Interest, tax and fees vary by institution and product. Enter the figures shown in the actual terms.
Tax defaults are reference values for ordinary interest income. The US rate starts at 0% because it depends on your tax bracket. Fees also start at 0% because there is no universal country or product fee; replace them with the actual terms.

Compound calculation
A = P × (1 + (r − f) ÷ n)ⁿᵗ + compounded regular contributionsn is the number of interest applications per year, and t is the investment term in years. r is the annual return and f is the annual fee rate.Tips!
Cautions
- The return is an estimate; actual results can change every year.
- Tax and fees vary by product, account and local rules.
- No universal country tax rate is invented here. Enter a verified rate when you have one.
STEPS
How to use
- Enter the country, starting amount, monthly contribution, rate and term.
- Adjust compounding, contribution frequency, tax, fees and inflation to match the product terms.
- Review the growth table and simple-interest comparison.
