Silo to Harvester Ratio and Cost Guidelines

Calculating the rate of return is the cost of the building to be upgraded compared to the projected production of the building. How this calculation is done is variable depending on the inputs, base layout, account needs, etc. General guidelines need to be clear based on what the player is doing. For instance, during PVP, beginning of a server, etc all impact what the level ratios are for a silo to harvester.

Ratios

As of the 20.1 Update release the following cost and production ratios are valid (The games resources are based on a power/log base progression):

Cost increase is 1.32 starting from level 12+ base costs
Production increase is 1.25 starting from level 12+ base costs
Harvester power requirement is 75% of tiberium cost
Silo power requirement is 25% of tiberium cost
Accumulator power requirement is 25% of tiberium cost
Powerplant power requirement is 10% of tiberium cost
Unique Buildings power requirement is 25% of tiberium cost

General Equation to Determine Cost or Production of a Facility

Cost: 48,000*(1.32)^(Level of Building -12)
Production: Production #*(1.25)^(Level of Building-12)

Starting Costs of Buildings (Level 12)

Silo: 48,000 Tiberium | 12,000 Power
Harvester: 48,000 Tiberium | 36,000 Power

Starting Resource Production of Facilties (Level 12)

Harvester:
Continuous – 710 resource per hour
Package – 2,360 resource per hour
Total: 3,070 resource per hour

Silo (Per Harvester):
Continuous: 710 resources per hour
X2: 1,420 per hour
X3: 2,130 per hour
X4: 2,840 per hour
X5: 3,550 per hour
X6: 4,260 per hour

Harvester Specific Calculation Considerations:
Package Production of harvesters should not be ignored. To take into consideration package production and its impact on rate of return calculations, apply a adjusting factor based on the assumption of how often a base will move. Since harvesters after level 12 produce packages every 6 hours the calculation is simple:
0 moves a day: 100% of package production
1 move a day: 75% of package production
2 moves a day: 50% of package production
3 moves a day: 25% of package production
4 moves a day: 0% of package production

Harvester:
@ 0 move per day: 3,070 per day
@ 1 move per day: 2,480 per day
@ 2 moves per day: 1,890 per day
@ 3 moves per day: 1,300 per day
@ 4 moves per day: 710 per day

Rate of Return Calculations
There are 2 distinct methods with which to calculate the underlying return on cost methodologies:
• Tiberium cost weighted rate of return; or
• Total rate of return (power + tiberium costs)
After determining the base method above, some prefer to weight continuous production over package production. A player needs to know when to use which method, and then stick to it especially if package production plays a significant factor.

Tiberium weighted:

Silos:
1-Touch silo: 48,000 tiberium / (710*1) = 67.60 hours
2-Touch silo: 48,000 tiberium / (710*2) = 33.80 hours
3-Touch silo: 48,000 tiberium / (710*3) = 22.54 hours
4-Touch silo: 48,000 tiberium / (710*4) = 16.90 hours
5-Touch silo: 48,000 tiberium / (710*5) = 13.52 hours
6-Touch silo: 48,000 tiberium / (710*6) = 11.27 hours

Harvesters:
@ 0 move per day: 48,000 Tiberium / 3,070 per day = 15.63 hours
@ 1 move per day: 48,000 Tiberium / 2,480 per day = 19.53 hours
@ 2 moves per day: 48,000 Tiberium / 1,890 per day = 25.39 hours
@ 3 moves per day: 48,000 Tiberium / 1,300 per day = 36.90 hours
@ 4 moves per day: 48,000 Tiberium / 710 per day = 67.60 hours

Total:

Silos:
1-Touch silo: 48,000 tiberium +12,000 Power / (710*1) = 84.51 hours
2-Touch silo: 48,000 tiberium +12,000 Power / (710*2) = 42.25 hours
3-Touch silo: 48,000 tiberium +12,000 Power / (710*3) = 28.17 hours
4-Touch silo: 48,000 tiberium +12,000 Power / (710*4) = 21.13 hours
5-Touch silo: 48,000 tiberium +12,000 Power / (710*5) = 16.90 hours
6-Touch silo: 48,000 tiberium +12,000 Power / (710*6) = 14.08 hours

Harvesters:
@ 0 move per day: 48,000 Tiberium +12,000 Power / 3,070 per day = 27.36 hours
@ 1 move per day: 48,000 Tiberium +12,000 Power / 2,480 per day = 33.87 hours
@ 2 moves per day: 48,000 Tiberium +12,000 Power / 1,890 per day = 44.44 hours
@ 3 moves per day: 48,000 Tiberium +12,000 Power / 1,300 per day = 64.62 hours
@ 4 moves per day: 48,000 Tiberium +12,000 Power / 710 per day = 118.31 hours

Based on the above a few guidelines can be determined for Silo / harvester level ratios below. The number represents the silo level compared to the harvester level.
