Why Every Evony Player Eventually Needs an RSS Calculator
You've hit that wall before. You queue up a building upgrade, watch the resource cost pop up, and realize you're short 400,000 ore with no idea how long it'll take to close the gap. That's the moment most players start hunting for an Evony resource calculator instead of eyeballing their warehouse and hoping for the best.
This guide walks through how to actually plan your RSS (resources) using our calculator, what it accounts for, and how to farm smarter instead of just farming more.
What an Evony Resource Calculator Actually Does
An Evony resource calculator takes your current stockpile, your production rate per hour across food, lumber, stone, ore, and gold, and the cost of whatever you're planning next: a building upgrade, a research tier, or a troop training queue. It then tells you how much time you need, or how many additional gathering marches you should send out, to hit that number.
This matters because Evony's resource requirements scale hard. A City Hall upgrade at level 20 doesn't cost what it did at level 10. It costs dramatically more, often across all five resource types at once, and your production rate rarely scales at the same pace unless you've been actively investing in it.
Without a planning tool, most players fall into one of two habits: over-farming resources they don't need yet, which wastes march time and exposes troops to attacks, or under-farming and hitting a wall mid-upgrade with nothing queued behind it.
The Five Resources You're Actually Planning Around
- Food – feeds your troops and civilian population. It drains constantly, and it's the resource most likely to bleed you dry if you're running a large army without matching food production.
- Lumber – goes into early-to-mid building costs and a chunk of troop training. It's usually the easiest resource to overproduce because most players build sawmills early and never scale them back down.
- Stone – the quiet workhorse resource. It shows up alongside lumber in most early and mid-game building costs, and it's easy to underestimate because it rarely spikes the way ore or gold does, right up until a building tier suddenly demands a lot more of it than the last one.
- Ore – becomes the bottleneck resource past the mid-game. Higher-tier troops, later building levels, and top-tier research all lean heavily on ore, and most players don't have enough ore tiles nearby to keep up.
- Gold – funds high-level research, some late-game troop tiers, and certain building rushes. It's the resource most players actually buy or convert for, rather than farm purely through tiles.
A resource calculator that only tracks one or two of these gives you a partial answer. You need all five modeled together, because a training queue that looks fine on food and lumber can still stall out waiting on stone or ore.
How to Use the Calculator Step by Step
The calculator is split into three sections: what you need, what you have, and how fast you're actually earning it. Fill them in this order.
Step 1: Enter Resources Required. This is the top panel. Pull the food, lumber, stone, ore, and gold numbers straight from the building, research, or troop training screen you're planning for. Evony shows this exact cost before you confirm the action, so copy it over rather than estimating.
Step 2: Enter Current Inventory. This is the second panel, and it's just what you have on hand right now for each of the five resources, straight from your city resource bar. Don't use your warehouse cap here, use your actual current total. If you're sitting on 1,000 food and nothing else, like a fresh city or one that just spent down its stockpile, enter it exactly as shown.
Step 3: Add Resource Packs, if you're planning to use any. This section is optional and sits below your inventory. If you're holding resource packs in your inventory (the kind you get from events, quests, or the shop) and plan to use them toward this target, enter the amount each pack gives per resource and how many packs of each you'd use. Leave these at 0 if you're not factoring packs into the plan, the calculator treats them as pure production and gathering from here.
Step 4: Open Advanced: Gathering Bonus & Rate. This section is collapsed by default. Expand it to enter your gathering bonus percentage (from research, VIP level, or active buffs) and your hourly production rate for each of the five resources. Use your current boosted rate here, not your base rate, since the bonus slider and the per-hour fields work together to reflect what you're actually earning right now.
Step 5: Hit Calculate. The calculator combines your shortfall (required minus current inventory minus any packs) against your hourly rates and gathering bonus to tell you how long it'll take to close the gap on every resource, not just the one you're watching.
Step 6: Use Copy or Share if you need to save the plan. Copy grabs your inputs and result so you can paste them into an alliance chat or notes app. Share generates a link back to this exact calculation, which is useful if you want to recheck it later after a buff changes or you've gathered more.
Common Mistakes That Blow Up Your RSS Planning
- Ignoring troop upkeep. New players often calculate building costs but forget their army's food consumption is running in parallel. You can hit your building target and still starve your troops if you didn't account for both draws at once.
- Farming the wrong resource. If ore is your bottleneck, sending five marches to gather lumber does nothing for your actual timeline. Check which resource is limiting you before you commit march slots.
- Forgetting warehouse protection limits. Evony's warehouse only protects a portion of your resources from raids past a certain point. If you're stockpiling for a big upgrade, understand your protected cap first, or you're just building a target for enemy players.
- Not accounting for event buffs expiring mid-farm. If your production rate calculation includes a temporary buff that expires before you hit your target, your actual timeline runs longer than the calculator initially showed. Recheck your numbers if a buff is set to run out soon.
Passive Production vs. Active Gathering: Which Should You Prioritize
| Approach | Best For | Downside |
|---|---|---|
| Passive production (buildings, VIP level, research) | Long-term, steady RSS growth with zero troop risk | Slow to scale; requires upfront investment in resource buildings |
| Active gathering (sending marches to tiles) | Closing a specific short-term gap fast | Troops are exposed to attack while gathering, especially on contested tiles |
| Alliance resource gifts/help | Quick top-ups during active events | Depends on alliance activity and generosity; not reliable long-term |
| Resource conversion (using gold or items) | Emergency shortfalls right before a deadline | Costs real resources or gems; not sustainable as a regular strategy |
Most experienced players run a mix: passive production covers baseline growth, and gathering marches close the gap right before a specific upgrade or event deadline. Relying only on gathering marches burns time and troop safety you don't need to spend.
Planning Around Events and Deadlines
If you're farming toward a specific in-game event, like a KE (Key of Evolution) sub-event or an SVS (Server vs Server) prep window, your resource math changes. You're no longer planning for "eventually," you're planning for a hard deadline.
In that case, run your numbers backward: figure out how many hours you have left, then calculate the production rate (including gathering) you'd need to hit your target in that window. If the math doesn't close, that's your signal to either scale back the goal, spend gems to speed things up, or lean harder on alliance help.
FAQ
Yes, as long as you input your current boosted production rate rather than your base rate. VIP level, research bonuses, and active buffs all factor into your hourly production, so the calculator's accuracy depends on entering the real, current number from your city screen.
Recheck any time your production rate changes: a buff expiring, a new building finishing, or a VIP level up. A plan built on outdated numbers will drift further off the longer you leave it unchecked.
For most players, ore becomes the mid-game bottleneck first. Food and wood production usually scale naturally from early buildings, while ore requires more deliberate tile control and dedicated gathering marches.
Yes. Troop training costs are just another resource target. Enter the training queue's listed cost the same way you would a building upgrade cost, and the calculator handles it identically.
Warehouse capacity is the total amount of resources your city can hold. Warehouse protection is a separate, usually smaller amount that's shielded from being plundered if you're attacked. Planning a big stockpile without checking your protection limit leaves the excess exposed.
Gathering is more sustainable for regular play. Gem conversion makes sense only for a specific short-term deadline, like a closing event window, where the time saved is worth more than the gem cost.
Your Next Move
Stop guessing your RSS timeline. Plug your current stockpile and production rate into the calculator, check your actual gap, and decide whether passive production, a gathering push, or alliance help gets you there fastest. Planning five minutes ahead saves you hours of wasted march time later.
