Finance Calculators

Choose the right calculator

Start with arithmetic, calculate a percentage, compare your own budgets, or estimate payments for a loan using the values you enter.

Online Calculator

Evaluate an arithmetic expression.

Percentage Calculator

Calculate a percentage, ratio, or change.

Discount Calculator

Find the sale price and savings.

CPM Calculator

Calculate CPM, CPC, CTR, conversion rate, ROAS, ROI, and acquisition costs from your campaign figures.

Annuity Future Value Calculator

Find the present or future value of one principal or a stream of payments, with payments at the beginning or end of each period.

NPV Calculator

Discount up to 120 periodic cash flows to calculate net present value and search for possible internal rates of return.

Dividend Yield Calculator

Calculate annual dividend income, current yield, yield on purchase price, and an illustrative dividend projection.

Rent Prorate Calculator

Prorate monthly rent for a move-in or move-out date using actual calendar days or a selected 30-day convention.

Mortgage Calculator

Estimate fixed-rate mortgage principal and interest from a loan amount, annual nominal rate, and term. Optional loan insurance and upfront fees are entered by you. The calculator does not model the home purchase price, down payment, property taxes, homeowner’s insurance, PMI, or closing costs.

Loan Calculator

Estimate a fixed-rate amortizing loan payment, total interest, and total paid from the amount, annual nominal rate, and term you enter. Optional loan insurance and fees are included only if entered.

Auto Loan Calculator

Estimate an auto-loan payment from vehicle price, down payment, trade-in value, entered financed fees, rate, term, optional loan insurance, and optional final balloon payment. No tax or current lending rate is filled in automatically.

Personal Loan Calculator

Estimate monthly payments, interest, and total payment for a fixed-rate personal loan. Enter your own fees and loan insurance, and optionally enter a second offer for a manual comparison.

ROI Calculator

Calculate simple return on investment from entered initial and final values, additional income, and costs. CAGR is a separate mode that annualizes only the change from initial to final value over the entered years; it excludes additional income and costs. Neither mode retrieves returns or recommends an investment.

Rental Yield Calculator

Compare gross rental yield, net yield before income tax, and cash flow using your property cost, rent, vacancy, annual expenses, property tax, and financing amounts. Every cost is entered by you; the result is a scenario, not a guaranteed future return.

Profit Margin Calculator

Calculate gross profit from unit selling price minus unit cost, then compare profit margin on selling price with markup on cost. The two percentages have different denominators. This simple gross margin omits other overhead and does not estimate net profit or sales tax.

Break Even Calculator

In units mode, divide fixed costs by the contribution per unit. In annual revenue mode, divide fixed costs by the entered contribution margin ratio and compare the result with a chosen number of reference days. Costs and prices are your inputs, not industry assumptions.

Working Capital Calculator

Working Capital = Current Assets − Current Liabilities. Enter both amounts; the result may be positive, zero, or negative. It is an arithmetic measure, not a diagnosis of financial health.

Ebitda Calculator

Calculate EBITDA directly from net income or loss plus net interest expense, income tax expense or benefit, depreciation, and amortization for the same accounting period. Enter net interest income or an income tax benefit as a negative amount. This English mode does not use the separate French operating-surplus formula. The arithmetic does not verify the accounting classification of your entries.

Sales Tax Calculator

Add or remove sales tax using the price and rate you enter. No location-based rate is retrieved.

PTO Accrual Calculator

Estimate PTO hours accrued and remaining using the accrual rule and balance you enter.

Severance Pay Calculator

Estimate gross severance using the weekly pay and weeks or user-entered years-of-service factor.
