How to Calculate Furniture Storage Costs: The Short Answer
Working out furniture storage costs comes down to one chain: add up the volume of your belongings, match that volume to a unit size, then multiply the monthly rate by the number of months you need.
Most Australian storage operators publish indicative monthly rates by unit size. Those figures shift with location, access type, and how long you stay, so treat any online number as a starting point, not a quote.
Here’s the formula we recommend:
Total cost = (monthly rate x months) + once-off costs + insurance + packing materials
Below, we’ll walk through each step so you can build a realistic number for your own home.
The monthly rate is only part of your furniture storage costs. Once-off charges and insurance often add a meaningful amount in the first month, so always ask for a full itemised quote before you book.
Step 1: Build an Inventory List of Your Furniture and Household Items
Start with a written inventory before you measure anything. An inventory list turns a vague “we’ve got a lot of stuff” into numbers you can add up.
Walk through your home and note every item you plan to store. Include the bulky things people forget: the spare fridge in the garage, the treadmill, the outdoor setting.
Go Room by Room: Bedroom, Lounge, Dining Room and Kitchen
Splitting the job by room keeps you organised and stops double-counting.
- Bedroom: bed frame, mattress, bedside tables, wardrobe contents, dresser
- Lounge: sofa, armchairs, coffee table, TV unit, bookcase
- Dining room: dining table, 4-6 chairs, buffet, display cabinet
- Kitchen: fridge, microwave, boxes of cookware and crockery
Mark anything you’re unsure about keeping. Those items feed into the store-versus-sell decision later.
Step 2: Measure Length, Width and Height to Work Out Cubic Metres of Furniture
Volume is the number that matters. Measure each item’s length, width and height in metres, then multiply the three together to get cubic metres of furniture.
A sofa measuring 2.1m long, 0.9m deep and 0.8m high works out to about 1.5 cubic metres. Do this for every large item and add the totals.
Smaller items are easier to group. Pack boxes, then estimate the volume of the stack rather than each box.
Approximate Space Needed for Common Household Items
These figures are rough guides for planning. Real volumes vary with your furniture’s exact dimensions.
| Item | Approximate volume | Notes |
|---|---|---|
| Three-seater sofa | 1.4-1.7 m³ | More if reclining |
| Queen bed and mattress | 1.8-2.2 m³ | Dismantled frame saves space |
| Dining table and 4-6 chairs | 1.5-2.0 m³ | Stack chairs on the table |
| Fridge | 0.6-0.9 m³ | Upright, doors taped shut |
| Wardrobe | 1.2-1.8 m³ | Flat-pack if possible |
| Bookcase | 0.5-0.9 m³ | Remove shelves if it helps |
Photograph each item as you measure it. If anything is damaged in transit, your photos and inventory list give you a clear record for an insurance claim.
Step 3: Use a Storage Unit Size Guide to Match Volume to Unit Size
A storage unit size guide converts your total volume into a unit that actually fits. Book too small and you’ll be paying for a second unit within a week.
Unit sizes are quoted in square metres of floor area, but what matters is the cubic capacity once you stack. Most units have generous ceiling height, so stacking boxes and lighter items vertically can cut the size you need.

Matching Home Size to Unit Size
Use this as a starting point, then adjust for how much you’re actually storing.
| Home size | Typical volume | Suggested unit |
|---|---|---|
| Studio or single room | 3-5 m³ | 1.5m² to 3m² |
| One-bedroom unit | 6-9 m³ | 3m² to 6m² |
| Two-bedroom home | 10-15 m³ | 6m² to 10m² |
| Three-bedroom home | 16-25 m³ | 10m² or larger |
If you’re storing a caravan, boat or jet ski alongside household goods, you’ll need a dedicated space rather than a standard unit, our caravan storage in Bunbury and jet ski storage in Bunbury are built for exactly that.
Step 4: What Drives Monthly Storage Rental Prices
Monthly storage rental prices move with a handful of factors you can plan around.
- Unit size: the biggest driver. Larger units cost more per month.
- Location: metro and high-demand areas generally cost more than regional sites.
- Access type: drive-up access usually costs more than walk-in.
- Climate control: protects furniture from humidity and temperature swings, and adds to the rate.
- Length of stay: longer commitments often attract better rates than short-term bookings.
One-Off Costs to Add Before You Sign
The monthly rate is not your whole bill. Budget for these extras:
- Admin fee: a one-time setup charge on new agreements
- Lock: buy one or bring your own
- Goods insurance: covers your belongings while stored
- Packing materials: boxes, tape, bubble wrap, furniture covers
- Removalist or transport: moving your items to the facility
Skipping goods insurance to save money is a false economy. If a fire or flood damages your furniture, you carry the full replacement cost yourself.
Step 5: Run the Numbers in a Furniture Storage Cost Calculator
A furniture storage cost calculator turns your volume estimate into a total. You can build a simple one yourself with the formula below.
Total = (monthly rate x months) + admin fee + insurance + packing materials + transport
If you’d rather not build your own, use a space calculator to estimate volume, then confirm current rates on our website.
Worked Example: A Two-Bedroom Home (Illustrative)
This example is illustrative only. Your actual figures will differ based on location, facility, and the exact items you store.
Say you’re storing a two-bedroom home for three months. Your inventory comes to roughly 12 cubic metres, which points to a 6m² to 10m² unit. Here’s how the numbers might stack up:
| Cost component | Assumption | Amount (AUD) |
|---|---|---|
| Monthly rate | 6m² unit, metro area | $280 per month |
| Monthly rate x 3 months | $840 | |
| Admin fee | One-off at sign-up | $30 |
| Goods insurance | $15 per month x 3 | $45 |
| Packing materials | Boxes, tape, covers | $120 |
| Transport | One removalist trip | $350 |
| Total | $1,385 |
That works out to roughly $462 per month all-in for the first three months, compared with the $280 headline rate. The gap is the once-off costs and insurance that many people forget to budget for.
If you stored for six months instead, the monthly rate might drop to $260, but you’d add three more months of rent and insurance.
Ask for a full itemised quote before you book. A quote that lists the monthly rate, admin fee, insurance premium, and any lock or access charges lets you compare like-for-like between facilities.
Quick Reference: Monthly Cost Ranges by Unit Size
These indicative ranges are for planning only. Actual pricing varies by location, facility features, and current promotions.
| Unit size | Typical monthly range (AUD) | What it holds |
|---|---|---|
| 1.5m² | $90-$150 | Small wardrobe, boxes, a few small items |
| 3m² | $150-$220 | Studio or single room of furniture |
| 6m² | $220-$320 | One-bedroom unit or a two-bedroom home packed tightly |
| 10m² | $320-$450 | Two to three-bedroom home |
Use these as a starting point, then confirm current rates with the facility you’re considering.
Store or Sell and Replace? Weighing the Trade-Off
Storing usually wins when your furniture is good quality, you’ll need it again soon, or replacing it would cost more than storing it. Selling and replacing makes sense when you’re storing long-term, the items are worn, or you’re paying to keep things you’ll never use again.
But the decision gets clearer when you put numbers on both sides.

