Net to Gross Calculator Reverse PAYE

Most pay conversations start with a gross figure and work forward to what lands in your account. This calculator runs the opposite direction: tell it the take-home pay you want and it searches for the gross salary that produces it, applying 2026 PAYE, USC and PRSI at every step of the search until the net comes back within a cent of your target.

Why start from net

A few situations put the take-home figure first. A household budget is built around what has to land in the account each month, so working out the gross salary needed to cover it is more useful than starting from a gross figure and hoping. Some roles, particularly informal or part-time arrangements agreed directly between an employer and a worker rather than through a formal recruitment process, are still discussed as a monthly amount in hand rather than an annual gross. Anyone negotiating a contract or comparing a day rate to a salaried role often has a number they need to clear rather than a gross figure they were quoted. In every case the calculation only works one way round if you do it by hand, because PAYE, USC and PRSI each use different bands and there is no single formula to invert. This calculator does the inversion for you.

The same net, a different gross by filing status

Filing status changes how much gross is needed to reach the same net figure, because it changes both the tax credits applied and the width of the standard rate band. A single person aiming for €40,000 a year in take-home pay needs a gross salary of about €50,666 in 2026: the standard rate cut-off is €44,000, so a meaningful part of that salary is taxed at 40% before credits of €4,000 bring the bill down. A married couple assessed on one income aiming for the exact same €40,000 net needs only about €46,085 gross, roughly €4,581 less, because their standard rate band runs to €53,000 and their combined credits are €6,000. Reaching an identical take-home costs a materially different gross salary depending on filing status alone, before age, a medical card or any pension contribution are even considered. That is why the calculator asks for filing status before it searches: leaving it on the wrong setting changes the answer by thousands of euro.

Sanity-checking an offer quoted as take-home

If an employer describes a role by what you would take home rather than what it pays gross, treat that figure the same way you would treat any other claim on an offer: check it. Enter the stated net, your real filing status and age, and see what gross salary it implies. If the same employer, or a rival offer, is quoted in gross terms elsewhere, this lets you compare the two on the same basis rather than guessing. It also catches an assumption that quietly does not apply to you: a net figure worked out for a single person under 40 with no pension is not the net figure you would actually receive if you are married, over 66, or already contributing to a pension, even on the identical gross salary. Run your own numbers through rather than accepting someone else's. For a side-by-side comparison of two roles once you have both gross figures, use the salary comparison calculator.

Why a pension pushes the required gross up, not down

Adding a pension contribution to the calculation changes the answer in the opposite direction from what people often expect. A pension contribution comes off your pay before it reaches your pocket, so to land on the same take-home figure the calculator needs to find a higher gross, not a lower one. Take the same €40,000 net target for a single person: with no pension, the required gross is about €50,666. Ask the same question with a fixed €3,000 a year going into a pension and the required gross rises to about €54,078, an increase of roughly €3,412, more than the €3,000 contribution itself. That happens because pension contributions get income tax relief only: USC and PRSI are still charged on the pension slice of pay, and the extra gross needed to fund the contribution is itself taxed before it reaches the pension. For what relief is actually worth at different contribution levels, see the pension tax relief calculator.
