Inflation calculator

See what inflation quietly changes.

Estimate how much you may need in the future to match today’s purchasing power.

How it works

Nominal money and real purchasing power tell different stories.

The calculator compounds a constant inflation rate over the selected period. It shows both the future cost of matching today’s purchasing power and what the same nominal amount may feel like in today’s money.

Formula

Future cost = today’s cost × (1 + inflation rate)ʸᵉᵃʳˢ

The calculation uses the values you enter and assumes the selected rates remain constant throughout the scenario.

Worked example

At 2.5% average inflation, something costing $50,000 today would cost about $82,000 in 20 years. This is a constant-rate scenario, not a forecast.

Inflation compounds too

A modest annual rate can create a meaningful difference across a decade or more.

Personal inflation varies

Housing, healthcare, education and lifestyle costs may move differently from a headline index.

Measure real progress

Growing net worth is more meaningful when the increase exceeds the loss of purchasing power.

Frequently asked questions

How to interpret the result

Is the result a prediction?

No. It is a transparent scenario based on your inputs. Returns, inflation, spending and personal circumstances can all develop differently.

How often should I update the calculation?

After a major financial change and at least a few times a year. For long-term decisions, consistent updates matter more than a one-time perfect estimate.

Does this calculator store my numbers?

No. The calculation runs in your browser. If you want history and a recurring monthly view, you can manage your figures inside Hugo.
