1,00,000, an illustrative constant inflation assumption of 6% and a 10-year period, purchasing-power mode returns:

The nominal amount and its represented value are different concepts

The ₹55,839.48 result is not a future bank-account balance. It does not say that ₹44,160.52 physically disappears. It expresses the modeled erosion in what the original ₹1,00,000 may represent after 10 years.

It is also not an investment loss or portfolio return. The engine receives no investment, market value, interest rate, contribution or fee information.

Purchasing power is the inverse view of future cost

Future-cost mode increases a present cost by the compounded inflation factor. Purchasing-power mode divides the nominal amount by that same factor. This is why positive inflation moves the two displayed values in opposite directions.

Compare that interpretation with How Inflation Changes Future Cost.

The represented value still depends on the assumption

Actual inflation varies, and a person's spending mix can differ from a general price index. The estimated purchasing power therefore remains a scenario based on one constant entered rate.
