Thanks for creating something convenient for us to calculate our actual cost for the phone. I have pre-ordered the Samsung Galaxy S3 @ 1150 with a 2 year contract. According to the spreadsheet, these are my numbers.

Current Plan: $50 commitment. No data.

3GB (24 months)
RRP: $2,199.00
Device Subsidized Cost: $1,149.00
Sales Proceeds: $1,050.00
Proceeds Amortized: $43.75

Call and SMS: $15.00 (I have an average use of RM10 under Digi 1plan, RM15 is adjusted for different call/sms rates)
Data plan: $63.00
Total/Month: $78.00
New Charges/Month: $34.25

Savings/Month: $15.75
Savings/Contract :$378.00
Cost of phone: $1,821.00

I believe I have found some errors and corrected them, like my current plan information. Above are the new numbers generated from the spreadsheet. Does this mean that depending on the amount that I call and SMS, my cost of phone would vary from 1461 (ZERO Call/SMS usage), to 2661 ($50 Call/SMS usage)?

So this means, the actual cost of phone would be the amount you have paid for the phone, as well as the amount that you paid extra per month for your new plan?

In a theoretical situation, if one's main data is as such:

Original Plan: $50
New Total Charge per month: $93.75.
Contract Period: 24 months
Total amount paid over Ori.Plan for 24 months: 1050.
Price of phone: 1149

Actual cost of phone = 2199.

Is this way of thinking correct?

The formula annotations made it easy for me to understand.

So Digi really has got it covered huh, I don't think there's actually a logical way for someone to save more than 500 bucks on the phone without cutting 90% of their call/sms charges. Still I'm getting the phone cheaper I guess.

In my case. Pretty much motivates me even more to follow my friend's advice. Use data to substitute for everything, whatsapp/fb instead of messaging, skype or whatever VOIP for calls. Just minimize call charges for maximum savings. Cause every 5 ringgit/month I save on my call/sms charges I theoretically pay 100 less throughout the contract period.
