Inflation-Adjusted Goal Calculator
What today's savings goal looks like in future units after inflation.
Uprate a savings goal for inflation — see what today's target amount needs to be in future units after a chosen inflation rate.
What this tool does
This calculator translates a savings goal stated in today's currency into the amount you would need in the future to hold the same purchasing power. Inflation erodes the real value of money over time, so a goal of 100 in your currency today may require 110 or more in future years to buy the same goods and services. The tool compounds your stated goal at the expected inflation rate across your chosen timeframe to show this adjusted figure. The result is most sensitive to the inflation rate you enter and the number of years involved—longer timeframes and higher inflation rates produce larger adjustments. For example, someone saving for a home purchase or education expense five years ahead would see how inflation might change their target amount. The calculation assumes a consistent annual inflation rate and doesn't account for variations in price changes across different categories of spending or other economic shifts that might affect real costs.
Quick answer: with the default values, the result is $180,611.12 (Future-Pound Goal). Adjust the values below for your own figures.

A 100,000 goal today at 3% inflation over 20 years needs to be 180,611 in future units to preserve the same real purchasing power. Planning in today's units understates the target; this tool translates to the nominal number you'll actually need.
How to use it
Enter today's goal (the purchasing power you want), expected annual inflation, and years until the money is needed. The tool returns the nominal pound amount required in the future.
Why this matters for long goals
Education funds, retirement pots, and house deposits often have horizons of 10+ years. Planning in today's units works short-term but fails long-term. A 3% inflation assumption over 25 years means the target needs to roughly double in nominal terms to maintain real value.
A worked example
With the defaults: today's goal of 100,000, inflation rate of 3%, years of 20 years. The tool returns 180,611.12.
What moves the number most
The result responds to Today's Goal, Inflation Rate, and Years.
The formula behind this
Today's goal compounded at expected inflation for the given years. Uses annual compounding consistent with how inflation is typically reported.
A goal in today's money is a standard, not an amount
A goal expressed in today's money describes a standard of living, not an amount. The calculator inflates it forward so the target represents the same purchasing power at the end of the period. At the defaults, 100,000 at 3% inflation over twenty years becomes about 180,600, meaning a plan aimed at the round number would land roughly 45% short in real terms.
Why the rate you enter does all the work
The inflation rate entered does the entire work, and general inflation is only an approximation of any particular goal. Education, healthcare, and construction costs have historically moved at different rates from headline consumer prices in many countries, so a goal concentrated in one of those areas may need a rate above the general figure. The calculation is also a straight compounding of a single rate, so it smooths over periods where inflation runs well above or below its average.
A £100,000 goal will need to grow to $180,611.12 in 20 years at 3% inflation.

Sources & Methodology
Methodology
This calculator computes the future nominal value of a savings goal by applying compound inflation over a specified time period. It takes your stated goal in today's currency units and multiplies it by the inflation factor (1 + inflation rate) raised to the number of years. The model assumes a constant annual inflation rate throughout the period and applies annual compounding, consistent with standard inflation reporting conventions. The result shows what your goal would need to equal in future currency units to maintain the same purchasing power. The calculator does not account for variations in inflation across years, changes in savings targets, or the actual timing of when funds are deployed.
