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
When interest is added to an unpaid balance and the next month's interest is charged on that larger total, you pay interest on interest, so the debt grows faster each month. In a labelled example at 5% a month, ₦100,000 grows to about ₦134,010 after six months and about ₦179,586 after a year, before any late fees.
Many borrowers who fall behind are shocked by how fast the figure in the app climbs. Usually two things are happening at once: interest is being added to the balance, and separate late charges are stacking on top. This guide isolates the first effect, compounding, so you can see how it behaves and what you can do about it. Whether compounding applies at all depends on your loan agreement, so read the terms first.
Simple versus compound growth
With simple interest, each month's charge is worked on the original amount. With compound interest, each month's charge is worked on the balance including interest already added. The difference is small at first and large later.
| Month (example: ₦100,000 at 5% a month, nothing repaid) | Simple balance | Compound balance |
|---|---|---|
| 0 | ₦100,000 | ₦100,000.00 |
| 1 | ₦105,000 | ₦105,000.00 |
| 2 | ₦110,000 | ₦110,250.00 |
| 3 | ₦115,000 | ₦115,762.50 |
| 4 | ₦120,000 | ₦121,550.63 |
| 5 | ₦125,000 | ₦127,628.16 |
| 6 | ₦130,000 | ₦134,009.56 |
| 12 | ₦160,000 | ₦179,585.63 |
After six months compounding has added about ₦4,010 more than simple interest would. After twelve months the gap is about ₦19,586. The formula is balance = amount × (1 + monthly rate) raised to the number of months; at 5% a month, 1.05 to the power of 12 is about 1.796.
Why the balance grows faster than you expect
- Each month's interest is itself charged interest the following month.
- Late fees, if added to the balance, also start attracting interest.
- Penalty interest, where the agreement allows it, raises the rate itself, so the multiplier gets bigger.
- Partial payments that do not cover the month's interest leave the balance higher than before.
The last point catches many people. In the example, month one's interest is ₦5,000. Paying ₦3,000 that month still leaves the balance at ₦102,000, and the next month's interest is charged on that.
How to read your own balance
- Ask the lender for a statement showing principal, interest, fees and penalties as separate lines.
- Check the agreement for how interest is charged after the due date: on principal only, or on the whole balance.
- Check whether late fees are added to the balance or charged separately.
- Recalculate one month yourself. If the lender's figure is higher than your calculation, ask for an explanation in writing.
For digital lenders, the FCCPC's 2025 consumer lending regulations say interest, fees or charges may vary only where the loan agreement expressly provides for it, and lenders must itemise penalties for late or non-payment. The regulations contain no explicit cap on interest and do not expressly ban interest on interest, though the FCCPC says it will monitor whether rates are exploitative. Check the regulations' current enforcement status. This is information, not legal advice.
Daily compounding works the same way
Some lenders add interest daily rather than monthly. The effect is slightly larger. In a labelled example, 5% a month added as one-thirtieth each day for 180 days turns ₦100,000 into about ₦134,952, against ₦134,010 with monthly compounding. The difference is under ₦1,000 here; the rate and the time unpaid matter far more than how often interest is added.
A worked recovery example
Labelled example. You stopped paying for six months and now owe ₦134,009.56, still at 5% a month. If you restart at ₦20,000 a month, the balance is cleared in nine payments totalling about ₦167,362, so roughly ₦33,352 of that is further interest. If the lender agrees in writing to freeze interest at ₦134,009.56, the same ₦20,000 a month clears it in seven payments, the last one smaller. That is why a written freeze is worth asking for before you start repaying, not after.
Stopping the growth
Any payment that covers more than the month's interest starts shrinking the balance, and every naira of principal you clear also cuts future interest. If you cannot pay in full, contact the lender before the balance grows further and ask for a written settlement or a payment plan that freezes interest. See how to negotiate a settlement with a loan app and what happens when you default on a loan app. If you are being harassed while you sort it out, read your rights against loan app harassment.
When you owe several lenders, list each balance with its monthly rate and whether it compounds. Every extra naira should go to the debt growing fastest, while you keep at least the agreed minimum going to the others. Clearing a small compounding balance can save more than chipping at a large simple one, because each month it stays open the interest grows on itself.

Questions people ask
Can a loan app charge interest on interest in Nigeria?
It depends on the loan agreement. The FCCPC's 2025 regulations do not expressly ban it, but charges may only vary where the agreement provides for it. Read your terms and ask for an itemised statement.
Why is my loan balance increasing even though I am paying?
Your payments may be smaller than the interest and fees added each month, so the balance still grows. Pay at least the month's interest plus something towards principal.
How much will my loan grow if I stop paying?
Multiply the balance by one plus the monthly rate for each month unpaid. At 5% a month, ₦100,000 becomes about ₦134,010 in six months, before fees.
What is the fastest way to stop a loan balance growing?
Pay more than the monthly interest, ideally clear the principal, or agree a written plan with the lender that freezes further interest.
