Cheapest Citizenship by Investment in 2026: All-In Cost Ranking

As of July 2026 the cheapest citizenship by investment Civita can verify from a complete official schedule is Nauru. Its program office publishes a $90,000 contribution through December 31, 2026, discounted from the $115,000 standard amount. Civita’s modeled total is about $114,700 for a single applicant and $126,700 for a family of four after published government charges and stated professional-fee assumptions. Among established programs, Vanuatu is the low-cost leader. Among Caribbean programs that retain stronger mobility, Dominica is the lowest for one person. The headline contribution almost never equals what you wire.

This page ranks specific routes by modeled entry cash for a stated applicant profile and flags the trade-offs a low sticker price can hide. It is not a provider quote or a promise of final cost.

How “cheapest” really works

A citizenship by investment (CBI) price has three layers, and comparison tables that show only the first one are misleading.

1. The qualifying investment. Usually a non-refundable donation to a government fund, or a larger real estate purchase you hold for several years.
2. Government and statutory fees. Due diligence (background checks), application or processing fees, passport issuance, and oath or naturalization certificates. These scale with the number of applicants.
3. Professional fees. Your licensed agent or law firm. In the Caribbean these typically run $15,000 to $30,000 for a single applicant and are not optional, since most programs require a licensed agent to file.

A program with the lowest donation can end up costing more than a rival once due diligence and per-person fees are added, especially for families. The right question is never “what is the donation,” it is “what is the total for my exact family, and what is the passport worth.”

Modeled entry-cash ranking, single applicant (2026)

These figures come from Civita’s reviewed publication models for one adult. Each model states its professional-fee assumption and exclusions. Treat them as orientation, not quotes.

Program	Qualifying amount	Modeled charges above it	Modeled entry cash, single	Current planning time
Nauru	$90,000 contribution promotion	$24,700	$114,700	about 3 to 4 months
Vanuatu	$130,000 mandated fee	$5,000	$135,000	decision within 3 months by statute
Dominica	$200,000 EDF contribution	$22,000	$222,000	about 6 to 12 months or more
Grenada	$235,000 NTF contribution	$24,000	$259,000	about 6 to 8 months
Antigua & Barbuda	$230,000 NDF contribution	$33,500	$263,500	measured files often 12 to 18 months
St Lucia	$240,000 NEF contribution	$25,000	$265,000	measured files have ranged about 12 to 26 months
St Kitts & Nevis	$250,000 SISC contribution	$25,000	$275,000	official decision target 120 to 180 days, plus preparation
Turkey	$400,000 qualifying property	$29,000	$429,000	about 6 to 12 months

Nauru is the newest and cheapest verified ticket in the ranking, and it carries more operating-history and mobility risk than established programs. Vanuatu wins on price and speed among programs with a multi-year track record but loses on passport strength. Among Caribbean options, Dominica is the cheapest single-applicant donation at a $200,000 floor with relatively light statutory fees.

The new verified floor: Nauru

Nauru’s Economic and Climate Resilience Citizenship Program began taking applications in early 2025. The standard contribution is $115,000 for a single applicant; the official contribution page currently publishes a $25,000 discount for applications filed by December 31, 2026. On top sit a $5,000 application fee, $6,000 principal due-diligence fee, about $1,200 in bank charges and $500 per passport. That produces $102,700 in published principal-applicant charges before professional fees, or about $114,700 using Civita’s stated $12,000 professional-fee assumption. The program office gives a three-to-four-month timeline.

Sao Tome and Principe is monitored, not ranked. Decree-Law 7/2025 established nationality by investment or donation on August 1, 2025. Civita has not located a current administering-authority fee schedule, family schedule and application process sufficient to place it in a cost ranking. Third-party firms publish attractive prices and timelines, but those claims do not meet the primary-source standard used by this dataset. It will enter the ranking when the administering authority publishes enough material to reproduce the model.

Now the honest part, because a price this low is doing a lot of the selling on its own:

• Nauru has a short track record. Buyers are early customers of a program with less public outcome data than the established Caribbean routes.
• The travel document is limited. There is no visa-free Schengen access. This is a legal second citizenship, not a European-mobility product.
• The Vanuatu precedent hangs over both. Vanuatu was once the budget king of this market. The EU first partially suspended its waiver in 2022, required visas for all Vanuatu nationals from February 2023, and made that removal permanent from 3 February 2025 after the Council adopted the measure on 12 December 2024. Cheap programs that scale fast attract exactly the scrutiny that destroys the value they promise, and the EU’s reformed visa-suspension mechanism now treats operating an investor-citizenship program as, in itself, grounds for suspension.
• Repeated discounting can be a demand signal. Extending a promotion may indicate price sensitivity, but that is an inference rather than a published government explanation. It belongs in risk analysis, not as a proven motive.

If what you need is a legal second citizenship at the lowest verifiable outlay and you have priced in those risks, Nauru is now the floor. If you are buying mobility or durability, keep reading.

