RektCalc is free. To keep it free, some links — mainly to crypto exchanges (Bybit, Binance, OKX, KuCoin) and a few tools — are referral or affiliate links.
What it means
If you sign up through one of our links, we may earn a commission or a share of trading fees. It costs you nothing extra, and you often get a sign-up fee discount or bonus.
Our promises
1. A commission never changes a calculation, comparison or recommendation.
2. Affiliate links are marked rel="sponsored" and labelled where they appear.
3. If the better answer is a free or non-affiliate option, we say so.
Not financial advice
Nothing on RektCalc is financial, investment or trading advice. Leverage and crypto are high-risk. See our risk disclaimer and always do your own research.
