Boost Calculation Guide

	Effective August 7, 2014 Negative Boost Effects On The Opposite Element Were Removed

Calculating Earnings Summary

The boosted earning rate can be calculated using the below equation:

Boosted Income = (Base Income x (1 + 0.3 * Number of boosts))

When multiplying if there is a decimal in your product round it up the next whole number.

Example: 202.27 would become 203

Number of Positive Boosts	Multiply The Earning Rate Without Boosts By
0	1.00
1	1.30
2	1.60
3	1.90
4	2.20

Calculating Earnings With Positive Element Boosts

Boosts each provide an increase of 30% to the earning rates of dragons of the same element that are housed on the island that the boost is placed on. Depending on the boost and dragon placement, a dragon's earnings rates can be affected in a positive way.

Please refer to the Boosts page, as well as each boost's individual page, for more details.

Boosts do not affect epic dragons without primary elements (besides monolith dragons or any of the gemstone dragons at this time.

To calculate the earning rate of a dragon, the player will need to determine how many boosts are affecting that dragon. Then, the player will need to add that amount from his/her dragons' earnings. The effects of one positive boost on a dragon with a base earning rate of 100 would be calculated as:

100 + (100*30%) = 130

If a dragon's base earning rate is 100, and was then affected by two positive boosts, the calculation would be:

100 + 2*(100*30%) = 160

If a dragon's base earning rate is 100, and was then affected by three positive boosts, the calculation would be:

100 + 3*(100*30%) = 190

If a dragon's base earning rate is 100, and was then affected by four positive boosts, the calculation would be:

100 + 4*(100*30%) = 220

The generic formula to follow is:

The player simply needs to place the appropriate number of positive boosts into the formula for their given situation.

Boosted Income = (Base Income x (1 + 0.3 * Number of boosts))

Note, multiplying a number by 1.3 is the same as adding on 30%.

When multiplying if there is a decimal in your product round it up the next whole number.

Rounding Ranges

Once a dragon's displayed earn rate goes over 900 DragonCash per minute, a dragon's earn rate will get rounded up to cerain values depending on how much they earn.

Range of Displayed Rates	Rounded To
900-999	1,000
1000-1,199	1,200
1,200-1,499	1,500
1,500-1,999	2,000
2,000-2,999	3,000

Example: A Tien Dragon's base earning rate at level 20 is 992, if affected by four positive boosts, the calculation would be:

992 * 4*(100*30%) = 2,182, which gets rounded up to 3,000.

Outdated Calculating Method With Positive and Negative Boosts

Boosts each provide an increase of 20% to the earning rates of dragons of the same element, and a decrease of 20% to the earning rates of dragons of the opposite element, that are housed on the island that the Element Boost is placed on. Depending on Boost and dragon placement, a dragon's earnings can be affected in both positive and negative ways.

Please refer to the Boost page, as well as each individual boost's page, for more details.

Boosts do not affect the Epic Dragons or any of the Gemstone Dragons at this time.

To calculate the earning rate of a dragon, the player will need to determine how many Element Boosts are affecting that dragon, and whether the boosts are positively or negatively affecting the dragon. Then, the player will need to add or subtract that amount from your dragons' earnings. The effects of one positive OR one negative boost would be calculated as:

100 + (100*20%) = 120

100 - (100*20%) = 80

It is important to note that the effects of Boosts are cumulative, meaning that the percentages are calculated in succession. If a dragon's base earning rate is 100, and was then affected by two positive boosts, the calculation would be:

100 + (100*20%) = 120 ---> 120 + (120*20%) = 144

Another important fact is that it doesn't matter if the positive Boosts are calculated first and then the negative Boosts are calculated from that total or vice versa.

What matters is that one positive Boost does NOT simply cancel out one negative Boost. We will use the previous example again to illustrate calculating two positive Boosts and one negative Boost:

100 + (100*20%) = 120 ---> 120 + (120*20%) = 144 ---> 144 - (144*20%) = 115.2 (round to 115)

Two positive Boosts and two negative boosts would be calculated as:

100 + (100*20%) = 120 ---> 120 + (120*20%) = 144 --->. 144 - (144*20%) = 115.2 ---> 115.2 - (115.2*20%) = 92.16 (round to 92)

The generic formula to follow is:

Dragon's base earning rate + positive Boost #1 + (positive Boost #1*positive Boost #2) - negative Boost #1*(positive Boost #1*positive Boost #2) - negative Boost #2*(negative Boost #1*positive Boost #1*positive Boost #2) = actual earning rate

The player simply needs to place the appropriate number of positive and negative boosts into the formula for their given situation.

(gpm x 1.2^y) x 0.8^z

gpm = dragoncash per minute with no boosts

y = number of positive boosts

z = number of negative boosts

Note, multiplying a number by 1.2 is the same as a positive boost and multiplying by 0.8 is the same as a negative boost.

Note, y and z are the exponents so if y equals 2 then the gpm would be multiplied by 1.2 x 1.2 or 1.44 and if z equals zero then the (gpm x 1.44) would be multiplied by 1 (because anything to the power of zero is 1)

For gpm, y and z just input the numbers in your situation.
