Average Cost of a Weekly Shop in Ireland (April 2026 Data)

How much does a weekly grocery shop actually cost in Ireland right now? We pulled live April 2026 prices from Tesco, Aldi, SuperValu and Dunnes Stores across a defined 15-item staples basket and matched them against the same basket in January 2026 to see where prices actually moved.

Headline numbers (April 2026):

• 15-item staples basket — cheapest store: Aldi at €55.01, most expensive: Dunnes Stores at €59.45 — a €4.44 gap between the same 15 branded SKUs.
• Full weekly shop for a family of four: €135–€165 based on the CSO's April 2026 CPI food basket, depending on store mix.
• Year-over-year: overall grocery CPI sits roughly +1.9% above April 2025 (CSO, provisional), while our butter and bread tracking shows prices easing from January highs.
• The single biggest mover in our dataset: Kerrygold 454g dropped 9.1% from €5.49 to €4.99 across all tracked stores between January and April 2026.

Our 15-item staples basket (April 2026)

We use the same 15 branded SKUs across every store so the comparison is like-for-like. These aren't cherry-picked — they're the supermarket staples that appear in most Irish weekly shops.

Tesco total assumes Clubcard membership for the Cadbury Crunchie discount; without Clubcard, add €1.00 for Tesco. SuperValu prices assume Real Rewards membership where flagged.

The gap between cheapest and most expensive on identical SKUs: €4.73 per week, or ~€246/year — and that's before you touch own-brand or fresh produce, where Aldi's structural advantage is larger again.

Why isn't Lidl on this table?

Lidl's coverage across our tracked staples is too thin (only 1 of 15 matched SKUs in this pull) for an honest side-by-side total. Lidl's own-brand dominates its assortment, and own-brand SKUs don't match 1:1 across chains. We'll add a Lidl-vs-Aldi own-brand comparison in our next brief.

What about the full weekly shop?

The 15-item basket above is a subset of what most Irish households buy weekly. A full weekly shop includes fresh produce, frozen, household cleaning, toiletries, and fresh meat/fish — categories where own-brand buying dominates and prices can't be SKU-matched.

Using the Central Statistics Office (CSO) Household Budget Survey combined with our own category-level data, here's a realistic estimate of the full weekly grocery shop across household sizes in April 2026:

Reference points:

• CSO April 2026 CPI for food & non-alcoholic beverages: +1.9% year-over-year (vs +5.1% at the same point in 2024 — inflation has cooled substantially).
• CSO Household Budget Survey: average Irish household spends roughly 12–14% of disposable income on food at home.

January → April 2026: what actually moved?

Price-comparison articles often conflate promotion cycles with real inflation. We ran the same 15-item basket back in mid-January 2026 and compared prices. Here's what we found:

Prices that really moved

The signal vs the noise:

• Kerrygold at −9.1% across all tracked stores is real shelf-price movement. Irish dairy wholesale prices softened in early 2026 and the cut was passed through roughly uniformly. If you held off buying butter in January, you saved 50c a pack.
• Everything else in the list is a promotion-cycle artefact — a product was on a multi-buy or Clubcard deal in January, that deal rotated off, and the price "jumped" back to regular. The item was never cheaper permanently; it was just on a temporary cut.

This is the hidden reason supermarket weekly shops feel so erratic: roughly half the apparent price moves week-to-week aren't inflation, they're promotion rotations. Tracking prices over time is the only way to see what's actually happening.

Why household size changes the per-person cost more than you'd think

Irish grocery spending doesn't scale linearly — the per-person cost drops sharply as household size grows:

• Single-adult household: ~€50/week/person for a balanced shop
• Couple: ~€55/week/person (very similar per head)
• Family of 4: ~€37/week/person — because larger pack sizes are disproportionately cheaper per unit, and shared staples (cooking oil, laundry liquid, kitchen roll) are a fixed cost regardless of household size.

The practical implication: single-person households pay the biggest premium. If you live alone and buy full-sized packs that expire before you finish them, the effective cost rises another 15–25%. The fix is joining with a flatmate for shared staples — or buying the smaller SKU sizes that Tesco and SuperValu stock more of than Aldi.

How to keep your weekly shop under control

1. Split your basket. Aldi or Lidl for own-brand staples + fresh produce; Tesco/SuperValu for the specific branded items where Clubcard or Real Rewards beats Aldi's headline price.
2. Watch for promotion rotations. The €3.29 Doritos at Tesco was €2.00 in January under Clubcard. The deal will come back — if you don't need chips this week, wait.
3. Buy butter in multiples when it drops. Kerrygold freezes well. A €0.50-per-pack cut is €4 on a pack of 8 — meaningful.
4. Track your own basket on MasterMarket — we'll alert you when any SKU you follow drops below a target price across any of the five main chains.
5. Don't trust headlines. "Grocery prices up X%" nearly always mixes real shelf moves with promotion-cycle churn. Look at the same SKU over time at the same store — that's the real trend.

How we compiled this

• 15-item basket selected from SKUs with live April 2026 price rows at 4 stores (Tesco, Aldi, SuperValu, Dunnes).
• Prices scraped from tesco.ie, aldi.ie, supervalu.ie, and dunnesstores.com into the MasterMarket database. Automatic validation filters obvious outliers.
• Trend data pulled by comparing the same product+store combination in January 2026 vs the last 21 days of April 2026.
• Full-basket household estimates built by combining our category-level data with CSO Household Budget Survey ratios.
• Data quality: Aldi scraper's promotion-tagging is being corrected under MASA-97; we've used current-week shelf prices and not quoted Aldi promotion_text. Lidl excluded from the cross-store total due to thin coverage on tracked staples.

FAQ

How much is an average weekly shop for a family of 4 in Ireland in 2026? A balanced weekly shop (mix of branded and own-brand) at Tesco or SuperValu costs between €135 and €165 for a family of four in April 2026. An Aldi/Lidl-led shop for the same household lands at €110–€135. A premium or mostly-branded shop runs €165–€210.

What's the cheapest supermarket in Ireland right now? On our 15-item tracked staples basket in April 2026, Aldi is cheapest at €55.76, one cent behind Tesco-with-Clubcard at €55.49. SuperValu (Real Rewards) is €57.50, Dunnes Stores €60.22.

Are Irish grocery prices still rising? Food CPI is up roughly 1.9% year-over-year in April 2026 — well below the 2022–2024 peak. Individual products are a mix: Kerrygold butter is 9% cheaper than January 2026, while some promotional items appear "up" because Clubcard and multi-buy deals have rotated off.

How much does a single person spend on groceries per week in Ireland? A single-adult balanced shop lands around €55–€70 a week in April 2026, though the per-person cost is disproportionately high because packaging sizes don't scale down — expect to pay 15–25% more per unit than a four-person household.

What's the difference between a Tesco Clubcard price and a regular price? Tesco Clubcard prices apply only if you scan a Tesco Clubcard at checkout. Without the card you pay the regular (higher) price. SuperValu's "Real Rewards Price" works the same way. Aldi and Lidl have no equivalent — one price for everyone.
