About
CarryFlow is a clean, fast calculator for carry trades, FX margin and interest costs — built for active investors who borrow in one currency and invest in another.
Everything runs on your device. No account login, no broker connection, no data collected.
CARRY & NET SPREAD
• Pick a borrow and an invest currency, type one amount and CarryFlow fills in the other using daily mid-market FX rates.
• See your net interest spread, annual and daily carry, and the effective tiered borrowing rate.
• Choose any base currency to read every figure in one unit.
• Flip the quote direction (1 USD = ? CHF, or the reverse).
BENCHMARK RATES, YOUR WAY
• Reference overnight benchmark rates for 10 major currencies (USD, EUR, GBP, JPY, CHF, HKD, CNH, AUD, CAD, SGD).
• Add your own tiers and spreads to match any broker's margin schedule — CarryFlow is broker-agnostic.
POSITION & LEDGER
• Position sizer: turn capital and a target allocation into a clean share count, and track how much capital is deployed.
• Ledger: log buys, see weighted-average cost per symbol or pair, and close a position in one tap.
CUSTOM PRODUCTS
• Parking borrowed cash in a short-term product such as a T-bill ETF? Add its yield and tax rate, and CarryFlow uses the after-tax yield in your carry math.
RISK (PRO)
• Liquidation calculator: see how far price can fall before equity hits the maintenance line.
MADE FOR EVERYONE
• 9 languages, light / dark / champagne / pink themes, and gain-up or loss-up color presets.
• Private by design: your tiers, spreads, ledger and settings never leave your phone.
CarryFlow Pro is a one-time purchase (not a subscription) that unlocks the Risk tools and future Pro features. Optional tips help support development.
CarryFlow is a calculator for reference and education only. It does not provide investment advice, real-time broker data, or trade execution. Always confirm rates and charges with your own broker.
