Turbotax has a calculator but it is set to 2024 numbers, so it will be in the ballpark but not exact.

Also, remember that brackets don't change your whole tax, just the top slice. For example, if most of your income is in the 12% bracket and you were to go into the 22% bracket by $1000, only that last $1000 is taxed at 22%, the rest is still taxed at 10% or 12%.
