What the comparison means
The comparison changes only annual income, keeping every other example input fixed. This isolates that input's effect on the primary result. It does not predict future outcomes.
Rates, fees, eligibility, local tax rules and provider rounding can change the final amount. Reference tax and exchange-rate data may be outdated; verify the official source before deciding.
