Monero confirmation time calculator
Monero blocks come about every two minutes, and received funds are spendable after 10 confirmations, so roughly 20 minutes. Enter the block your transaction was included in to see how many confirmations it has now.
Why 10 confirmations?
Monero locks newly received outputs for 10 blocks. This protects against chain reorganisations: if a reorg removed outputs that a later transaction used in its ring, that transaction would become invalid. Exchanges sometimes ask for more confirmations before crediting a deposit. See sending and receiving Monero.
Want to look up a transaction? Your own wallet shows its height and confirmations. Pasting a transaction ID into a public block explorer tells that explorer you are interested in it, which is a small privacy leak.
