Only just seen yr message.
Pretty sure I left that spreadsheet back in London so forget it.
Been in Bali on & off for 7 months now so maybe my actual expenditure to date will assist.
Main Items =
New 500 m2 house w/pool, & staff +/-$1,000 per mnth
House Construction – Rp2-3m per m2 so 400/500m2 house w pool, landscaping etc = +/-$180,000
Land – Rp5 – 100/200m+ per Are. 1 Are = 100m2. 40 Are = 1 acre.
Car - beaten up pile of crap Rp2.5m per mnth - 2 yr old Kijang Rp3m per mnth
Petrol - nothing
Medical Insurance - $1,000 for Akari & I AFTER 45% discount for $1,000 ($1,600 ??) excess
Food in local markets - nothing
Food in expat delis - generally pricey but not crazy
Restaurants - cheap
Books - expensive
Vino - ditto
CDs/DVDs – nothing
Diving - $45 for 2 dives, cheaper in Malaysia
Visas - expensive
Regional Air Travel - cheap e.g. DPS to Jakarta = Rp 280,000; Jakarta to Malaysia via Air Asia = nothing

Conclusion - charming, inexpensive place to live. Lots of negatives but many more positives. You can live like an Old Testament hermit on nothing or follow a swanky Monte Carlo lifestyle for megga bucks like all those gin swillin’ golf club swinging losers in Nusa D.
It's up to you.
