Savings
Compound Interest Calculator
Project future savings growth with a starting balance, one or more monthly contributions, and an expected annual return.
Savings
Savings Goal Calculator
Estimate how long it could take to reach a savings target based on your current balance, recurring contributions, and expected return.
Retirement
Retirement Calculator
Estimate retirement savings growth from your age, retirement age, current balances, monthly contributions, and return rate.
What this calculator shows
Inflation can quietly raise the future price of a goal even when the annual rate seems modest.
It is useful for planning large future expenses, retirement spending, or any long-range savings target that needs a more realistic cost estimate.
How to use it
- 1. Enter the price or budget amount in today's dollars.
- 2. Use the annual inflation rate you want to test.
- 3. Choose the number of years into the future to estimate the inflated cost.
Formula and assumptions
Future cost equals current cost multiplied by (1 + inflation rate) raised to the number of years.
The purchasing-power ratio shows what percentage of today's buying power remains after inflation over the chosen period.
Notes
Actual inflation can vary widely over time, so this tool is best used for scenario planning rather than precise forecasting.
Worked example
A goal that feels manageable in today's dollars can become meaningfully more expensive over a decade or more.

FAQ
FAQ
Why does a small inflation rate matter over long periods?
Because price increases compound over time. Even modest annual inflation can significantly change a cost over ten or twenty years.
FAQ
Is this the same as investment growth?
No. This calculator estimates cost growth, not asset growth, which is why it is often used alongside savings or retirement projections.
