Knowing how to calculate estate service charge in Nigeria starts with one simple principle: work out what it will realistically cost to operate the estate, then decide how that cost should be shared among the properties responsible for paying it.
The wrong approach is to choose a convenient figure such as N200,000 per house and hope the money lasts for the year.
A proper service charge should come from an operating budget covering security, power, water, waste, maintenance, cleaning, management and other shared services the estate actually provides.
What expenses should be included in an estate service charge?
Start by listing every recurring cost required to operate the common areas and shared services.
Depending on the estate, this may include:
- security guards;
- security supervision;
- gate operations;
- waste collection;
- common-area electricity;
- generator diesel;
- generator maintenance;
- borehole operation;
- water treatment;
- pump maintenance;
- cleaning;
- landscaping;
- drainage cleaning;
- streetlight maintenance;
- access-control maintenance;
- CCTV maintenance;
- minor road repairs;
- facility management;
- accounting;
- administrative expenses;
- insurance where applicable;
- and other shared operating costs.
Do not copy another estate's budget.
A 50-unit estate with one gate and no generator will have a very different cost structure from a 500-unit community with several entrances, central water, recreational facilities and extensive security infrastructure.
Use actual information wherever possible.
Ask current vendors for quotations.
Review previous electricity and diesel usage.
Check maintenance history.
Confirm staff costs.
Look at contracts that will renew during the year.
The purpose is to estimate what the estate will genuinely need rather than creating an attractive figure that later results in repeated emergency levies.
RICS service-charge guidance recommends using professional judgement and realistic expected expenditure when preparing an annual budget and specifically warns against deliberately underestimating future costs. Its 2026 residential code also recommends that initial service-charge budgets for new developments reflect the likely ongoing cost of the property rather than an artificially low introductory amount. (RICS)
For a new development, also read the service charge setup guide.
What is the basic service charge formula?
A simple starting formula is:
Annual operating expenses + planned reserves or contingency - other estate income or credits = amount residents need to fund
The amount to recover is then allocated among the properties according to the estate's approved sharing formula.
For example, suppose the estimated annual operating costs are:
- Security: N18,000,000
- Waste collection: N4,800,000
- Water operations: N6,000,000
- Common power and generator costs: N9,600,000
- Maintenance: N6,000,000
- Management and administration: N4,800,000
- Cleaning and landscaping: N3,600,000
- Contingency: N3,200,000
Total estimated annual cost:
N56,000,000
Suppose the estate also expects N2,000,000 of legitimate income or credits that can be applied to operations.
Amount residents need to fund:
N56,000,000 - N2,000,000 = N54,000,000
If the estate contains 100 equally assessed homes:
N54,000,000 divided by 100 = N540,000 per home per year
Monthly equivalent:
N540,000 divided by 12 = N45,000 per month
These figures are only an example. They are not recommended market prices.
The important part is the method.
Your service charge should be built from your estate's actual expected costs.
Should every house pay the same service charge?
Not necessarily.
Equal billing is easy, but it is only appropriate where the estate's governing documents and agreed allocation structure support it.
An estate containing similar houses may decide to divide common costs equally.
But a mixed development may contain:
- apartments;
- terraces;
- semi-detached houses;
- detached houses;
- commercial units;
- and properties of substantially different sizes.
Management then needs a documented allocation method.
Possible approaches include:
Equal allocation
Every unit pays the same amount.
This is simple where properties and service benefits are broadly similar.
Weighted allocation
Different property categories receive different weights.
For example, the estate may have an agreed formula where certain property types carry a larger share of defined costs.
Benefit-based allocation
Some costs may be assigned only to properties benefiting from a particular service.
For example, residents of one apartment block may pay for the lift servicing that does not benefit detached houses elsewhere in the estate.
The correct approach depends on the estate's documents, ownership arrangements and approved rules.
Do not invent a new formula halfway through the year because one category of resident complains.
Residents should be able to see how their proportion was determined.
RICS's 2026 residential service-charge guidance similarly recommends giving residents or leaseholders an approved budget together with an apportionment schedule showing how their share was calculated. The RICS code applies to England, not Nigeria, but the transparency principle is useful for estate budgeting anywhere. (RICS)
For ownership and tenancy questions, see owners vs tenants estate dues.
Should you include maintenance reserves and contingency?
Yes, where appropriate, but the amount should have a reason.
Without some allowance for foreseeable maintenance and unexpected operating costs, a budget can fail after the first significant breakdown.
Consider predictable future work such as:
- generator overhaul;
- pump replacement;
- gate equipment replacement;
- repainting common areas;
- road repairs;
- drainage rehabilitation;
- CCTV replacement;
- and major electrical maintenance.
