The business has changed shape four times and never changed what it was rooted in. Each version was built out of what the last one could not do.

2016E-commerce

An online grocery store, built out of a faulty tab. Selling the food was the easy part — taking the money for it, and moving it, turned out to be the business.

2018OjirehPrime Card

A prepaid card. The first time the company issued rather than resold, and the first time it carried the obligations that come with holding somebody else’s money.

2020Microfinance bank

PrymeSolid Allianze acquired — an existing bank with an existing licence. The perimeter stopped being someone else’s to draw.

2023Multicurrency

More than one currency on one balance, and the rebrand to Pryme. A Nigerian business could hold dollars without holding a second institution.

2026Agentic operations

Accounts that do the work rather than only hold value. Five agents on the account, inside a policy you write — which is where the new mark starts.

Questions

The things people ask us first.

What is Pryme?

Pryme is a financial technology company. It gives people and businesses in Nigeria one account that holds Naira alongside dollars, pounds and euros, and a set of agents that do the running of it — keeping the books, chasing what is owed, answering customers and paying bills. Nothing leaves an account without the owner’s approval.

Can I hold dollars, pounds and euros in a Pryme account?

Yes. A Pryme account holds Naira, US dollars, pounds sterling and euros side by side on one ledger, each with its own account details — a Nigerian account number, a US account number, a UK sort code and an IBAN for the euro area. You can swap between them at a rate you set, and every currency has its own statement.

What is Spaces?

Spaces is available in Nigeria. It gives a shopper money to spend that can only be spent with a participating business. The business is paid into its Naira account whether or not the shopper repays, because Pryme carries the credit. For the business it is free to join, there is nothing monthly, and the customer’s identity is never shown — only a reference and what it is worth.

What do the agents on a Pryme Business Account do?

Five agents come with the account. The Chief of Staff runs the week and keeps what is stuck moving. Finance watches the money and keeps the books as you trade. Compliance keeps the filings on time and screens what moves. Sales chases what you are owed. Customer Support answers your customers and follows up. Each has a job description, a budget and a ceiling you set, and each one proposes rather than acts — nothing leaves the account without your signature.

How does Pryme Pay work?

Pryme Pay takes payments on your own site or on a checkout page you control. The buyer is given a one-time account number and transfers to it from any bank app or by USSD — no card, no OTP, nothing to type in. The money lands in the same account your agents are running, already matched to the order and already in your books.

What are Savings Boxes?

Savings Boxes are separate pots inside a Pryme account, held in Naira. Flexible Boxes can be withdrawn at any time, Fixed Boxes hold to a date, Investment Boxes hold for longer, and Interest-free Boxes earn nothing by design. A business can use them to ring-fence payroll and the tax it withholds, so that money cannot be spent by accident.

Who holds my money, and is it protected?

Pryme is a financial technology company, not a bank. Accounts and deposits are provided by Solid Allianze Microfinance Bank Limited, which is licensed by the Central Bank of Nigeria and is a member of the Nigeria Deposit Insurance Corporation.

Can I build on Pryme?

Yes. Pryme Rails lets a platform issue a dedicated Naira account number to each of its own customers, collect into it and reconcile against it, over one API — the same rails the Pryme Business Account runs on.

What is Pryme?

Pryme is a financial technology company. It gives you one account that holds US dollars, pounds sterling and euros beside Naira, with an assistant that runs the account for you and asks before anything moves. Accounts are provided in Nigeria today, and further markets open as each licence lands.

Can I open a Pryme account from outside Nigeria?

Accounts are provided in Nigeria today, subject to verification and approval. Foreign-currency balances are held and converted inside that account, so you can hold, receive and swap dollars, pounds and euros wherever you are.

Which currencies can I hold with Pryme?

Naira, US dollars, pounds sterling and euros, side by side on one ledger. Each has its own details — a Nigerian account number, a US account number, a UK sort code and an IBAN for the euro area — and each has its own statement.

How do I send money to Nigeria with Pryme?

Swap at a rate you set rather than the rate of the day, then send to any Pryme username or to a Nigerian bank account. There is no fee to send to another Pryme account.

What does the assistant do?

Eva is the assistant inside the Pryme app. She opens accounts, moves money, saves toward your goals, pays what is due and follows up what is owed to you — and asks you before anything moves.

What is Pryme Rails?

Pryme Rails lets a platform issue a dedicated Naira account number to each of its own customers, collect into it and reconcile against it, over one API — the same rails the Pryme Business Account runs on.

How to build a naira loan calculator in Excel or Google Sheets

Use PMT, monthly rates and a simple schedule to build your own naira loan calculator in Excel or Google Sheets, cell by cell.

PE
Pryme editorialLoans arithmetic desk · 19 Oct 2026 · 5 min read
The short answer

Put the loan amount, the monthly rate and the number of months in three cells, then use =PMT(rate, months, -amount) to get the equal monthly repayment. Excel and Google Sheets both require the rate and the number of payments in the same units, so a yearly rate must be divided by 12 for monthly payments. A schedule then follows from four simple columns: interest, principal, payment and balance.

