The Definitive Guide to the Nigerian Monthly Budget Planner & Cost of Living Calculator
Quick answer: The TurnetFinance Monthly Budget Planner builds a full monthly spending plan from your take-home pay. It prices your rent and transport using city data for Lagos, Abuja or Port Harcourt, sets aside savings, and splits the rest across food, utilities, data, health, clothing and education in the same proportions Nigerian households actually spend. It then shows your savings rate, any deficit and how your plan compares with benchmarks.
What the Budget Planner Does and Why It Matters
To build a workable budget, you must know what you take home, what your city charges for rent and transport, and what is left for everything else. This planner calculates those figures from the income and housing details you enter. It is built for salary earners, freelancers and side-hustlers, young professionals, couples and families who want a plan grounded in real Nigerian prices rather than a foreign formula.
Budgeting matters because prices are moving fast. The National Bureau of Statistics (NBS) reported headline inflation of 15.39% in August 2026, with food inflation at 19.57% and core inflation at 13.29%. Transport has risen even faster: the average city bus fare was ₦1,431 per drop in May 2026, up 38.6% from a year earlier.
Why the planner no longer uses the 50/30/20 rule
The 50/30/20 rule allocates 50% of income to needs, 30% to wants and 20% to savings. It is a useful habit-builder, but Nigerian data shows it cannot work as a literal rule for most urban renters. Take a ₦250,000 income in Lagos with a self-contain at the average asking rent (₦166,667 a month) and a daily commute at the NBS Lagos fare (₦76,623 a month). Rent and transport alone come to ₦243,290, which is 97% of income and nearly double the 50% the rule allows for all needs. So the planner uses a Reality Plan built on actual city costs, and keeps the rule’s best idea: pay yourself first.
The three budget methods
Reality Plan (default) prices rent and transport from your city, sets aside 10% for savings, and splits the remainder across spending categories. Savings-first 20% works the same way but moves 20% to savings before anything else. Custom lets you set your own percentages for rent, food, transport, data and savings, with the rest placed in a buffer.
How your numbers are calculated
- Take-home pay is income after tax and pension. Always enter this, not gross salary.
- Fixed payments (loans, family support, car fuel and upkeep) are numbers you type in, so the planner never guesses them.
- Spending weights come from the NBS rebased Consumer Price Index (2024 base): food 53% (40.1% food plus 12.9% eating out), utilities and household fuel 8.4%, health 6.1%, education 6.2%, clothing 5.0% and data and communication 3.3%.
- Per adult-equivalent income divides household income by 1.0 for a single adult, 1.5 for a couple and 2.1 for a family, using the OECD-modified equivalence scale.
A worked example: Abuja, ₦250,000 a month
Choose Abuja, a self-contain at the average asking rent, a daily commute and the Reality Plan:
| Category | How it is set | Monthly amount |
|---|---|---|
| Rent | ₦1.5M a year ÷ 12 | ₦125,000 |
| Transport | ₦1,431.25 × 2 × 22 | ₦62,975 |
| Savings | 10% of income | ₦25,000 |
| Buffer | 5% of the remainder | ₦1,851 |
| Food & eating out | NBS weight share | ₦22,734 |
| Utilities & fuel | NBS weight share | ₦3,603 |
| Health | NBS weight share | ₦2,617 |
| Education | NBS weight share | ₦2,659 |
| Clothing | NBS weight share | ₦2,145 |
| Data & airtime | NBS weight share | ₦1,416 |
The squeeze is visible: with rent and transport priced realistically, only about ₦22,700 is left for food for the month. Switch to Port Harcourt at ₦150,000 and the same method leaves about ₦20,100 for food, because rent and fares are lower. That is the point of pricing by city.
Nigerian Cost of Living: Rent, Transport, Tax and Savings
Rent by city
Rent in Nigeria is quoted per year. On Nigeria Property Centre in September 2026 the average asking rent was about ₦2.0M a year for a Lagos self-contain and ₦3.5M for a Lagos 1-bedroom; ₦1.5M for an Abuja self-contain and ₦3.5M for an Abuja 1-bedroom; and ₦1.5M for a Port Harcourt 1-bedroom. These are asking rents on a listings site, pulled upward by premium areas, and they exclude agency, legal and caution fees. If you live in a lower-cost area, share a home or pay less, type your actual rent.
Transport
The NBS Transport Fare Watch reported average intra-city bus fares per drop of ₦1,741 in Lagos and ₦1,188 in Rivers State in May 2026, against a national average of ₦1,431. Because we did not find a published FCT figure, Abuja uses the national average.
Where costs are not city-specific
Food, utilities, data and health use national NBS spending proportions. The sources we checked do not publish verified food or utility price levels for each city, so the planner does not pretend otherwise.