Some of these expenses may belong in a sinking or reserve fund rather than ordinary annual operating expenditure.
The distinction matters.
Routine gate servicing is an operating expense.
Replacing the entire gate system several years from now may be better treated as planned capital expenditure.
RICS's current residential service-charge code says an explained contingency may be appropriate when preparing a service-charge budget, while still requiring the overall estimate to remain reasonably close to expected actual expenditure. (RICS)
For long-term replacement costs, use the estate sinking fund guide.
Avoid using a random percentage simply because another estate uses it.
Look at the condition and expected life of your own infrastructure.
How do you calculate the charge for a new estate?
A new estate is more difficult because there is little historical spending data.
Start with quotations and operating assumptions.
Estimate:
- required number of security personnel;
- security contract;
- waste collections;
- electricity;
- generator hours;
- expected diesel use;
- water production;
- cleaning;
- landscaping;
- management;
- maintenance contracts;
- software;
- common-area services;
- and initial repairs.
Be careful with developer subsidies.
Suppose the developer pays the security company's first six months.
The estate may appear inexpensive to operate during that period.
But once the subsidy ends, residents may suddenly discover that the true annual service cost is significantly higher.
The budget should therefore distinguish:
Normal operating cost
from:
Temporary developer contribution
RICS's 2026 residential guidance specifically warns that initial budgets for new developments should reflect future costs and that differences caused by developer contributions or contractor warranties should be explained. (RICS)
This is important when setting up estate services before first occupancy.
Residents should know what the estate is likely to cost after temporary construction-period arrangements end.
How should service charges be explained to residents?
Do not send residents only a payment message.
Show the budget behind the amount.
A clear notice can explain:
Annual estate operating budget
N54,000,000
Number or weighting of contributing units
As approved under the estate's allocation method.
Your household's annual service charge
N540,000
Payment schedule
For example, annual, quarterly or monthly where permitted by the estate's rules.
Then provide the major spending categories.
Residents do not necessarily need every individual invoice before receiving an annual budget.
They do need enough information to understand why the charge exists.
After the year begins, management should compare:
Budget
against:
Actual expenditure
If security was budgeted at N18 million and ultimately costs N20 million, record and explain the variance.
If maintenance was budgeted at N6 million but only N2 million was spent because planned work was never carried out, that should also be visible.
Spending below budget is not automatically good management.
It may simply mean necessary work was postponed.
Use the estate budget vs actual guide to monitor this throughout the year.
There is also a specific legal point for certain Lagos tenancies.
Section 10 of the Lagos State Tenancy Law 2011 provides that where a landlord or agent requires payment for services, facilities or qualifying service charges in addition to rent, a separate receipt must be issued and the tenant is entitled to a written account at least every six months showing how the money was disbursed. (Lagos State Ministry of Justice)
That provision should not be presented as a nationwide rule for every Nigerian estate. Other locations and ownership structures may operate under different legal arrangements.
How does Kompound simplify service charge calculation and collection?
Understanding how to calculate estate service charge in Nigeria solves only the first part of the problem.
Management still has to bill the right households, record payments, track arrears, apply credits and produce useful records.
Kompound helps separate those functions.
Once the estate has approved its budget and decided each household's obligation, management can create the charge within the estate's billing system.
Kompound currently supports:
- recurring dues;
- scheduled charges;
- one-off levies;
- exemptions;
- prepaid credits;
- automatic reminders;
- payments;
- statements;
- and reporting. (Kompound)
Suppose the approved annual service charge is N540,000.
The estate can determine how that obligation should be scheduled under its own billing policy rather than tracking each resident manually in a spreadsheet.
A resident's account can then show:
Current service charge
Previous arrears
Payments received
Credits
Other approved levies
This is better than receiving an unexplained balance through WhatsApp.
Kompound's current pricing also states that it does not deduct a percentage from the estate dues it collects. The estate pays its software subscription, while money residents pay toward estate obligations goes to the estate treasury. (Kompound Pricing)
The calculation itself should still come from management.
Software should not invent the estate's budget.
The proper sequence is:
1. List the services the estate needs.
2. Estimate their realistic annual cost.
3. Add justified contingency or planned reserves.
4. Deduct applicable income or credits.
5. Determine the approved allocation method.
6. Calculate each property's share.
7. Explain the budget to residents.
8. Bill and track the charges properly.
9. Compare budget with actual spending throughout the year.
That is how service charge becomes a financial plan for running the estate rather than simply a figure residents are told to pay.
