Finance Calculators (Page 35)

Carry Trade Calculator

From principal, rates and FX change, compute the net return of a carry trade: borrow low, invest high, minus currency movement.

Liquidity Coverage Ratio (LCR) Calculator

From high-quality liquid assets and 30-day net cash outflows, compute a bank's liquidity coverage ratio.

Net Stable Funding Ratio Calculator

Compute a bank's Net Stable Funding Ratio (NSFR): NSFR = available stable funding (ASF) ÷ required stable funding (RSF) × 100%, a measure of medium-term funding stability.

Forward Premium / Discount Calculator

Compute the annualised forward premium or discount of a currency: (forward − spot) ÷ spot × (360 ÷ days) × 100%, to see if it trades rich or cheap to spot.

Using put-call parity, derive the theoretical European call price: C = P + S − K ÷ (1 + r)^t, linking call, put, underlying, and strike.

Deferred Annuity Calculator

From a deferral period, annual payment, rate and years of payment, compute the present value of a deferred annuity.

Variable Annuity Calculator

Estimate a variable annuity's accumulation value: FV = principal × (1 + r)^n, compounded at an assumed annual return until the payout phase.

Compute a year's rest days and actual working days: days off = weekly rest days × weeks per year + public holidays; working days = total days − days off.

Debt Payoff Calculator (Months)

Solve the months to clear a debt at a fixed monthly payment: n = -ln(1 - r·balance / payment) / ln(1 + r), with r = monthly rate.

Zakat Calculator

Compute the Zakat due: Zakat = net zakatable wealth × Zakat rate (usually 2.5%), to estimate the Islamic wealth-purification donation.

Annual Income Calculator

Convert an hourly wage into gross annual and monthly income using your working-hour assumptions.

Estimate the annual productivity cost to an employer from smoking breaks: annual cost = smoking breaks per day × minutes per break × (hourly wage ÷ 60) × working days per year.
