10 ways Claude can save you money

The quick ones (do these tonight) ⚡

1. 🧾 Find your forgotten subscriptions. Export the last 3 months of bank and card statements as CSV, upload them together, and ask Claude to list every recurring charge with merchant, renewal date, and annual cost, sorted biggest first. The average person estimates they spend $86 a month on subscriptions and actually spends $219 (C+R Research), and 42% admit they're still paying for something they stopped using.

   Here are my last 3 months of bank and card statements: [upload the CSVs].
   
   List EVERY recurring charge, as a table: merchant, amount, billing
   frequency, next renewal date, annual cost. Sort by annual cost, biggest
   first. Add a total at the bottom.
   
   Then flag three groups separately:
   1. Duplicates, where I'm paying twice for the same kind of service.
   2. Trials that converted, a small charge that became a bigger one.
   3. Anything charged monthly that would be cheaper annually, with the saving.
   
   For each one tell me the cancel route (account settings, app store, or
   phone), because some are deliberately harder than others.

2. 🥕 Cook what you already own. Photograph your fridge, freezer, and pantry, upload all three, and ask for five dinners using only what's visible plus a maximum of six extra ingredients, with the shopping list and which meal to cook first so nothing spoils. Households spend around $762 a year on food that ends up as surplus (ReFED 2026).

   Here are photos of my fridge, freezer and pantry: [upload all three].
   
   List what you can actually SEE. If you're unsure what something is, say
   so rather than guessing.
   
   Then give me 5 dinners using only those items plus a maximum of 6 extra
   ingredients total across all 5 meals. For each: what it uses up, rough
   cook time, and how many it serves.
   
   Then tell me which meal to cook FIRST based on what looks closest to
   spoiling, and give me the 6-item shopping list as one line I can read
   off in the shop.
   
   I have [any allergies / things I don't eat] and about [X] minutes on a
   weeknight.

3. 🔧 Diagnose the repair before you book it. Photograph the appliance's model plate and the error code, upload both, and ask for the three most likely causes ranked by probability, the part and price range for each, and the test that confirms which one it is. A fridge call-out alone runs $150 to $200 before any parts (HomeAdvisor).
   paste into Claude

   Here's the model plate and the error code from my [appliance]:
   [upload both photos].
   
   It's doing this: [describe the symptom, when it started, what you already
   tried].
   
   Give me the 3 most likely causes, ranked, with a rough likelihood for
   each. For every cause:
   - the part name and its typical price range
   - the ONE test I can safely do myself to confirm or rule it out
   - whether this is a DIY fix or genuinely needs a technician
   
   Then tell me plainly whether this appliance is worth repairing at all,
   given its age and the repair cost versus replacement.
   
   Do not tell me to do anything involving mains electricity, gas, or
   sealed refrigerant systems. Flag those as technician-only.

4. 📦 Sell your clutter properly. Upload 4 to 6 photos of the item with brand, model, and condition, and ask for a search-optimized title, a description that pre-answers the three questions buyers always DM, a price with a floor, and the reply for lowball offers. The average Australian household is sitting on roughly $7,000 of unwanted items (Gumtree x YouGov).
   paste into Claude

   Here are photos of something I'm selling: [upload 4 to 6].
   Brand: [ ]  Model: [ ]  Age: [ ]  Condition, honestly: [ ]
   Selling on: [Facebook Marketplace / Gumtree / eBay / other]
   
   Write me:
   1. A search-optimised title, using the words a buyer would actually type,
      including the model number.
   2. A description that pre-answers the 3 questions buyers always message
      about (why you're selling, any flaws, whether it works).
   3. An asking price, a realistic expected price, and a floor I shouldn't
      go under. Say what you based those on.
   4. My reply to a lowball offer that keeps the buyer engaged instead of
      ending the conversation.
   
   Point out anything in my photos that's costing me money: bad angles,
   clutter in shot, a flaw I should photograph honestly rather than hide.

The ones that pay you back every month 💪

1. 📞 Your bill retention script. Paste your current internet or phone bill plus the three cheapest competitor plans you can find, and Claude builds your call sheet: opening line, the competitor price to quote, two concessions to ask for, and what to say when they say no. About 70% of people who haggle get a discount or perk, but only 39% ever try (Consumer Reports).
   paste into Claude

   Here's my current [internet/phone] bill: [paste or upload].
   Here are 3 competitor plans and prices: [paste].
   
   Build me a retention call sheet:
   1. My opening line, calm, not threatening to leave in sentence one.
   2. The exact competitor price to quote, and when in the call to bring it up.
   3. Two concessions to ask for if they won't drop the price (speed upgrade,
      fees waived, promo rate), ranked by which they usually give up first.
   4. Exactly what to say when they first say no.
   5. My walk-away line if they hold firm, and whether walking away is
      actually worth it given my contract.
   
