"Finally, a calculator that handles the 2027 tax rule changes. The salary cliff visualization made me realize I need to negotiate a raise before my ruling ends."

Maarten V.

Senior Engineer, Amsterdam

"The Job Switch simulator saved me €8,000. My employer's VSO offer was below statutory minimum—I didn't even know that was a thing."

Ana K.

Product Manager, Rotterdam

"As someone who sends money home to the Philippines, the Wealth Mountain in PHP is incredibly motivating. I can actually see my progress toward my goal. And the fact that my salary data never leaves my phone? That's huge."
