Why this site exists
Try to find out what a two bedroom flat in Yaba costs this year. Or what a mid level accountant in Abuja is actually being offered. Or what your take home pay will be under the tax rules that came into force in January 2026. You will find opinions, outdated figures and a great many calculators built for somewhere else.
That last problem is the one that started this. Search for a CGPA calculator and most of what comes back assumes a 4.0 grading scale, because that is what American universities use. Plenty of Nigerian universities run on 5.0, and a few on 7.0. Put your grades into the wrong one and you get a number that looks authoritative and is simply wrong.
The same pattern repeats everywhere. Take home pay calculators that still apply the Consolidated Relief Allowance, which the Nigeria Tax Act 2025 abolished. Rent affordability tools that assume you pay monthly, when your landlord wants a year or two in advance. Household budget tools that have never heard of a generator. Each of them produces a confident number, and each of them is wrong in a way you cannot see from the output.
A wrong number you trust is worse than no number at all, because you act on it. That is the gap this site tries to close.
What we actually do
Three things.
The calculators. There are 38 of them, covering education, money, business, everyday costs, technology and general utilities. Every one starts from how the thing actually works here, then does the arithmetic. Each page sets out the formula, works through a real example, lists the mistakes people make, and answers the questions that actually come up. That last part matters: a calculator you cannot check is a machine asking for trust it has not earned. Ours are built to be checked.
The reader data. We collect what people actually pay for rent, salaries, school fees, transport and food, anonymously and with no account needed, and publish the medians by state and city. It is the only way we know to get current, local, real figures into the open, because nobody else publishes them.
The guides. The blog covers careers, scholarships, remote work, study abroad, school fees and portal instructions at a length a calculator page does not allow.
Built for here, not adapted
Grading scales of 5.0, 4.0 and 7.0. The 2026 tax bands with the abolished relief correctly removed. Rent paid annually in advance. Generator fuel sitting alongside the electricity bill. These are not footnotes we added later, they are how the tools were designed.
Nothing leaves your browser
Every calculation runs on your own device in JavaScript. Your salary, your grades, your rent: none of it reaches our server, our database or us. That is also why there is no sign up. There is nothing to attach an account to.
The method is always shown
Every tool explains what it is doing and why. If you disagree with an assumption, you can see it and adjust for it. We would rather you understood the calculation than trusted the output.
We say what we do not know
Where a figure is an estimate, we say so. Where reader data is thin, we show the entry count so you can weigh it. Where something changes often, we say when it was last checked.
How we check our figures
Anything with a rule behind it gets traced to the rule. The tax bands in the Salary After Tax Calculator come from the Nigeria Tax Act 2025 as it took effect on 1 January 2026, including the removal of the Consolidated Relief Allowance and the introduction of rent relief at the lower of twenty per cent of annual rent or five hundred thousand naira. VAT is at the standard 7.5 per cent. Degree classification bands follow the thresholds Nigerian universities publish for each scale.
Anything that varies gets treated as a variable rather than baked in. Electricity tariffs differ by band and by distribution company, so the tool asks for your rate instead of assuming one. Fuel prices move, so you enter the current pump price. Bank interest, school fees and rent all work the same way.
Every tool page carries the month it was last reviewed. When a rule changes, the tool and the surrounding text change together. If you find something wrong or out of date, tell us and we will correct it. Corrections are welcome and we are not precious about them.
The reader data, and why it matters
Information asymmetry is expensive, and it runs in one direction. A landlord knows what every flat on the street rents for. An employer knows what everyone on the team earns. The person on the other side of that conversation usually knows only their own number, and negotiates accordingly.
Our data section exists to narrow that gap slightly. Readers report what they pay. We review every submission, then publish medians by state and city alongside the entry count and range, so you can tell a real signal from two people's anecdotes.
No account is needed and no personal information is collected. We never ask for a name, an email address or an employer. A submission is a location, a description, an amount and a date. Nothing about it can be traced back to anyone.
It is self reported and we say so plainly. It is not an audited statistic and our contributors are not a representative sample of Nigeria. But a hundred people saying what they actually paid last month is considerably more useful than nothing, which is the current alternative.
How the site is funded
Advertising, and nothing else. There is no subscription, no paywall and no premium tier. Every calculator, every data set and every article is free to everyone, and we intend to keep it that way.
We do not sell your data, because we do not have any to sell. The calculators never transmit what you type. The data submissions carry nothing identifying. There is no user account system.
Where we link to a third party, the link is there because it is genuinely useful. If a link is ever commercial, it will say so where it appears. We do not accept payment to recommend a product, an institution or a service inside our editorial content, and we do not write reviews in exchange for anything.
What we are not
We are not financial advisers, lawyers, tax practitioners, accountants or academic registrars, and nothing here is professional advice. The calculators do arithmetic on figures you supply. They do not know your circumstances, and they cannot account for the exception that applies to your case.
We are not affiliated with any university, examination body, government agency, bank or employer mentioned on the site. Where we explain how an institution's process works, that explanation is our reading of published information and not an official statement. Always confirm anything consequential directly with the institution concerned. Our disclaimer sets this out in full.
Where to start
If you are here for a specific number, the tools index lists everything by category, and the search covers tools, data and articles together.
If you want to know what things cost, the data section has rent, salaries, school fees, transport and food by state.
If you are reading rather than calculating, start with careers, scholarships, remote jobs, school fees or the portal guides.
And if the thing you need does not exist yet, say so. A good number of the tools on this site were built because somebody wrote in and asked.
Contact. Corrections, suggestions, partnership enquiries and complaints all go to the same place: our contact page. We read everything, and we answer most things within a few working days.
