Flashcard Deck Time Estimator

Enter your deck size, new-cards-per-day pace, and how long each card takes you to answer. This tool shows two numbers most people never separate: when you'll have seen every card once, and what your daily review load looks like once spaced repetition kicks in.

Models first-pass time and steady-state review load separately

Encodr's daily limits exist to cap exactly this review pile before it compounds - a feed that paces new cards so review never becomes unmanageable.

Why the review number matters more than the finish date

Once cards enter review, they come back on a widening schedule - 1, 2, 5, 7, 10, 14, 21, 30, 45, 60, and 90 days out - so a fixed new-cards-per-day pace doesn't mean a fixed total daily card count. Early on, almost every card you see is new. By the time your deck matures, most days are a mix of a smaller new-card batch plus a growing pile of reviews landing from every interval before it. This estimator models both phases so you can catch an unsustainable pace before you're a month in, not after.

How long it actually takes to finish a big flashcard deck

Deck size and new-cards-per-day pace determine two very different numbers - when you'll see every card once, and what your daily review load looks like after.
