FAQ — no fluff
Straight up
How much does a Dota 2 MMR calibration cost?
Recalibration starts from $23 on lower ranks (up to 2,000 MMR). First calibration and long inactivity carry a ×1.5 multiplier — from ~$35. The higher your previous MMR, the higher the price. The calculator above shows the exact amount — no hidden markups.
How much MMR does calibration give?
Average result for recalibration — +1,000 MMR, for first calibration — +3,000 MMR, for long inactivity — +2,000–3,000 MMR (depends on how far the rating dropped). These are the figures we confirm in the offer: if the result is lower, we refund.
How often can I recalibrate?
Recalibration is available roughly once a year as part of Dota 2's seasonal update. First calibration — only on a new account after playing the initial unranked matches. Long inactivity unlocks if you haven't played ranked for long enough.
What's better — calibration or boost?
If calibration is available — take calibration. In 15–27 games you'll gain +1,000…+3,000 MMR at a fixed price, the fastest and cheapest way to jump your rank. If there's no calibration, or you need a rank above the calibration ceiling — go with boost. You can combine them: calibration first, then boost.
Is calibration safe for the account?
In 5 years and 5,000+ orders — 0 bans. Calibration runs through a residential VPN matching your region, in stealth mode, with a natural game pace. Valve has no automatic calibration detectors — what matters is hygiene, which we keep.
How long does calibration take?
Recalibration (15 games) — 24 hours. First calibration and long inactivity (27 games) — 2 days. With the Rush option — 12 hours for any calibration type. Auto-matching start — 5–15 minutes after payment.
Will my friends find out I calibrated?
No. The booster plays in stealth mode — friends see "offline". KDA and game pace are natural, the medal appears in your profile just like a regular player after calibration. From the outside it looks like you played your own series. The "Stealth mode" option is on by default and free.

Dota 2 MMR calibration guide
Short, to the point, for busy players
What MMR calibration is and why people order it
Dota 2 MMR calibration is a series of ranked games that determines your rating. A new account gets calibrated (27 games, up to +3,000 MMR), active players get a recalibration once a year (15 games, ~+1,000 MMR), and after a long break there's a separate calibration type over 27 games with a +2,000–3,000 MMR gain. People order calibration when they don't want to lose rating because of teammates, when they've just registered an account, or when they haven't played in a while and want to hit an honest maximum.
How much Dota 2 calibration costs — real 2026 prices
The price is calculated by the formula: base price by MMR range × calibration type coefficient × modifiers. At low ranks (up to 2,000 MMR) recalibration starts from $23. In the 2,000–4,000 MMR range — $27–32. At Ancient and Divine — from $38 to $57. First calibration and long inactivity use the same base prices but with a ×1.5 coefficient.
Calibration types — what to choose
- Recalibration (15 games, ×1.0): seasonal calibration for active players. Average gain +1,000 MMR.
- Long inactivity (27 games, ×1.5): unlocks if you haven't played ranked in a while. Gain +2,000–3,000 MMR.
- First calibration (27 games, ×1.5): for a new account only. Average result — +3,000 MMR.
Price modifiers — what to watch for
- Party mode (we play alongside you): +80% to the base price. Play next to the top of the ladder and learn at the same time.
- Rush: +30% to the price, −50% to the timeline. 27 games fit into a single day.
- Smurf pool (under 1,000 matches): +30%. Harder to keep pace without raising suspicion.
- Role or hero selection: +30%. If you want carry only or Invoker only — we set the pool.
- Invisible mode: free. The booster plays offline, friends see you as "offline".
How much MMR calibration gives
The calibration result depends on the type and starting point. First calibration on a new account gives the maximum boost — from Guardian to Legend in one run. Recalibration on an active account is +1,000 MMR on average, which usually raises your rank by 1–2 tiers. Long inactivity — +2,000–3,000 MMR depending on how far your rating dropped and how long you didn't play. The calculator shows the exact MMR number the moment you pick a type.
Is calibration safe for the account
The short answer — yes, if it's done right. Valve officially prohibits account sharing but has no automated systems for detecting calibration. We follow every precaution: a residential VPN matched to your region, invisible mode, a natural game pace. Bans are ruled out when you order from us — 0 bans across 5 years and 5,000+ orders.
Calibration vs boost — what to choose
Calibration is a fast, cheap way to raise MMR sharply. Over 15–27 games you'll get +1,000 to +3,000 MMR at a fixed price. It fits when calibration is available (once a year or on a new account) and you need to land a solid rank right away.
Boost is steady growth across any range on demand. It fits when there's no calibration, or you need to push MMR above the calibration ceiling. The price is calculated per 100 MMR. You can combine them: calibration first, then a boost to your target rank — that works out cheaper than one big boost.
How we work — behind the scenes
1. You calculate the price in the calculator → 2. Payment → 3. Automatic booster matching by calibration type, region and hero pool → 4. The booster logs in and turns on invisible mode → 5. Plays 15/15 (or 27 games) at a natural pace → 6. You follow every match in monitoring → 7. On completion — the order is closed, the medal updated.
How long calibration takes
Recalibration (15 games) — 24 hours by default. First calibration and long inactivity (27 games) — 2 days. With the rush option — 12 hours for any type. Auto-matching starts 5–15 minutes after payment.
What's included in the price
Included: the calibration itself (15/15 or 27 games per the plan), invisible mode, 24/7 monitoring, chat with the booster, manager support, booster replacement if the pace slips, up to 100% money-back guarantee.