Tax and take-home pay
The Nigeria Tax Act 2025, effective 1 January 2026, taxes the first ₦800,000 of annual taxable income at 0%, with progressive rates starting at 15% above it. Rent relief replaced the Consolidated Relief Allowance: you can deduct 20% of annual rent, up to ₦500,000, if you declare your actual rent. The national minimum wage is ₦70,000 a month. The Nigeria Revenue Service (NRS, formerly FIRS) and state revenue services administer these rules, so confirm your deductions with your employer.
Interest rates and savings
The Central Bank of Nigeria (CBN) cut the Monetary Policy Rate to 23% on 22 September 2026. Rates on savings and loans adjust slowly, so compare what your bank or app actually offers. Your main options are ajo and esusu groups (trust-based, no deposit insurance), cooperative societies (check the bye-laws and audits), savings apps such as PiggyVest and Cowrywise (confirm the licensed partner bank or SEC registration), and CBN-licensed banks and microfinance banks whose deposits NDIC insures up to the statutory limit.
What to Do After You Build Your Budget: A Practical Checklist
- Check your rent and transport share first. If they exceed 60% of income, your plan has little room, so test a cheaper area, a shared place or fewer commute days.
- Replace averages with your real numbers. Type your actual rent and use the Custom method once you know your real spending.
- Fix any deficit immediately. The planner shows how far costs exceed income. Reduce rent or commuting before anything else, because both are fixed for months at a time.
- Set aside the rent lump sum monthly. Divide annual rent and fees by 12 and save it so renewal day does not become a crisis.
- Automate savings on salary day. Move the planner’s savings figure before you spend.
- Build an emergency fund. The planner shows a target of three months of spending.
- Claim rent relief. Declare your actual rent to use the 20% relief, up to ₦500,000.
- Keep loan repayments visible. Enter them as fixed payments and use the Loan Calculator to check their true cost.
- Rebuild monthly. Update income, rent and fares and compare the new plan with last month’s.
If the plan still shows a deficit after these changes, the gap is income, not discipline. Add side income in the planner to see how much closes it.

Frequently Asked Questions About Budgeting in Nigeria
How much of my salary should go on rent in Nigeria?
A common international benchmark is 30% of take-home pay, but Nigerian city rents often exceed it. In September 2026 the average Lagos self-contain asking rent was about ₦166,667 a month and the average Lagos 1-bedroom about ₦291,667.
Those are asking rents on a listings site and run high because of premium areas, so enter your actual rent in the planner. Under the Nigeria Tax Act 2025 you may also claim rent relief of 20% of annual rent, capped at ₦500,000, when you declare your rent.
Does the 50/30/20 rule work in Nigeria?
Not literally. The rule assumes needs take 50% of income, but at average city asking rents and NBS bus fares, rent and commuting alone can use 97% of a ₦250,000 income in Lagos.
That is why the planner uses a Reality Plan: it prices rent and transport from your city, saves a set share, and splits the rest using NBS household spending weights. The rule's real lesson, paying yourself first, still applies.
How much should I save monthly on a ₦100,000 salary?
The planner's default target is 10%, which is ₦10,000 a month, rising to 20% (₦20,000) on the Savings-first method. These are planning conventions rather than statistics, and savings are capped at half of what remains after rent, transport and fixed payments.
If your rent and commute leave little, a smaller steady amount still builds the habit. At ₦10,000 a month you reach ₦120,000 in a year.
Are ajo, esusu and savings apps like PiggyVest and Cowrywise safe?
Safety depends on who holds your money and how it is regulated. Informal ajo or esusu groups run on trust and carry no deposit insurance, while regulated platforms should disclose their licensed partner bank or SEC registration.
Before depositing, confirm the platform's regulatory status, read the withdrawal terms and check whether your money sits with a CBN-licensed bank or microfinance bank covered by NDIC deposit insurance.
How do I budget when prices keep rising?
Rebuild your budget every month and protect your savings rate first. NBS reported headline inflation of 15.39% and food inflation of 19.57% for August 2026, and the average city bus fare was up 38.6% in May 2026 compared with a year earlier.
Track what you actually spend on food and transport, then switch to the Custom method with your real numbers.
Do I pay income tax on a small salary in Nigeria?
Not on the first ₦800,000 of annual taxable income. Under the Nigeria Tax Act 2025, effective 1 January 2026, that band is taxed at 0%, so minimum wage earners are exempt from PAYE.
Income above the threshold is taxed progressively from 15%. Enter your take-home pay in the planner and confirm your exact deductions with your employer or a tax professional.
Disclaimer: This planner is an informational tool. TurnetFinance does not provide personalised financial, tax or investment advice.
