Income
Managing your resources is a crucial skill in Castle Fight, knowing when to get income efficient buildings and when to apply pressure with less efficient ones is crucial. Understanding how income is earned and taxed will allow you to know how to win when you're tied on Rescue Strikes and how to not starve yourself from resources in the early game.
Lumber vs Gold
- Gold is used for everything, from buildings to items.
- Lumber is used exclusively for special buildings, legendary units and a few items
- You receive a gold bounty for killing a unit. Every unit type has different values.
- Passive income is earned from constructing buildings, value varies per building type.
- Progressive taxation is applied exclusively to passive income
- You get your income every n seconds, where n is a value set by the game mode.
- Non-specialbuildings give 100% (75% for siege) of their gold cost back as lumber.
- Items do not give any income or lumber. Bounty still applies to units killed by items.
Passive income formula
Every time you build something, your income increases based on the building's type and its gold cost. For example a 100g normal building will give 2 gold income but a 100g tower, only 0.8 gold income. Keep in mind those values are before-tax.
| Building Type | Income Percentage |
|---|---|
| Normal Unit Buildings | 2.0% |
| Siege Unit Buildings | 1.8% |
| Spell Buildings | 1.2% |
| Enemy-Target Spell Buildings | 0.9% |
| Tower Buildings | 0.8% |
Taxes
Castle Fight uses a progressive taxation system to avoid exponential growth of income. Every bracket of income is a subject to higher, separate taxation up to a limit of 80%.
- Taxation increases by 10% per bracket, the size of it depends on the tax mode
- The brackets for normal/medium/high mode are 25/20/12.5 income, respectively
- The brackets are independent, at 50 income in normal taxes, only 25-50 is taxed.
- Taxes don't take gold from you, they only lower the amount of income you receive.
| Income Range | Tax Penalty | Effective Gain |
|---|---|---|
| 0–24 | 0% | Full value |
| 25–49 | 10% | 90% of value |
| 50–74 | 20% | 80% of value |
| 75–99 | 30% | 70% of value |
| 100–124 | 40% | 60% of value |
| 125–149 | 50% | 50% of value |
| 150–174 | 60% | 40% of value |
| 175–199 | 70% | 30% of value |
| 200+ | 80% (max) | 20% of value |
Income vs Tax Brackets
This interactive chart shows you the real income value you receive for each point of untaxed income. It does take into account different brackets and different modes, showing both individual values and the curve of the chart for each one.
Example:
You have built buildings worth 100 untaxed income in Medium Taxes (-mt) mode:
- 0-20 - this bracket is not taxed at all
- 20-40 - this bracket is taxed for 2
- 40-60 - this bracket is taxed for 4
- 60-80 - this bracket is taxed for 6
- 80-100 - this bracket is taxed for 8
- The values are added up for a total of 20, this means the real income you receive here is 80 gold.