What you are building

A calculator that tells you, for any reducing-balance loan with equal monthly payments: the monthly repayment, the total paid, the total interest, and a month-by-month schedule showing how the balance falls. It works the same in Microsoft Excel and Google Sheets. It will not model flat-rate loans or one-off fees on its own; a section below shows how to add those.

Step 1: the inputs

CellLabel (column A)Value (column B)
B1Loan amount (₦)600000
B2Annual rate30%
B3Months18
B4Monthly rate=B2/12
B5Upfront fee (₦)0

Example only: ₦600,000 at 30% a year over 18 months. If your lender quotes a monthly rate, type it straight into B4 instead and ignore B2. Microsoft's PMT documentation says to keep rate and number of payments consistent: for a four-year loan at 12% a year paid monthly, use 12%/12 and 4*12. Google's help page gives the same instruction.

Step 2: the repayment and totals

CellLabelFormulaResult in the example
B7Monthly repayment=PMT(B4,B3,-B1)₦41,802.05
B8Total repaid=B7*B3₦752,436.87
B9Total interest=B8-B1₦152,436.87
B10Effective monthly rate after fee=RATE(B3,-B7,B1-B5)2.50% while the fee is 0

The minus sign before B1 makes the payment show as a positive number; without it, PMT returns a negative figure because it treats money paid out as negative. Excel's syntax is PMT(rate, nper, pv, [fv], [type]); Google Sheets uses the same order. Leave fv and type blank for an ordinary loan that ends at zero with payments at the end of each month. Microsoft notes PMT covers principal and interest only, not fees, which is why B10 is there.

Step 3: the schedule

Start at row 13 with headings: Month, Opening balance, Interest, Principal, Payment, Closing balance.

  • A14: 1. A15: =A14+1, then fill down to month 18.
  • B14: =$B$1. B15: =F14 (last month's closing balance).
  • C14: =B14*$B$4 (interest on the opening balance).
  • E14: =$B$7 (the fixed payment).
  • D14: =E14-C14 (what is left repays principal).
  • F14: =B14-D14 (closing balance).
  • Fill rows 14 to 31 down. The closing balance in month 18 should show 0, or a few kobo either side from rounding.

First three rows of the example

MonthOpeningInterestPrincipalPaymentClosing
1₦600,000.00₦15,000.00₦26,802.05₦41,802.05₦573,197.95
2₦573,197.95₦14,329.95₦27,472.10₦41,802.05₦545,725.85
3₦545,725.85₦13,643.15₦28,158.90₦41,802.05₦517,566.95

Add a check cell: =SUM(C14:C31) should equal B9, total interest. If it does not, a formula has been filled down wrongly. Our guide to reading an amortisation schedule explains what each column means.

Step 4: useful extras

Upfront fees

Type the fee in B5. B10 then uses RATE to find the monthly rate on the cash you actually received. Microsoft's RATE page notes that it works by iteration and returns #NUM! if it cannot settle on an answer; if that happens, add a guess as the sixth argument, such as 0.03. Multiply by 12 for a nominal annual figure, or use =(1+B10)^12-1 for the effective annual rate, as covered in effective interest rate explained.

Flat-rate comparison

Add B12: =(B1+B1*B4*B3)/B3. That is the monthly instalment if the same rate were charged flat on the original amount. In the example it is ₦48,333.33, against ₦41,802.05 on the reducing balance. See flat rate versus reducing balance for why.

Extra payments

Insert a column between Payment and Closing called Extra. Change the closing balance formula to =B14-D14-G14, where G is the extra column, and type any lump sum you plan to pay in the month you plan to pay it. The schedule will reach zero earlier, and the interest column will show what you save. This only reflects reality if your lender charges interest on the reducing balance and accepts part prepayments without a fee; check your agreement before relying on it.

Weekly or daily loans

Some loan products in Nigeria are repaid weekly. The calculator works the same way, with weekly units throughout: put the weekly rate in B4 and the number of weeks in B3. Never mix a monthly rate with a weekly count. Both Microsoft and Google make this point in their PMT documentation, and it is the most common reason a home-made calculator gives a nonsense answer.

Balance after any month

To check what you owe after k payments without the schedule, use =-FV(B4, k, -B7, B1) in either program, replacing k with the number of payments made.

What to check first

  1. Is the rate quoted monthly, yearly or flat? The calculator assumes reducing balance.
  2. Are payments monthly? If weekly, use a weekly rate and number of weeks.
  3. What fees are deducted or added? Put them in B5.
  4. Does the closing balance end at zero? If not, recheck the fill-down.

Questions people ask

How do I calculate loan repayment in Excel?

Use =PMT(monthly rate, number of months, -loan amount). Divide a yearly rate by 12 for monthly payments, as Microsoft's PMT guidance says.

Does Google Sheets have a loan calculator?

Google Sheets has the PMT function with the same argument order as Excel. Add a schedule with interest, principal and balance columns to build a full calculator.

Why is my PMT result negative?

PMT shows money paid out as negative. Put a minus sign before the loan amount, or before PMT, to show a positive repayment.

Can Excel calculate a flat rate loan?

PMT assumes reducing balance. For a flat loan, use (amount + amount × monthly rate × months) ÷ months.
