OSRS DPS Calculator: exact inputs, visible formula
Use this OSRS DPS Calculator to compare two combat setups by max hit, hit chance, attack speed, damage per second and estimated time to kill.
Compare two setups against the same target

Giant Mole DPS example: attack speed beats the larger max hit
This worked example runs the exact same function as the OSRS DPS calculator above. Both setups use 90 Attack, 90 Strength, 20% accuracy prayer, 23% strength prayer and Slash against the Giant Mole preset. Only equipment bonuses, attack speed and entered cost change.
| Setup | Attack bonus | Strength bonus | Attack speed | Hit chance | Max hit | Calculated DPS | Estimated TTK |
|---|---|---|---|---|---|---|---|
| Setup A | +105 | +100 | 4 ticks | 33.41% | 31 | 2.162 | 92.5s |
| Setup B | +122 | +112 | 5 ticks | 36.77% | 33 | 2.026 | 98.7s |
Setup A wins this standard model despite its lower accuracy and max hit. Attacking every 4 ticks offsets the smaller bonuses, while Setup B attacks every 5 ticks. This is why max hit or purchase price alone can point to the wrong upgrade.
DPS = hit chance × average successful hit ÷ (attack speed × 0.6 seconds). The model calculates attack roll, defence roll and required integer floors before the result.
This is not a complete real-kill prediction. Burrows, movement, overkill, special attacks, named equipment and target-specific effects remain outside the standard model.
What this page helps you decide
OSRS DPS Calculator uses the standard attack roll, monster defence roll, hit-chance and average-damage formulas to compare two standard combat setups by max hit, hit chance, attack speed, DPS, time to kill and incremental DPS per million GP. Change combat style, attack type, levels, equipment bonuses, prayers, speed or target defence to see which setup changes practical damage rather than one isolated stat. The visible boundary matters because Special attacks, phase downtime, complete overkill modelling, immunities, set effects and target-specific damage rules remain outside this first standard-roll model. The primary search intent of this landing page is “OSRS DPS calculator”. It answers that one decision; related pages own different comparisons, methods and entities so two URLs do not compete for the same keyword.

How to interpret DPS
OSRS DPS Calculator is designed to compare two standard combat setups by max hit, hit chance, attack speed, DPS, time to kill and incremental DPS per million GP. It exposes the comparison and the most important omitted variables beside the result.
DPS purpose
compare two standard combat setups by max hit, hit chance, attack speed, DPS, time to kill and incremental DPS per million GP
Useful comparison
Change combat style, attack type, levels, equipment bonuses, prayers, speed or target defence to see which setup changes practical damage rather than one isolated stat.
Do not infer
Special attacks, phase downtime, complete overkill modelling, immunities, set effects and target-specific damage rules remain outside this first standard-roll model.
| Output | Included | Not included |
|---|---|---|
| DPS | Attack roll, defence roll, max hit and attack speed | Special attacks and phase downtime |
| Time to kill | Target Hitpoints divided by model DPS | Movement, mechanics and overkill variance |
| Value comparison | Manual setup cost and DPS difference | Live item prices or resale value |
Use the number, then verify the game state
Set the DPS inputs
Use the current account values needed to compare two standard combat setups by max hit, hit chance, attack speed, DPS, time to kill and incremental DPS per million GP.
Compare one change
Change combat style, attack type, levels, equipment bonuses, prayers, speed or target defence to see which setup changes practical damage rather than one isolated stat.
Keep exclusions separate
Special attacks, phase downtime, complete overkill modelling, immunities, set effects and target-specific damage rules remain outside this first standard-roll model.
Turn DPS into a reliable next step
For DPS, the practical question is how the visible inputs produce the DPS result and where that result stops being exact. OSRS DPS Calculator is designed to compare two standard combat setups by max hit, hit chance, attack speed, DPS, time to kill and incremental DPS per million GP. It exposes the comparison and the most important omitted variables beside the result. DPS purpose matters here because compare two standard combat setups by max hit, hit chance, attack speed, DPS, time to kill and incremental DPS per million GP
The first two checks are calculator purpose: DPS and comparison: Visible inputs. For the first check, compare two standard combat setups by max hit, hit chance, attack speed, DPS, time to kill and incremental DPS per million GP For the second, Change combat style, attack type, levels, equipment bonuses, prayers, speed or target defence to see which setup changes practical damage rather than one isolated stat.
The reviewed status for DPS is exact formula + estimates. Do not infer: Special attacks, phase downtime, complete overkill modelling, immunities, set effects and target-specific damage rules remain outside this first standard-roll model. Use OSRS Wiki: Damage per second to verify DPS mechanics or data before relying on the result.
Apply the result instead of reading it in isolation

Do not let one number answer a different question
For DPS, the boundary is documented as “DPS result interpretation”. Read each row against the stated exact formula + estimates status before using the result.
DPS
DPS evidence: Attack roll, defence roll, max hit and attack speed
DPS check: Special attacks and phase downtime.
Time to kill
DPS evidence: Target Hitpoints divided by model DPS
DPS check: Movement, mechanics and overkill variance.
Value comparison
DPS evidence: Manual setup cost and DPS difference
DPS check: Live item prices or resale value.
