The verdict in three sentences
A microfinance institution (MFI) with 40 branches should budget 25,000 to 45,000 USD in Nairobi, or 8 to 15 million FCFA (about 12,200 to 22,900 EUR) in Bamako, for a credible corporate website delivered in 10 weeks. The loan calculator and the branch locator are the two modules that generate applications, while published regulatory reports are what reassure funders. The whole project must be built for a phone on a weak connection, with pages under 1 MB, otherwise most visitors leave before seeing your offer.
What the board is really buying
An MFI website serves three audiences: clients and prospects (artisans, traders, women's groups, farmers), partners and funders (impact investors, refinancing banks, NGOs), and the regulator. Each wants something different: a rate and a nearby branch for the first, financial statements and a governance report for the second, compliant disclosures for the third.
In Nairobi, the comparison is usually between a local agency at 25,000 USD and a regional firm at 45,000 USD, with mobile money integration (M-Pesa repayment and disbursement information, paybill numbers per product) as the deciding item. The grid below details a typical project for an MFI with 120,000 clients (2026 order of magnitude, West African market, FCFA with USD equivalent).
| Item | 2026 range (FCFA excl. tax) | Approx. USD | Comment |
|---|---|---|---|
| Scoping, workshops with management and compliance | 600,000 to 1,200,000 | 1,000 to 2,000 | 3 to 4 workshops, validated sitemap |
| Mobile-first UX/UI design (25 to 35 templates) | 1,800,000 to 3,000,000 | 3,000 to 5,000 | Brand, components, accessibility |
| Development and CMS with approval workflow | 2,500,000 to 4,500,000 | 4,200 to 7,500 | Drafting, compliance review, publishing |
| Loan calculator (5 to 8 products) | 1,500,000 to 3,000,000 | 2,500 to 5,000 | Annual percentage rate shown, PDF export |
| Locator for 40 branches with map and hours | 600,000 to 1,200,000 | 1,000 to 2,000 | Works as a list without the map |
| Regulatory documents, annual reports, financials | 400,000 to 900,000 | 700 to 1,500 | Archived by fiscal year, searchable |
| Copywriting and local-language adaptation | 600,000 to 1,200,000 | 1,000 to 2,000 | Product pages, FAQ, branches |
| Total project | 8,000,000 to 15,000,000 | 13,300 to 25,000 | Delivered in 10 weeks |
Kenyan budgets run higher (25,000 to 45,000 USD) mainly because of mobile money integration, a Swahili version and higher local day rates. The spread between the low and high end depends on the number of loan products, the number of languages and whether a pre-application form is connected to the core banking system.
The loan calculator and the low-bandwidth constraint
A good calculator does two jobs: it qualifies the request (amount, term, activity, branch) and it shows the true cost of credit, which protects the MFI on transparency. It must run on an entry-level Android phone on an unstable network. In practice, the calculation runs in the browser, with no server round trip every time a slider moves.
| Technical indicator | Typical corporate site | Target for an African MFI |
|---|---|---|
| Home page weight | 3 to 6 MB | Under 1 MB |
| Display time on 3G | 8 to 15 s | Under 3 s |
| Images | Uncompressed JPEG | WebP or AVIF, 60 to 120 KB |
| Fonts | 4 to 6 files | 1 to 2 files, latin subset |
| Calculator | Heavy script or external iframe | Under 40 KB, local computation |
| Locator | Google map loaded by default | List first, map on demand |
| Offline behaviour | None | Branch and contact pages cached |
For operations, plan about 100,000 FCFA per month (around 165 USD) for managed hosting (CDN, daily backups, SSL, monitoring), plus 75,000 to 120,000 FCFA per month for maintenance covering security updates and small content changes.
A 10-week plan
| Weeks | Phase | Deliverable |
|---|---|---|
| 1 to 2 | Scoping and content | Sitemap, product list, rate grid |
| 3 to 4 | Design | Mobile then desktop mockups approved |
| 5 to 7 | Development | CMS, calculator, locator, document area |
| 8 | Content and translation | Product pages, FAQ, 40 branch pages |
| 9 | Acceptance testing | 3G tests, accessibility, compliance sign-off |
| 10 | Go-live | Communication team training, follow-up |
The critical path is rarely technical. What delays an MFI project is rate approval by the risk department and collecting the real opening hours of 40 branches. Appoint one owner per department in week one.

Mini case study
Mrs Traoré, CEO of a 40-branch MFI in Bamako, approves a budget of 11 million FCFA (about 18,300 USD), calculator included. Before the website, the MFI received about 300 loan requests per month, all in branches. Six months after launch, the pre-application form adds 180 requests per month, 25 % of which become loans, so 45 additional loans. With an average outstanding of 750,000 FCFA and an estimated net interest margin of 12 % per year, each loan brings about 90,000 FCFA. That is 4 million FCFA of margin per month: the project pays for itself in under three months, hosting excluded. A Nairobi MFI spending 35,000 USD on the same logic reaches payback in roughly four to five months.
FAQ
How much does a mid-sized MFI website cost?
For 30 to 50 branches, plan 8 to 15 million FCFA in West Africa or 25,000 to 45,000 USD in Nairobi in 2026. An MFI with fewer than 10 branches can start around 5 million FCFA with a simplified 2 or 3 product calculator.
Can the calculator connect to our core banking system?
Yes, but it is not required at first. A first version uses a rate grid managed in the CMS; a core banking or mobile money connection usually adds 2 to 4 million FCFA (3,300 to 6,600 USD).
Should we publish our regulatory reports online?
Publishing financial statements, the annual report and governance information builds funder confidence. A document area organised by fiscal year costs 400,000 to 900,000 FCFA and is updated without a developer.
How do we guarantee a fast site on 3G?
We set a contractual performance budget: under 1 MB per page and under 3 seconds to display. Compliance is checked during acceptance on a real entry-level phone.
What is the yearly budget after launch?
Plan 1.2 million FCFA per year for managed hosting and 0.9 to 1.4 million FCFA for maintenance, about 2.1 to 2.6 million FCFA (3,500 to 4,300 USD) per year.