   Keep it to one page I can read off while I'm on hold.

2. 🛡️ The real insurance comparison. Upload your renewal and two competing quotes and ask for a side-by-side table of excess, sub-limits, and exclusions, so you compare actual cover instead of headline premiums. Drivers who switched insurers saved a median $461 a year in Consumer Reports' survey of 40,000+ policyholders (source). Preparation only: the final pick is yours or your broker's.
   paste into Claude

   Here's my renewal notice and two competing quotes: [upload all three].
   
   Build a side-by-side table comparing what actually matters, not the
   headline premium:
   - annual premium and excess
   - what IS covered, with sub-limits
   - what is EXCLUDED, in plain English
   - anything one policy covers that the others don't
   
   Then tell me the 3 differences most likely to cost me real money at
   claim time, and write the 5 questions I should ask each insurer before
   switching.
   
   Be explicit about anything you can't determine from these documents
   rather than assuming it's standard.

3. 🏠 Your rent renewal case. Paste your rent, lease end date, and 8 to 10 comparable listings from your suburb, and Claude calculates the median, writes the renewal email leading with your payment history, and gives you a fallback ask if they refuse. 47% of renters never negotiate at all, and of the ones who do, more succeed than fail (Apartments.com, Oct 2025).
   paste into Claude

   My current rent: [$X per week/month]. Lease ends: [date].
   I've been here [X] and my payment history is [describe].
   Here are 8 to 10 comparable listings in my suburb: [paste].
   
   1. Work out the median asking rent for genuinely comparable places, and
      say which of my comparables you excluded and why.
   2. Tell me honestly whether I have a case, or whether the market has
      moved against me and I should just accept.
   3. If I have a case, write the renewal email: lead with my payment
      history and how long I've been here, make ONE specific ask, keep it
      warm and short.
   4. Give me a fallback ask if they refuse the number (a longer lease at
      the current rate, a repair, parking).
   
   Don't write anything that reads as a threat to leave unless I'd
   actually leave.

4. 🚗 Strip the car dealer add-ons. Photograph or paste the dealer's quote sheet and ask Claude to separate the car's price from every add-on line, flag which are optional, and write the one-line script to remove each. More than 70% of buyers purchase at least one add-on, and on a new car those add-ons average over $3,000 (CFPB, Jan 2025).
   paste into Claude

   Here's the dealer's quote sheet: [upload the photo or paste the numbers].
   
   Split it into two lists:
   1. The actual car: price, on-roads, and any genuinely unavoidable
      government charge.
   2. Every add-on line, with what it actually is in plain English, its
      typical real-world value, and whether it's optional.
   
   For each optional add-on, give me the exact one-line script to have it
   removed, the kind that's polite and hard to argue with.
   
   Then total what I'd save by removing all of them, and tell me which one
   or two are occasionally worth keeping and why.

The ones worth four figures 💼

1. 🧮 Tax prep your accountant will love. Export the financial year's transactions as CSV, upload with a paragraph about your job, and ask Claude to bucket everything into likely deduction categories with a confidence column and a receipts-to-find list. Australians claim an average of $2,956 in work-related expenses (ATO); walking in organized is how you stop missing yours. Preparation for your accountant, not tax advice.
   paste into Claude

   Here are my transactions for the financial year: [upload the CSV].
   My work: [one paragraph on what you do and how you earn].
   
   Bucket every transaction into likely deduction categories for someone in
   my line of work. Return a table with: category, total, transaction count,
   and a confidence column (high / medium / low) for whether it's likely
   claimable.
   
   Then give me:
   - a "receipts to find" list, the specific ones worth chasing by value
   - anything that looks personal and should NOT be claimed, so I don't
     walk in with it
   - the questions to ask my accountant about the medium and low confidence
     items
   
   This is preparation for my accountant, not tax advice. Flag anything
   where the rules depend on my specific circumstances rather than
   guessing.

2. 💼 Salary negotiation practice. Paste the offer letter, the job ad, your last review, and five comparable salary data points, then have Claude role-play the hiring manager pushing back on your number three times before handing you the exact counter sentence and your walk-away floor. 87% of young professionals who negotiated got at least some of what they asked for (Fidelity), yet most people never ask.
   paste into Claude

   Here's my offer letter, the job ad, my last performance review, and 5
   comparable salary data points: [paste/upload].
   
   1. Tell me honestly where my target number should sit and why, including
      whether I'm already being offered well.
   2. Now role-play the hiring manager. Push back on my counter three
      separate times, harder each round, and make me respond before you
      continue. Don't be gentle.
   3. Afterwards, grade my responses, give me the exact counter sentence
      you'd use, and my walk-away floor.
   4. List what to negotiate other than base salary if they genuinely can't
      move on the number.
