PRO TOOLS
Calculators
Essential tools for fundamental analysis, valuation, and financial planning.
Valuation & Fair Price (Graham, Bazin, Gordon)
Calculate intrinsic fair price and target price for stocks using Benjamin Graham, Décio Bazin, and Gordon models.
Multiples (P/E, P/B, PEG)
Inputs: price, EPS (earnings per share), BVPS (book value per share), and earnings growth (% p.a.). PEG = (P/E) / growth(%).
Average Price and Break-even
Enter your orders with per-order fees. The calculation considers brokerage and fees for each operation for an accurate result.
Financial Independence Simulator
Discover how long it will take to reach your monthly passive income goal, or how much you need to contribute monthly.
Dividend Yield and Yield on Cost
Calculate DY (12m) and YoC with dividend growth. Use 'Purchase price' for YoC; if empty, assumes current price.
DRIP — Dividend Reinvestment
Simulate monthly dividend reinvestment with payout growth. Results assume constant price and fractional shares.
CAGR and Total Return
Inputs: initial/final price, total dividends, and periods (years or months). Outputs: Total return, nominal CAGR, and real CAGR (optional IPCA).
CAPEX vs OPEX (TCO / NPV)
Compare total cost and net present value between purchase (CAPEX + maintenance) and subscription/service (OPEX). Uses annual rate to discount monthly flows.
NPV and IRR
Rate per period, initial investment, and flows per period. NPV = −I0 + Σ(Ft/(1+r)^t). IRR is the rate that makes NPV zero.
Compound Interest (FV/PV)
Project future value with contributions and compound interest. FV = P(1+i)^n + A[((1+i)^n − 1)/i].
Break-even Point
Q = FC / (P − VC). Break-even Revenue = Q × P. We consider Q as an integer (rounded up) to reach equilibrium.
Project ROI and Payback
ROI = (Σflows − investment) / investment. Payback = smallest n such that the sum of flows ≥ investment.
CLT vs PJ vs MEI
Compare monthly net income across three modalities considering taxes and costs to replace benefits. Adjust rates and expenses according to your scenario.
Financing (Price & SAC)
Calculate installments, total interest, and the amortization schedule per period. Interest is interpreted as monthly.
Inflation Adjustment (IPCA)
Adjust values for inflation with a monthly or annual rate and period in months or years.
LTV / CAC
Inputs: Monthly ARPU, gross margin, monthly churn, and CAC. Outputs: LTV and LTV/CAC ratio. Formula LTV = (ARPU × Margin) / Churn.
