AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
A late fee is a fixed naira charge applied when a payment is missed, sometimes once and sometimes each month. Penalty interest is a percentage charged on the overdue amount for each day or month it stays unpaid, so it keeps growing. On a ₦50,000 overdue instalment in our example, a one-off ₦2,000 fee stays at ₦2,000, while 1% a day reaches ₦15,000 after 30 days.
Two ways lenders charge for lateness
- Late fee (late payment charge)
- A fixed amount, such as ₦2,000, triggered by a missed or late payment. It may be charged once per missed instalment or every month the arrears remain.
- Penalty interest (default interest)
- An extra rate charged on the overdue amount, for example 1% a day or 5% a month, for as long as it remains unpaid. It may be simple or may compound.
Some agreements use both. Some charge penalty interest on the overdue instalment only; others charge it on the whole outstanding balance. The FCCPC's 2025 digital lending regulations require digital lenders to disclose interest rates, repayment terms and fees in full before a loan is completed (Regulation 17(a)), and the registration form in Schedule 4 asks applicants to disclose 'any penalties for late, delayed or non-payments'. The text we read does not set a maximum penalty charge.
Worked example: ₦50,000 overdue
Example only. An instalment of ₦50,000 is missed. The table shows what each kind of charge adds.
| Charge type | After 30 days | After 90 days |
|---|---|---|
| One-off late fee of ₦2,000 | ₦2,000 | ₦2,000 |
| Late fee of ₦2,000 each month | ₦2,000 | ₦6,000 |
| Penalty interest 5% a month, simple | ₦2,500 | ₦7,500 |
| Penalty interest 1% a day, simple | ₦15,000 | ₦45,000 |
| Penalty interest 1% a day, compounding daily | ₦17,392.45 | ₦72,431.63 |
The fixed fee is predictable and stops growing. Daily penalty interest is the one to fear: at 1% a day, simple, the overdue amount attracts 30% in a month and 90% in three. If it compounds, each day's charge is added to the amount on which the next day's charge is worked out: 50,000 × (1.01^30 − 1) = ₦17,392.45 after 30 days.
On the instalment or on the whole balance?
This one clause can multiply the cost. Example only: you have ₦200,000 outstanding, of which one ₦50,000 instalment is overdue. Penalty interest of 1% a day for 30 days on the overdue instalment is ₦15,000. On the whole ₦200,000 balance it would be ₦60,000. Read the default clause for the words 'overdue amount', 'arrears' or 'outstanding balance', and ask the lender if it is unclear.
How the two interact with normal interest
- On a reducing-balance loan, ordinary interest keeps accruing on the unpaid balance, so a missed payment costs you ordinary interest as well as any penalty. See working out what you still owe.
- Some agreements replace the normal rate with a higher default rate once you are late, rather than adding a separate penalty.
- A late fee added to the balance may itself attract interest or penalty interest.
- A grace period, if offered, delays the start of charges; check how 'days late' are counted.
Charges that sound like penalties but are not
Not every extra charge after a due date is a penalty. A rollover or extension fee buys more time and is often a fresh charge for a new period, which can cost more than the late fee it replaces; see what an extension costs. Recovery or collection costs may be passed on under some agreements. And some lenders describe a missed-payment charge as a 'service charge' or 'default fee'. Whatever the label, the questions are the same: is it fixed or a percentage, what is it charged on, and does it keep growing?
Which is worse for you?
For a short delay, a fixed late fee may cost more: one day late on a ₦50,000 instalment costs ₦2,000 under the fee but ₦500 under 1% a day. Beyond four days the daily penalty overtakes it and keeps going. In this example, the longer you expect to be late, the more a percentage penalty costs compared with a fixed fee. In either case, a payment made even a few days late usually costs less than one left for weeks.
What to check first
- Find the default or late payment clause in your agreement or loan screen.
- Is the charge a fixed fee, a percentage, or both?
- Is the percentage per day or per month, and is it simple or compounding?
- Is it charged on the overdue instalment or the whole balance?
- Is there a grace period, and from which day are charges applied?
- If you cannot pay, contact the lender before the due date and ask about a revised plan in writing.
If you believe a charge was not disclosed, ask the lender for a statement; for digital lenders, Regulation 21(b) says you can obtain one within 24 hours of asking. Our guide to what 1% a day adds up to runs longer timelines.

Questions people ask
What is the difference between late fee and penalty interest?
A late fee is a fixed naira amount for missing a payment. Penalty interest is a percentage charged on the overdue amount for each day or month it stays unpaid.
How much is 1% daily penalty on ₦50,000?
₦500 a day, or ₦15,000 over 30 days, if charged as simple interest on the overdue amount only. Compounding or charging on the whole balance makes it more.
Can a loan app charge any late fee it wants?
The FCCPC's 2025 regulations require fees and penalties to be disclosed before the loan is completed and bar unfair terms, but the text we read sets no maximum figure.
Do late fees stop when I start paying again?
That depends on the agreement. Arrears usually keep attracting charges until cleared. Ask the lender for a statement showing how each charge was applied.
