base64_convert

Encode text to Base64, or decode Base64 back to text. UTF-8 throughout, so accented text, emoji, Arabic, Devanagari and CJK survive the round trip — the naive btoa/atob version does not. Interactive version: https://zaleso.com/base64

ng_gross_for_take_home

Work backwards from a target take-home to the gross salary that produces it, under the Nigeria Tax Act 2025 (2026 tax year). This is the question employers and contractors actually ask — "what must I pay for them to clear ₦500,000 a month" — and it cannot be answered by applying a rate, because PAYE is banded. Returns the required gross with the full band-by-band working and the statutory source. Informational only — verify with the tax authority. Interactive version: https://zaleso.com/ng/net-salary

read-only

Argument	Type	Description
period	string	Whether takeHome is monthly or annual. Default monthly.
takeHome*	number	Target take-home (net) pay in naira, after PAYE and deductions.
includeNhf	boolean	Deduct the 2.5% National Housing Fund contribution — voluntary for private-sector employees since 2023. Default false.
includePension	boolean	Deduct the 8% employee pension contribution (PRA 2014). Default true.

ng_vat_calculate

usd_ngn_convert

Convert between Nigerian naira and US dollars, pounds, euros and other currencies at the Central Bank of Nigeria's official rate — the latest, or the rate that applied on a past date.

to	string	Only when from is NGN: the currency to convert to. Default USD.
