The short answer
A flat fee is a one-off charge, the same whether you repay in three days or thirty; APR (annual percentage rate) is the yearly cost of borrowing including compulsory fees, so it lets you compare loans of different lengths. To compare two offers, first find the total naira you will repay and the naira you will actually receive, then annualise: fee ÷ amount received × 365 ÷ days held. For short, fixed-fee credit the naira figure is the more useful number; for anything that runs over months, APR shows the real price.
Nigerian lenders quote prices in at least four ways: a flat fee, a flat rate per month, a rate per year, and an amount taken off the top before you are paid. Each can make the same loan look cheaper or dearer. This article gives you one method that works for all of them. It sits under our guide to loan apps, BNPL, salary advances and Spaces, which covers the products themselves.
The four ways a price is quoted
- Flat fee
- A fixed amount or percentage charged once. ₦4,000 on ₦100,000 is 4% for the whole term.
- Flat rate per month
- A percentage of the original amount charged every month, even after you have repaid part of it.
- Annual rate on the balance
- A yearly percentage charged only on what you still owe, for the days you owe it. Overdrafts and most bank loans work this way.
- Upfront deduction
- A fee subtracted before the money reaches you. You owe the full amount but receive less.
APR converts each of these to the same yardstick: the cost per year as a percentage of the money you actually had the use of. The CBN's April 2026 exposure draft of its revised Guide to Charges proposes that banks and other financial institutions communicate all interest and lending rates on an APR basis, and the FCCPC's 2025 lending guidelines treat interest rates or APRs, charges and default fees as material terms of a digital loan.
How to work out the cost yourself
- Find the money you receive. Not the headline loan, the amount that lands in your account.
- Find the total you repay. Add every instalment and every compulsory fee.
- Subtract. Total repaid minus money received is the naira cost.
- Divide by the money received. That is the cost for the term, as a percentage.
- Annualise. Multiply by 365 and divide by the number of days you hold the money. For loans repaid in instalments, the balance falls over time, so this simple method understates the true rate; see the instalment example below.
Worked example: three offers for ₦80,000 over 30 days
These are illustrations, not quotes from any lender.
| Offer | Received | Repaid | Naira cost | Simple annual rate |
|---|---|---|---|---|
| A: flat fee of ₦6,000, paid at the end | ₦80,000 | ₦86,000 | ₦6,000 | about 91% |
| B: 4% fee deducted upfront | ₦76,800 | ₦80,000 | ₦3,200 | about 51% |
| C: 36% a year on the balance | ₦80,000 | ₦82,367 | ₦2,367 | 36% |
Offer B looks like it costs 4%, but because the fee comes off what you receive, the rate on the money you actually use is 3,200 ÷ 76,800, about 4.2% for the month. Offer C has the highest-sounding number, 36%, and is the cheapest in naira. Offer A sounds small, "just ₦6,000", and is the most expensive.
Now change the term. If you repay all three after 10 days instead of 30, Offers A and B still cost ₦6,000 and ₦3,200, because flat fees do not shrink, while Offer C falls to about ₦789. Repaying early only saves money when the cost is charged by time.
The flat monthly rate trap
Instalment loans are often priced at a flat rate per month. Take ₦120,000 over six months at 4% flat a month. Interest is 4% of ₦120,000, ₦4,800, every month, ₦28,800 in total, and you repay ₦24,800 a month.
The headline suggests 48% a year (4% × 12). But you are repaying principal each month, so by month six you owe about ₦20,000 and are still paying ₦4,800 of interest on it. Worked out on the falling balance, the true rate is about 6.5% a month, roughly 78% a year as a simple rate and over 110% compounded. As a rule of thumb, a flat monthly rate on a six-month loan costs about one and a half to two times what the headline implies.
Which number to use when
| Situation | Compare by | Why |
|---|---|---|
| Short, one-off credit with a fixed fee (salary advance, 14-day loan) | Naira cost | You know when you will repay; the fee does not change |
| Credit charged by time (overdraft, balance-based rates) | APR, then naira for your expected days | Cost depends on how long you hold it |
| Instalment loans, BNPL with interest | APR on the falling balance | Flat monthly rates hide the true cost |
| Any offer with an upfront deduction | Cost ÷ money received | The headline is on money you never get |
A benchmark to hold offers against
Once you have an annual figure, compare it with what banks charge. The CBN reset its Monetary Policy Rate to 23% in September 2026, and the average maximum lending rate charged by banks was 33.16% a year in June 2026. Those are rates for bank customers who qualify, so a small unsecured loan will usually cost more. Still, an offer running at several hundred percent a year is many times the bank benchmark, and that gap is worth seeing in numbers before you accept.
Two more checks before you decide. Find the late fee and whether it repeats, and look for anything added to the balance as "insurance" or "processing". Both count towards the real cost. For a side-by-side look at the two most common short-term options, see overdraft versus loan app, and for fixed-fee credit tied to your pay, our article on salary advances.
If a price is described with a label you do not recognise, ask two questions: per what period, and on what balance? The answer tells you which row of the table applies. The parent guide's section on what credit really costs adds hold rates to this list.
Where Pryme fits
Pryme's Spaces credit and Salary Advance are Nigeria-only. Salary Advance uses a flat fee, so its naira cost is the number to compare. Spaces credit is lent by Solid Allianze Microfinance Bank Ltd, a CBN-licensed microfinance bank, through the Pryme app, and can be spent only with merchants in Pryme's Spaces ecosystem. Its cost is shown in the app before you commit, and the full agreement is shown before you accept, with nothing drawn until you do. Ask the two questions above, per what period and on what balance, and run the method in this article before you decide. Solid Allianze, the lender, is integrated with all of Nigeria's licensed credit bureaus, and its credit decisions draw on them. As a CBN-licensed lender, Solid Allianze's credit activity sits within Nigeria's credit-reporting system, so repaying on time helps build a credit history.
Questions people ask
Is a 5% monthly interest rate the same as 60% a year?
Only if it is charged on the balance you still owe. If it is a flat rate on the original amount over several months, the true annual cost is much higher, often 90% or more for a six-month loan.
How do I calculate APR on a loan app?
Divide the total fee by the money you actually received, then multiply by 365 and divide by the number of days in the loan. A ₦7,500 fee on ₦50,000 for 14 days works out at about 391% a year as a simple rate.
Does paying a flat fee loan early save money?
Usually not. A flat fee is charged once whatever the term. Repaying early saves money when the cost is charged by time, such as an overdraft or a rate on the outstanding balance.
Why is my loan less than I applied for?
The lender has probably deducted a fee upfront. You still owe the full amount, so the effective cost is the fee divided by what you received, which is higher than the headline percentage.
Do Nigerian lenders have to show the APR?
The CBN's April 2026 exposure draft of its Guide to Charges proposes APR disclosure for banks and other financial institutions, and the FCCPC treats APRs and fees as material terms for digital lenders. Check the cost section of the agreement before you accept.
