Your assumptions

Model a future cost

Enter an amount in today's money, then choose the time horizon and annual inflation assumption.

Amount today

₹

This can be a monthly budget, annual expense, tuition fee, home renovation cost or any other amount. Amount type

This changes the wording only; the inflation mathematics is the same. Years into the future

years

Choose the number of years between today and the future date you want to model. Annual inflation assumption

Enter any rate from 0% to 30%, including decimals such as 4.5% or 5.5%. Carrowmont does not silently substitute a live or country-specific forecast.

Country vs inflation: country selection controls formatting and default currency. It does not automatically change your inflation rate, taxes, pension rules or financial assumptions.

Want current U.S. CPI context? See the Carrowmont Inflation & Purchasing-Power Monitor. The Research reading is context only; this calculator continues to use the inflation assumption you enter.

Future equivalent

To buy what ₹100,000 buys today, you may need

₹265,330

after 20 years at 5.0% annual inflation

Total price increase165%

Inflation multiplier2.65×

Same nominal amount's future buying power38%

Equivalent purchasing power of the same nominal amount₹37,689

About 62% less purchasing power

If prices rise at the entered rate, keeping the same nominal budget would buy less than it does today.

How to use this tool

Three ideas to keep separate

Today's money

What your current amount can buy now. This is the easiest reference point when thinking about lifestyle or purchasing power.

Future nominal money

The larger number of currency units you may need later if prices rise. It is not automatically “more wealth”; part of the increase may simply reflect inflation.

Country & currency

Carrowmont can format the same calculation for different regions and currencies. Changing currency does not perform an exchange-rate conversion.
