You ship a 1 kg parcel across Singapore. Depending on the courier, the cost swings by close to a dollar. At 100 orders a day, that gap is real money — this is the rate breakdown to close it.

How Much Does It Cost to Ship a Package in Singapore?
Domestic Singapore shipping typically runs SGD 1.80–2.50 for parcels under 500 g, and SGD 2.60–3.50 for a 1 kg parcel, depending on the courier and service tier. Rates rise with weight and with add-ons like same-day delivery. These are indicative ranges from published rate cards and seller-reported invoices — always confirm the exact quote in your courier’s business portal before committing volume.
Singapore has no remote-area surcharges and no inter-island complexity — every courier reaches every address. The real variable is weight, service speed, and whether you’re shipping domestically or cross-border.
Here’s how the three couriers Singapore ecommerce sellers use most often — Ninja Van, J&T Express, and SingPost — compare across five weight tiers:
| Weight | Ninja Van (Standard) | J&T Express (Standard) | SingPost (SmartPac / Parcel Post) |
|---|---|---|---|
| Up to 500 g | S$2.20–2.50 | S$2.20–2.50 | S$1.80–2.20 (SmartPac, letterbox only) |
| 1 kg | S$2.80–3.20 | S$2.60–3.00 | S$3.00–3.50 |
| 2 kg | S$3.50–4.00 | S$3.20–3.70 | S$4.00–4.80 |
| 5 kg | S$5.00–5.80 | S$4.50–5.30 | S$6.50–7.50 |
| 10 kg | S$7.50–8.80 | S$7.00–8.00 | S$9.00–10.50 |
Ranges are indicative as of Q3 2026, drawn from published rate cards and seller community reports on Ninja Van, J&T Express, and SingPost pricing. Courier rates change without notice — treat this as a planning reference, not a quote.
Shipping cross-border from Singapore adds another layer. Janio, a Singapore-based cross-border logistics platform, positions its 4PL model as consolidating multiple carriers under one contract — the company states clients typically cut cross-border logistics costs by 20–50% by replacing several separate courier relationships with one platform (source: Janio). For a 1 kg parcel to Malaysia or Indonesia, expect a meaningfully higher rate than domestic Singapore delivery once customs handling is included — get an exact figure from Janio’s own quote tool rather than assuming a flat markup.

How Is Shipping Cost Calculated in Singapore?
Courier pricing looks simple — pick a weight, get a rate — but four things move the number:
Actual weight vs. volumetric weight. Couriers bill on whichever is higher. A large, light box (think a lampshade or a stack of apparel) can get billed at its volumetric weight — length × width × height divided by a courier-set factor — rather than its true weight on a scale. If your product is bulky relative to its weight, this is usually where sellers get an invoice that doesn’t match what they expected.
Service tier. Standard next-day delivery is the baseline rate. Same-day delivery, where Ninja Van offers it for orders placed before the morning cutoff, typically adds a premium on top of the standard rate. Economy or letterbox tiers (like SingPost SmartPac) undercut standard rates but come with size and weight caps.
Route. Domestic Singapore delivery is flat-rate by weight since the whole island is treated as one zone — no remote surcharges. Cross-border shipping to Malaysia, Indonesia, or elsewhere in Southeast Asia adds customs handling and destination last-mile costs, which is the layer platforms like Janio are built to absorb into one line item.
Marketplace integration fees. If you ship through Shopee SG or Lazada SG’s integrated logistics, the platform may apply its own logistics fee on top of or instead of the courier’s direct rate. Always check whether you’re comparing the courier’s direct rate or the marketplace’s bundled logistics fee — they are not the same number.
Cash on delivery barely factors into Singapore domestic shipping — electronic payment dominates locally, unlike Indonesia or the Philippines where COD return rates are a major cost line. It matters only if you’re shipping COD orders cross-border into a market where COD is still common; in that case, budget for the return shipping cost on top of the outbound rate.
For multi-channel sellers running Shopee, Lazada, and their own store at once, shipping software such as Easyship exists specifically to pull rates from multiple carriers into one dashboard, so you’re not manually checking Ninja Van, J&T, and SingPost rate cards separately for every order.

What Does a Small Rate Difference Cost You Per Month?
A SGD 0.30–0.50 gap between couriers on a 1 kg parcel looks trivial per order. At 50 orders a day, that’s roughly SGD 450–750 a month left on the table by defaulting to the more expensive option without checking. At 200 orders a day — a mid-size Shopee or Lazada store during a campaign period — the same gap is SGD 1,800–3,000 a month. Multiply your daily order count by the per-parcel gap in the table above to see your own number.
The fix isn’t always “pick the cheapest courier for everything.” It’s matching the courier to the parcel: SingPost SmartPac for small flat items under 500 g, J&T or Ninja Van for standard parcels depending on whether marketplace integration matters more to you than the last SGD 0.20, and Janio when cross-border volume is high enough to justify consolidating carriers.

Frequently Asked Questions
How much does it cost to ship a 1 kg parcel in Singapore?
A 1 kg domestic parcel in Singapore typically costs SGD 2.60–3.50 depending on the courier, based on published rate cards for Ninja Van, J&T Express, and SingPost. Same-day delivery, where available, adds a premium above these standard rates. Rates vary by service tier, so confirm the exact figure with your chosen courier before committing to volume.
Is there a free shipping cost calculator for Singapore ecommerce sellers?
Yes. SellerShipment’s Shipping Cost Calculator estimates cost from your parcel’s billable weight, rate card, and chosen service speed. It’s free to use and doesn’t require creating an account, making it a faster first check than requesting quotes from each courier individually.
Why does my courier charge more than the weight on my scale suggests?
Couriers bill on whichever is higher: actual weight or volumetric weight, calculated from the parcel’s dimensions. A large but light box can be billed at a higher volumetric weight than its scale reading. This is common with bulky, low-density products like clothing or homeware — check your courier’s volumetric divisor before assuming your scale weight is the final number.
Does cash on delivery affect shipping cost in Singapore?
Cash on delivery has minimal impact on domestic Singapore shipping since electronic payment is the norm locally, unlike markets such as Indonesia or the Philippines. It matters mainly for cross-border orders shipped into COD-heavy markets, where a failed COD collection means paying for both the outbound and return shipment.
Which courier is cheapest for shipping small items in Singapore?
For flat items under 500 g, SingPost SmartPac’s letterbox delivery tends to be the lowest-cost option, per SingPost’s published local parcel service. For items that don’t fit the letterbox size limit, J&T Express and Ninja Van’s standard rates for sub-500 g parcels are typically close to each other — compare both against your actual box dimensions before deciding.
