There has been a lot of talk about how Infinia points are valued at 85.7p. However, couldn't find any details about Edge miles or edge rewards points value in the same context. Also, even for Infinia the 85.7p is applicable only if redeemed for flights, it drops if we redeem it for hotels. Thought of creating this thread to explain all these.
Infinia
1. Why 85.7p?
If you're booking a flight for 1500 rupees through smartbuy, you'll get 1500/150*5*5 = 250 points. 250/1500 = 16.66. You are getting 16.66% RPs. Now, if you're redeeming 1500 points for a flight(assume that 1500 is < 70% of the ticket cost so that you can redeem 1500 pts), you're losing out on 250 points. So effectively, to buy 1500 rupee worth of the ticket, you're using 1500+250=1750 points, so each point is worth about 1500/1750=85.7p.
For simplicity's sake, let's do the calculation on a 100 rupee basis. For 100 rupees spent on a flight ticket, you'll get 16.66 points, so while redeeming 100 points, you'll effectively spend 100 points and forsake 16.66 points, so each point is valued at 100/116.66 = 85.7p
So, we can say that 5x rewards on Infinia is equivalent to a 14.28% reward rate. This calculation assumes that you're redeeming it for flights.
2. How much each RP is worth if used for hotel bookings?
For 100 rupees spent on hotels, you'll get 33.33 points, so while redeeming 100 points, you'll effectively spend 100 points and forsake 33.33 points, so each point is valued at 100/133.33=75p.
Now, this assumes that you haven't breached the 15000 accelerated RPs limit that you can reach per month. If you're buying anything above that limit, effectively, all your reward points are worth 96.77p each because you aren't forsaking 16.66 or 33.33, but only base reward rate of 3.33%.
To breach the limit of 15000 accelerated reward points, the following is the calculation.
For 5x categories, x base and 4x accelerated, (x/150)*5*4 = 15000 => (x/30)*4 = 15000 => x = 112500
For 10x categories, x base and 9x accelerated, (x/150)*5*9 = 15000 => (x/30)*9 = 15000 => x = 50000
For a mix of 5x and 10x, let's take f as money spent on 5x and t as money spent on 10x categories, so (f/150)*5*4+(t/150)*5*9 = 15000 => f/30*4+t/30*9 = 15000 => 4f+9t=450000.
Atlas
Similarly, let's take Atlas miles calculations. I'm calculating assuming only Accor in mind. People might be able to get much greater value out of it. I'm doing this because I use edge miles and rewards only with Accor.
For 100 rupees spent, you get 2 miles which converts to 4 accor points. Each accor point is worth Rs. 1.82 now, let's assume Rs. 1.8, so for every 100 spent, you get Rs.7.2 worth accor points. However, similar to how we had to forsake accelerated reward points in Infinia for redeeming points, here also, For every 100 rupee spent in accor hotels, we'll have to forsake 5 partner miles, ie, 10 accor points, that is Rs. 18. Effectively, you're spending 100 rupees worth of points and forsaking 18 rupees worth of points to get 100 rupees worth in value. So, in % terms, it comes to 100/118 = .84. This means, 7.2% reward rate of Atlas via accor translates to 7.2*.84 = 6.048%. If milestone benefits are calculated for 750000 spends, we'll get 15000 base points, 5000 milestone points and 2500 points for paying 5900 fee. Totally, 22500 points, which translates to 45000 accor points. At Rs 1.8 each, value is 81000. If we take .84 of this, we get 68040, subtracting 5900 fee paid, we get 62140. So effective reward rate is 62140/750000=8.28%.
Of course, for people who know how to play the airmiles game, this calculation will be completely different. Unfortunately, I don't know much about it. This is what I'm comfortable with and I optimize my spends based on this.
