Net-to-Gross Salary Calculator — What Gross Should You Negotiate in Nigeria?

Start with the net salary you want

Salary negotiations in Nigeria usually happen in net terms — "I want five hundred thousand in my account" — while offer letters are written in gross. Under the Nigeria Tax Act 2026, converting between the two is not a flat percentage: PAYE is progressive, pension and NHF move with the package, and rent relief is capped. This calculator solves the reverse problem exactly — enter the net you want, and it finds the gross that produces it, to the kobo.

It works from four inputs:

• The net pay you want, monthly or annual.
• Your pension assumption — the statutory employee contribution of 8% by default.
• Whether you have opted into NHF (2.5% of basic).
• Your annual rent, if you will claim rent relief.

What the calculator returns

• The required gross salary — the number the offer letter must say.
• The full deduction breakdown at that gross: PAYE band by band, pension, and NHF where opted in.
• Confirmation that the resulting net matches your target to the kobo.
• What that gross costs the employer in total — useful to know what you are really asking for; the employer total cost of employment calculator shows the same figure from the employer's side.

Why net-to-gross is not a simple reverse percentage

Progressive bands mean marginal ≠ effective rate

Adding ₦100,000 to a gross salary does not add a fixed fraction to net pay. Which band the increase lands in decides the split: the same raise is taxed at 15% for one employee and 21% for another. That is how PAYE bands work under the NTA 2026 — the tax on the last naira is not the tax on the average naira, so the conversion has to be solved, not multiplied.

Reliefs move with the salary

Pension and NHF scale with the package, but rent relief is capped at ₦500,000 no matter how large the salary grows. The gap between gross and net therefore changes shape as the number grows — at low salaries reliefs cover proportionally more; at high salaries the capped relief fades into rounding.

Worked negotiation example

A candidate wants ₦500,000.00 a month in their account. Assume pension at the statutory 8% computed on full gross (the conservative default when the basic/housing/transport split is not yet fixed), no NHF opt-in, and no rent relief. Solving for the gross:

The candidate needs a gross of ₦639,581.13 to land exactly ₦500,000.00 net. If the employer counters ₦50,000.00 a month lower in gross, the candidate's net falls to ₦462,280.01 — the counter costs them ₦37,719.99 a month in take-home, not ₦50,000, because part of the cut would have gone to PAYE and pension anyway. Two numbers, one table: that is the whole negotiation, made explicit.

How HR teams use this

• Sanity-check offers before they go out — the gross on the letter provably produces the net that was promised in the room.
• Answer "net" demands from candidates instantly and defensibly, with the band-by-band arithmetic to show for it.
• Keep internal bands fair when different employees negotiated in different terms — some in net, some in gross — by normalising everyone to the same basis.

For the forward direction — gross in, net out — use the Nigeria PAYE & net salary calculator. And when the offers become payroll, KoboHR is payroll software built for the NTA 2026: the same arithmetic, run for the whole company every month.

Net-to-gross FAQs

How do I calculate gross salary from net pay under the NTA 2026?

There is no flat multiplier: PAYE is progressive and reliefs scale with the package, so the gross must be solved for. The calculator finds the gross salary whose PAYE, pension, and NHF deductions leave exactly the net you entered.

Why does the employer's cost exceed my gross salary?

Employers pay statutory contributions on top of gross: pension at 10% of basic, housing and transport, NSITF at 1% of payroll, an ITF accrual, and NHIA health contributions. None of these appear on the payslip, but they are part of what a hire costs.
