What does a 1300 or 1800 number cost? Every fee explained

A 1300 or 1800 number makes a business look established. It is easy for customers to remember, and it lets you route calls wherever your team is.
The costs can seem confusing at first, because they come in three parts. This guide explains each fee, then shows what a typical month costs.
The short version
A 1300 or 1800 number through NOIZE has three costs: number hosting and line rental at $50 a month, IVR set-up and management at $25 a month, and call usage at $0.45 a minute. Hosting and IVR stay the same each month. Call usage goes up and down with how many calls you take. At 20 minutes a month the total is $84. At 250 minutes it is $187.50.
The three fees
01Number hosting and line rental: $50 a month
Every 1300 or 1800 number has to be hosted and maintained on a phone network. This fee covers:
- The ongoing service charge that keeps your number active
- Line rental for the connection
- Technical support and system maintenance
Think of it as the base cost of keeping the number running.
02IVR set-up and management: $25 a month
IVR stands for interactive voice response. It is the menu callers hear: "Press 1 for sales, press 2 for support". This fee covers:
- The ongoing service charge for the IVR
- Setting up call routing and menu prompts
- Ongoing maintenance, including one change each month
03Call usage: $0.45 a minute
Calls are charged from the moment they connect until they end. The rate is $0.45 a minute, whether the caller is on a landline or a mobile.
What a month costs
| Monthly call volume | Hosting | IVR | Call usage | Total |
|---|---|---|---|---|
| 20 minutes | $50 | $25 | $9 | $84 |
| 50 minutes | $50 | $25 | $22.50 | $97.50 |
| 100 minutes | $50 | $25 | $45 | $120 |
| 250 minutes | $50 | $25 | $112.50 | $187.50 |
How to budget for it
Hosting and IVR are fixed, so they are easy to plan for. Call usage grows with the business. The more calls you get, the higher that line will be.
Check your call volume each month to see how usage turns into cost. If calls rise because marketing is working, the extra cost usually means extra enquiries coming in.

Common questions
What is the difference between a 1300 and an 1800 number?
With an 1800 number, calls are free for the caller and the business pays for the call. With a 1300 number, the cost is usually shared. The monthly fees above apply to both.
Do mobile calls cost more?
No. Call usage is $0.45 a minute whether the caller is on a landline or a mobile.
Can I change my phone menu later?
Yes. One change a month is included in the IVR fee.
Do I need an IVR?
Not always. An IVR helps once calls need to reach different people or teams. A sole trader may not need one.
