Quick guide
How to use this calculator
- Enter the amount, quotation direction, timing, and fees from the real scenario you want to evaluate.
- Use consistent currencies and periods; provider quotes can differ because they include different spreads, deductions, and settlement conventions.
- Read the companion outputs and boundaries before comparing providers, planning a payment, or interpreting a currency result.
Calculation method
Calculation method
Profit = [target principal × (1 + target simple annual yield × days ÷ day-count basis)] ÷ exit rate − funding principal × (1 + funding simple annual rate × days ÷ day-count basis) − fees.
Calculations use exact fixed-decimal arithmetic. No live rate, provider price, country rule, or legal payment obligation is selected automatically.
Worked example
Worked example
Borrowing 10,000 at a 2% simple annual rate, investing at a 5% simple annual yield for 365 days on a 365-day basis, and exiting at the unchanged rate produces a positive carry before fees.
Profit = [target principal × (1 + target simple annual yield × days ÷ day-count basis)] ÷ exit rate − funding principal × (1 + funding simple annual rate × days ÷ day-count basis) − fees.
Supported inputs
Precision and limits
Entered quote and fee scope
This simple-interest scenario allows signed entered rates and remains unhedged. Exchange-rate moves, compounding, leverage, liquidity, rollover, taxes, margin calls, and actual borrowing or investment access can overwhelm the entered interest differential.
Currency and quotation direction
Labels state the required quotation direction. Reversing a currency pair without taking its reciprocal changes the result; all costs must be expressed in the currency named by their labels.
Provider and market boundary
Results are scenarios, not executable quotes. Actual rates, payment acceptance, transfer speed, intermediary deductions, settlement timing, disputes, and provider eligibility may differ.
Regulatory boundary
The calculator does not determine disclosure compliance, lawful surcharges, refund or chargeback rights, tax, sanctions, money-transmission obligations, or consumer protections in any jurisdiction.
Precision and privacy
Plain decimals accept up to 30 digits and 12 decimal places. Calculations remain in this browser and raw entered values are not submitted to 365CALCS.COM.
