Crypto calculators
Six calculators that do the arithmetic properly and tell you what they leave out. None of them predicts anything, and none of them knows your circumstances — a confident-looking number is still only as good as what you typed into it.
- Crypto converter Convert any tracked coin to US dollars, and back, at the current price.
- Profit and loss What a position actually returned once you account for the fees on both sides.
- Return on investment Total and annualised return, so results over different time spans can be compared.
- Dollar-cost averaging back-test What buying a fixed amount on a schedule would actually have produced, using real past prices.
- Position size How large a position can be before a stop-out costs more than you decided to risk.
- Staking and compounding How a stated yield compounds — and how far the token price can fall before the yield stops mattering.
A calculator is not a plan
These answer narrow arithmetic questions. They cannot tell you whether an asset is sound, whether a yield is sustainable, or whether you can afford the loss — and a precise-looking output tends to feel more certain than the guesses that went into it. Treat every result as one input among several.
