Accounting Calculators

Estimate statistical safety stock when daily demand variation is independent and lead time is constant. A z-score is supplied directly rather than silently selected.

Separate two useful manufacturing cost views: prime cost combines direct materials and labour, while conversion cost combines labour and overhead.

Value equal recurring payments at a constant discount rate, with an explicit choice between end-of-period and beginning-of-period timing.

Bridge opening to closing retained earnings using income, distributions and separately identified adjustments. A negative balance is a retained-earnings deficit.

Estimate how long current usable stock could cover forecast daily usage without further receipts. This supports short-term stock planning.

Calculate absorption manufacturing cost per unit including allocated fixed and variable factory overhead.

Calculate a level monthly payment and an amortisation schedule showing interest, principal repayment and the remaining balance. A zero-rate loan is supported.

Calculate a simple holding-period return including supplied cash income and costs. This measures the total period, rather than an annualised return.

Compare inventory cost with an estimated net realisable value and calculate a potential item-level write-down.

Plan units to manufacture from expected sales and the desired change in finished-goods inventory. This links the sales plan to factory output.
