Estimates, not guarantees
Results describe the scenario you enter under the stated assumptions. They are not guaranteed returns, personal financial, investment, tax or legal advice, or a recommendation of a financial product. Check inputs, units and assumptions before relying on an answer.
Check your account’s terms
The calculator uses a constant, non-negative annual rate and excludes fees, tax and inflation. Investment values can fall; this calculator does not model market losses.
The calculator uses a 365-day model year, 7-day weeks and 12 equal months for daily, weekly and monthly compounding. Rates, deposit timing, rounding and bank crediting rules can make actual interest differ.
Amounts are rounded for display after calculation. Currency changes formatting without exchange conversion; region does not select tax rules or account conventions.
Privacy & corrections
With JavaScript, calculation runs in browser memory. Without it, values are sent to Cloudflare for temporary calculation. Values stay out of URLs; server results are private, not cached or indexed. See the calculator’s privacy details.
