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
Laddering means splitting one sum into several fixed deposits with different maturity dates, for example four equal parts at 90, 180, 270 and 365 days, then rolling each into a long tenor as it matures. You get regular access to part of your money without breaking deposits, and you average out changes in rates rather than locking everything at one moment.
Putting all your savings into one 365-day fixed deposit gives you a single rate and a single date. That is fine if you are sure you will not need the money and that the rate will not rise. Most savers are sure of neither. A ladder is a simple way to keep a better rate on most of the money while part of it comes back regularly.
How a ladder works
- Divide the sum into equal parts, often four.
- Place each part for a different tenor so maturities are spaced out, for example 90, 180, 270 and 365 days.
- When the shortest one matures, either use the money or re-place it for the longest tenor in your ladder.
- Repeat. After the first cycle, every deposit is on the long tenor, but one matures every quarter.
The result is a rolling series of deposits: in steady state, a quarter of your money comes back every three months and you can decide each time whether to spend it or reinvest.
A worked plan
Example only, with assumed rates. You have ₦1,200,000. Your bank offers (hypothetically) 12% for 90 days, 13% for 180 days, 13.5% for 270 days and 14% for 365 days, all on a 365-day basis with interest at maturity.
| Rung | Amount | Tenor | Example rate | Gross interest |
|---|---|---|---|---|
| 1 | ₦300,000 | 90 days | 12% | ₦8,876.71 |
| 2 | ₦300,000 | 180 days | 13% | ₦19,232.88 |
| 3 | ₦300,000 | 270 days | 13.5% | ₦29,958.90 |
| 4 | ₦300,000 | 365 days | 14% | ₦42,000.00 |
| Total | ₦1,200,000 | ₦100,068.49 |
Each figure is principal × rate × days ÷ 365. After 10% withholding tax, which BusinessDay reported in February 2026 is deducted from interest and final for individuals, total net interest across the four rungs is ₦90,061.64. When rung 1 matures on day 90, you re-place it for 365 days at whatever rate applies then, and so on.
Compare with one big deposit
₦1,200,000 in a single 365-day deposit at 14% earns ₦168,000 gross over the year. The ladder earns less in the first cycle because three rungs are on shorter, lower-rate tenors or have not run a full year. That gap is the price of access: with the ladder, ₦300,000 plus interest is back in your hands after 90 days without any penalty. Once every rung is on the 365-day tenor, the yield difference largely disappears, provided rates hold. Whether any of these rates beats inflation is a separate question; see real interest rates in Nigeria.
Why rates do not always rise with tenor
A ladder assumes longer tenors pay more, but that is not guaranteed. The CBN's Money Market Indicators page, which publishes average deposit rates by tenor, showed for June 2024 (the latest month on the page when we checked in October 2026) a 6-month average deposit rate of 15.09% against 13.08% for 12 months. When the curve is inverted like this, the ladder still gives access, but the long rung is not the best-paying one, and you may set the ladder on shorter tenors instead. Check current quotes from your bank; see where banks publish fixed deposit rates.
Practical points
- Minimums. Each rung must meet the bank's minimum for a fixed deposit, which can be high at some banks. See minimums by bank.
- Tenor limits. Some banks cap naira deposits at 180 days (GTBank's page) or 365 days (Standard Chartered Nigeria's page), which shapes the ladder you can build.
- Maturity instructions. Set each rung's instruction separately; an auto-rollover can put a rung back on the short tenor instead of the long one. See rollover at maturity.
- Weekends. Check what happens if a maturity date falls on a non-working day.
- NDIC cover. All rungs at one bank are combined for the per-depositor limit; spread across banks if the total is large.
A simpler two-rung version
If the bank's minimum makes four rungs impractical, two still help. Example: split ₦600,000 into ₦300,000 for 180 days and ₦300,000 for 365 days. At 180 days, the first rung returns and you re-place it for 365 days, so from then on one rung matures every six months. You give up some flexibility compared with four rungs but keep the main benefit: you never have to break a deposit to reach part of your money, and you never commit all of it at a single rate on a single day.
Who a ladder suits
A ladder suits someone with a lump sum who expects to need parts of it over the next year, such as a family paying school fees each term, a small business holding a reserve, or a saver who wants to avoid guessing which way rates will go. It suits less well someone with a single known spending date, where one deposit matched to that date is simpler.
Where Pryme fits
In the Pryme app you can open more than one Fixed Box, each with its own term, which is a simple way to build a small naira ladder; the current rate for each term is shown before you commit. See Savings Boxes.
Questions people ask
What is fixed deposit laddering?
Splitting money into several fixed deposits with staggered maturity dates, then re-placing each as it matures, so part of your savings is always close to coming back.
How many rungs should a fixed deposit ladder have?
Four quarterly rungs is a common design, but it depends on how often you might need money and the bank's minimum deposit for each rung.
Does laddering reduce my interest?
In the first cycle, usually a little, because some money is on shorter tenors. Once all rungs are on the long tenor, the difference largely disappears if rates are stable.
Can I ladder across different banks?
Yes. Spreading rungs across insured banks can also keep each balance within the NDIC per-depositor limit.