A Simple Framework
Ask yourself three questions:
- How long will you store? Short-term (under six months) usually favours storing. Long-term (over twelve months) often favours selling and replacing.
- What’s the replacement cost? Add up what it would cost to buy equivalent items new or second-hand. If that total is less than your storage costs over the same period, selling may win.
- How much do you actually need? If you’re storing items you haven’t used in a year, the storage cost is pure loss.
Running the Numbers: A Two-Bedroom Example (Illustrative)
This example is illustrative only. Your figures will differ.
Say you’re deciding whether to store a two-bedroom home’s furniture for twelve months or sell it and replace later.
Option A: Store for 12 months
| Cost component | Amount (AUD) |
|---|---|
| Monthly rate (6m² unit) | $260 x 12 = $3,120 |
| Admin fee | $30 |
| Goods insurance | $15 x 12 = $180 |
| Packing materials | $120 |
| Transport to storage | $350 |
| Transport out of storage | $350 |
| Total | $4,150 |
Option B: Sell and replace
| Cost component | Amount (AUD) |
|---|---|
| Sale proceeds (estimated) | -$1,500 |
| Replacement cost (equivalent items) | $4,500 |
| Transport or disposal of sold items | $200 |
| Net cost | $3,200 |
In this example, selling and replacing costs less over twelve months. But if you only needed storage for three months, the storage total would drop to around $1,385, making storing the cheaper option.
When Storing Makes Sense
- You’re renovating and will move back in within a few months.
- You’re between homes and need a short-term solution.
- Your furniture is high-quality or has sentimental value.
- Replacement costs would exceed storage costs for your timeframe.
When Selling and Replacing Makes Sense
- You’re storing for more than a year.
- The items are worn, outdated, or easily replaced.
- You’re paying to store things you rarely use.
- You’d rather start fresh than pay to keep old items.
Don’t forget the hidden costs of selling: listing fees, time spent photographing and responding to buyers, and the hassle of coordinating pickups. These aren’t dollar amounts on a spreadsheet, but they matter.
A Quick Rule of Thumb
If your storage costs over the planned period exceed 50% of what it would cost to replace the items, selling and replacing is usually the better financial move.
Run the numbers both ways before you decide. A furniture storage cost calculator can help you estimate the storage side, and a quick online search will give you a sense of replacement costs for similar items.
Conclusion
Getting furniture storage costs right comes down to honest measurement and a full list of charges, not just the monthly rate. Most people underestimate their volume and forget the once-off costs, then wonder why the first invoice looks bigger than expected.

Frequently Asked Questions
How much does it cost to store furniture per month in Australia?
Monthly furniture storage costs depend on unit size, location, access type and how long you stay. Regional areas usually cost less than capital cities. Urban Self Storage publishes current rates on its website, so you can get an exact figure for your chosen unit before booking.
What size storage unit do I need for a two-bedroom house of furniture?
A two-bedroom home typically needs a 6m² to 10m² unit, depending on how much you keep and whether you stack boxes. Use a storage unit size guide to match your measured volume: a queen bed, sofa, dining setting, fridge, wardrobes and boxes usually total around 10 to 15 cubic metres. Measure your actual items first, then round up to the next unit size so you are not paying for space you cannot use.
What factors affect self storage prices?
The main storage unit pricing factors are unit size, location (city versus regional), access type (drive-up versus internal), climate-controlled storage, length of stay and whether you add goods insurance. Longer stays sometimes attract a lower monthly rate, while frequent access or premium locations push costs up. One-off items such as an admin fee, lock, packing materials cost and removalist transport also affect your total outlay, so factor these in before comparing quotes.
Is it cheaper to store furniture or sell and replace it?
It depends on how long you store and what the items are worth. Short-term storage of three to six months is often cheaper than selling good furniture at a loss and buying replacements later. For long-term storage beyond a year, add up your monthly storage rental and compare it against the resale value of your items plus the cost of buying new ones. High-value pieces usually justify storage; low-value, bulky items often do not.