The Caribbean floor: why the donations cluster

In 2024 the five Eastern Caribbean CBI states agreed a coordinated $200,000 minimum on donation routes to stop a price war. That is why Dominica, Antigua, Grenada, St Lucia and St Kitts now sit so close together. The differences are in fees, family rules and passport perks, not the base price.

• Dominica. $200,000 for a single applicant, $250,000 for a family of four. Due diligence is $7,500 for the main applicant and $4,000 per dependent aged 16 and over, plus a $1,000 processing fee, a $1,000 interview fee per adult, and a $500 naturalization certificate per person. A clean Caribbean passport with Schengen access; a UK visa has been required since July 2023. Among the lowest all-in costs in the region.

• St Lucia. The National Economic Fund donation is $240,000, and that figure covers a single applicant or a main applicant plus up to three family members. Due diligence is $8,000 for the main applicant and $5,000 per dependent 16+, processing $2,000 main and $1,000 per dependent. The flat $240,000 for up to four people makes St Lucia competitive for small families even though its single-applicant price is higher than Dominica’s.

• Antigua & Barbuda. The National Development Fund donation is $230,000 and already covers a family of up to four, which makes Antigua one of the cheapest options for couples and small families rather than for solo applicants. A separate University of the West Indies fund route covers a family of six or more for around $260,000. Government processing is about $10,000 and the main applicant pays roughly $8,500 due diligence. The interview fee is $1,500, higher than peers. Antigua also requires a short physical presence (five days within five years) to retain citizenship.

• Grenada. The National Transformation Fund donation starts at $235,000 including a family of up to four. Grenada’s distinguishing feature is a US E-2 investor visa treaty, which lets Grenadian citizens apply to live and run a business in the United States. That single benefit is why many applicants pay slightly more here.

• St Kitts & Nevis. The oldest program, with a Sustainable Island State Contribution floor of $250,000, the highest Caribbean donation. You are paying a premium for the longest track record and arguably the most recognized brand.

Vanuatu: the cheapest established program, with a real catch

Vanuatu’s Development Support Program publishes a $130,000 government-mandated single-applicant fee plus $5,000 in FIU due diligence. Its Citizenship Act requires the Commission to decide a DSP application within three months; passport issuance follows approval. Professional and passport costs sit on top, and applicants should confirm the current interview, biometric and collection steps before filing because the government is implementing further integrity reforms.

The catch is mobility and reputation. The EU first partially suspended Vanuatu’s waiver in 2022, extended the visa requirement to every Vanuatu national from 4 February 2023, and made the removal permanent from 3 February 2025 after the Council adopted the measure on 12 December 2024. The passport therefore no longer opens Europe the way a Caribbean one does. If your goal is cost and a fast second document for visa-free travel within Asia and parts of the Commonwealth, Vanuatu can offer value (the UK and Schengen waivers are gone). If you want durable European access, the Caribbean is worth the extra spend.

Turkey: higher entry cash, with an asset to sell

Turkey’s $400,000 minimum is on real estate, not a contribution, and the title carries a three-year no-sale restriction. After that period the property may be sold, but no rule guarantees the purchase price, a buyer, or a dollar-denominated outcome. Turkey also gives access to a large G20 economy, a strong regional passport and no physical residency requirement. Model the full entry cash, holding and transaction costs, currency exposure, and several resale scenarios rather than subtracting the $400,000 at par.

Cost is not the same as value

The lowest number on the table is rarely the best decision. Weigh these against price:

• Passport strength. Caribbean passports offer Schengen access, and three of the five (St Kitts, Grenada, Antigua) still offer the UK; Dominica and St Lucia do not. Vanuatu offers neither Schengen nor the UK. Check current visa-free counts before deciding.
• Family economics. In the current standard family-of-four models, Grenada is about $272,000 and St Lucia about $273,000, followed by Dominica at $278,500, Antigua at $282,500 and St Kitts at $291,500. Exact ages and relationships can change the order, and Antigua’s UWI route may suit larger families.
• Due diligence rigor. Stricter screening costs more and takes longer, but a well-vetted program is less likely to face visa-free downgrades later. Cheap-and-loose can become expensive if the passport weakens.
• Tax. None of these countries taxes you simply for holding citizenship, but your home-country and residency tax position can change. Treat tax as something to coordinate with qualified counsel, not a reason to choose a program.

A note on real estate routes: property options usually carry higher government fees and resale risk. Later sale proceeds depend on price, liquidity, tax and transaction costs. Run the contribution and property routes side by side without assuming a par exit.

Bottom line

As of July 2026, the lowest reviewed entry cash in Civita’s model is Nauru, at about $114,700 for one person and $126,700 for the stated family of four under the promotion published through December 31, 2026. Sao Tome and Principe remains monitored rather than ranked until its administering authority publishes a reproducible operational and fee schedule. Vanuatu follows at $135,000 for one applicant, with the major caveat of weaker travel access. In the Caribbean, Dominica leads the single-applicant model, while Grenada narrowly leads the stated family-of-four profile and St Lucia follows closely. Build the decision on modeled entry cash, the status received and current travel access, not the headline contribution.
