30% Ruling Calculator Netherlands
The 30% ruling can make a new offer look much stronger in the short term. That can be real value, but it can also distort a comparison if you do not check what happens after the ruling effect disappears.
The ruling can improve monthly take-home pay without changing gross salary.
Some offers win now but lose their edge later.
Estimate the impact if the ruling applies, then compare it with the standard tax case.
Why it matters
If one role qualifies for the 30% ruling and the other does not, the short-term monthly gap may look much bigger than the underlying gross salary gap. That is why a simple gross comparison is often misleading.
A good 30% ruling calculator should therefore show three things clearly: current net per month, current net per year, and estimated net income after the ruling no longer applies.
Decision logic
See how much the new offer changes monthly cash flow under the scenario you are testing.
A modest monthly gap can still add up to a meaningful annual difference.
If eligibility is uncertain, test both cases so you understand the upside only if the ruling is actually granted.
If the ranking changes later, you should treat the short-term win more cautiously.
Pension, bonus, growth, role quality, commute, and flexibility may matter more when the salary gap is small.
Reality check
Use a calculator to understand direction and magnitude. Use your employer, payroll provider, or advisor to confirm the final implementation.
