Frequently Asked Questions
Is Pay44 more accurate than ADP?
Pay44 calculates federal and state income tax from the federal and state tax brackets for your filing status. Accuracy differences usually come from what you enter: deductions, benefits, and local taxes. Neither should be relied upon for exact calculations; always verify with your actual pay stub.
Can I use the ADP calculator without an employer account?
Yes. ADP's web-based salary and hourly calculators are free and don't require an account. The ADP Mobile Solutions app, however, requires your employer to use ADP payroll services.
Does ADP's calculator work offline?
No. ADP's web calculators require an internet connection. Pay44 works offline once installed, which is useful for calculating on the go or in areas with poor connectivity.
Which is better for comparing job offers?
Pay44. It saves multiple calculations, and with a Pro subscription it compares them side-by-side in a normalized table, including hourly positions against salaried positions on equal footing. ADP doesn't save calculations or offer comparison features.
Does Pay44 support local taxes like NYC or Philadelphia?
No. Pay44 currently supports federal and state taxes only. If you work in a city with local income tax, use ADP's web calculator for a rough estimate that includes local taxes, then adjust manually in Pay44.
Why would I use ADP if Pay44 has more features?
If your employer uses ADP payroll, the ADP Mobile app gives you access to your actual pay stubs, W-2s, and benefits info. That's real data from your employer's payroll system, not estimates. For viewing what you've actually been paid, ADP is unbeatable.
