How long does it usually take to save for a family holiday?

Most Australian families save for an overseas family holiday over 9 to 18 months. A AUD$12,000 Bali trip works out to about AUD$153 per week saved over 18 months, AUD$231 over 12 months, or AUD$462 over 6 months. The right timeline is whichever weekly number you can sustain without it dominating your monthly budget.

Can a family save for an overseas holiday in 6 months?

Yes, but only if the weekly target is realistic given your existing cash flow. A AUD$12,000 Bali trip in 6 months is AUD$462 per week. A AUD$17,000 Japan trip in 6 months is AUD$654 per week. Those are big numbers — achievable for some families, unrealistic for most. If the 6-month weekly target is more than 15% of your take-home pay, push the trip out to 12 or 18 months.

How much should you save per week for a family holiday?

There is no single right number. The honest formula is: total trip cost divided by the number of weeks until departure equals your weekly target. AUD$12,000 over 52 weeks is AUD$231 per week. AUD$17,000 over 78 weeks (18 months) is AUD$218 per week. The right starting point is your destination total, not someone else's weekly average.

What's the minimum time you need to save for a family holiday?

Three to four months is the practical floor for an overseas family trip. Below that, the weekly savings target becomes uncomfortable for most households, and you also start running into booking deadlines — flights and accommodation usually need to be paid in full 4 to 8 weeks before departure. Domestic trips and short-haul beach trips (Fiji, Bali) can sometimes work on shorter runways.

Does it take longer to save for a family holiday with kids?

Yes, usually. Adding two children to a trip roughly doubles flights, increases accommodation (one room becomes two), and adds activity costs. The same trip that costs AUD$8,000 for two adults often costs AUD$15,000–17,000 for a family of four. Saving over 12 to 18 months is often the only realistic way to keep the weekly number sustainable. The 'save earlier' advice matters even more once kids are in the picture.

How do you save for a family holiday faster?

There are three honest levers: trim the trip (shorter, cheaper destination, fewer activities), automate the savings (the single biggest predictor of hitting target is whether transfers run on pay day automatically), and add a one-off boost (tax return, work bonus, sale of unused gear). The compounding effect of starting earlier usually beats any of these — a trip 18 months out is genuinely easier to save for than the same trip 9 months out.

How Long Does It Take to Save for a Family Holiday?

This is the question every family asks first. Before they ask how much, before they ask where, before they argue about whether the budget should include spending money or not. They ask: how long is this actually going to take?

The good news is the answer is short and concrete. The honest version, with real numbers, is what this post is about.

If you want the broader savings system, how to save for a family holiday walks through the full step-by-step. The weekly savings target guide is the deep dive on the per-week number. This post sits in front of both — it's the back-of-envelope timeline calculation that tells you whether the trip is a 6-month plan, an 18-month plan, or a "we need to push this out" plan.

The Core Formula

There's only one formula and it's simple:

Total trip cost ÷ weeks until departure = weekly savings target

That's the whole calculation. Every other piece of savings advice is just dressing on this number. A AUD$12,000 trip 52 weeks away is AUD$231 per week. The same trip 78 weeks away is AUD$153 per week. The same trip 26 weeks away is AUD$462 per week.

The trip total doesn't change. The weekly target changes by a lot depending on how long you give yourself.

If your destination isn't here, the formula still applies — pull the headline number from the matching guide and divide.

How to Pick Your Timeline

Look at the weekly number and ask one question: what percentage of household take-home pay is this?

A useful rule of thumb:

Under 10% of weekly take-home pay → comfortable. The trip won't dominate your month-to-month budget. Most families can sustain this without changing how they live.
10–15% → a stretch. Workable, but you'll feel it. You'll probably need to cut a couple of small categories (takeaway, subscriptions, weekend extras) to hit the target consistently.
15–20% → uncomfortable. Possible if you're disciplined and the trip is short, but most families won't sustain this for more than 4–6 months without slipping.
Over 20% → unsustainable. The plan will fail somewhere in the middle. Push the trip out, trim the trip, or both.

The mistake most families make is picking the shortest timeline they can theoretically afford and then quietly missing it. The better move is picking the longest timeline that still gets you to the trip you want — smaller weekly numbers, bigger buffer, less stress when life intervenes.

Why Starting Earlier Compounds

Starting earlier doesn't just lower the weekly number. It also unlocks a few quiet bonuses:

Interest works in your favour. A high-interest savings account at current Australian rates earns roughly 4–5% per year. On AUD$12,000 saved over 18 months, that's AUD$300–$450 of interest. It's not life-changing, but it's effectively a discount on the trip. Saving over 6 months instead of 18 months loses you most of that interest.

Booking flexibility goes up. When you've got 18 months of runway, you can book flights at the moment they hit the price you want, not when the calendar forces you to. Same with accommodation — you can wait for the right hotel deal instead of taking what's available six weeks out.

Cash flow shocks become survivable. Cars break down. Boilers die. Tax bills land bigger than expected. With a 6-month timeline, one bad month can wipe out the plan. With an 18-month timeline, you can pause for a few weeks and catch up later without the trip falling apart.

The conversation gets easier. If you're saving with a partner, smaller weekly numbers are less politically charged. AUD$150 per week shared between two earners is a small ask. AUD$500 per week feels like a battle every time pay lands.

The Honest Floor: How Short Can You Go?

The shortest realistic timeline for an overseas family trip is about 3 to 4 months, and even that requires two things to be true:

The weekly target works for your cash flow
You're booking late enough that flights and accommodation are still available at non-emergency prices

For domestic trips and short-haul beach trips (Bali, Fiji, Vanuatu), 8–12 weeks can work because the booking lead time is shorter and the cost is lower. For Japan, Europe, the US, anywhere with a 14+ hour flight, the booking calendar starts to push back. Flights are usually paid in full 4–8 weeks before departure. Accommodation deposits land 8–12 weeks out. If you start saving 12 weeks before the trip, you're already in payment territory before you've finished saving.

The practical advice: if the trip is more than AUD$10,000 and more than 6 hours of flight time, give yourself at least 6 months. Twelve is better.

What Slows Families Down

A few patterns show up over and over in families who set a timeline and miss it:

No automatic transfer. If the saving depends on remembering to move money each week, it will fail. Set up a recurring transfer on pay day and stop relying on willpower.
No dedicated account. Money sitting in the everyday account gets spent. A separate, named account ("Japan 2027" or similar) is one of the highest-leverage 30-second decisions you can make.
Total in someone's head. If the trip cost only exists in one person's head, the other partner can't engage with it. Get it written down — even a note on the fridge — and the savings target stays real.
No re-pacing when things change. Trip plans always change. Hotel options change. Flight prices shift. Activities get added. If you're not re-pacing the weekly target when the total moves, you'll drift off course without realising.

The third and fourth points are exactly the gap SaveToRoam exists to fill. You enter the trip — flights, accommodation, the lot — and the platform calculates the weekly target. When the trip changes, the target updates automatically. You can re-pace the plan without re-doing the maths.

Pick a Number, Set the Transfer

Here's the action this whole post is leading to:

Pick a destination and a rough total from the cost guides
Pick the longest timeline that still gets you there
Divide the total by the weeks
Set up an automatic transfer from your everyday account to a dedicated savings account on pay day, equal to the weekly target

That's the whole thing. The trip is the prize. The savings are just the route — and now you know exactly how long the route takes.
