Investment Calculators

See how contributions and an employer match could grow into retirement savings with MiniWebtool’s 401(k) Calculator. The projection combines your balance, salary, retirement age, and assumed investment return, allowing you to compare savings choices under those assumptions.

Will your savings last through college? MiniWebtool’s 529 College Savings Calculator projects contributions and investment growth against rising education costs, then simulates withdrawals through the college years. It also estimates the monthly contribution needed for your chosen funding goal.

MiniWebtool’s Black-Scholes Option Pricing Calculator estimates theoretical European call and put values from price, strike, maturity, volatility, interest rate, and dividend yield. Greeks and charts show sensitivities within the model’s assumptions.

Calculate capital employed using multiple methods in MiniWebtool’s Capital Employed Calculator, with a visual breakdown, step-by-step calculations, ROCE analysis, and an interactive balance sheet diagram.

Spread a deposit across staggered maturities in MiniWebtool’s CD Ladder Calculator. Set the investment, rung spacing, and individual rates to see blended APY, liquidity dates, and a modeled rollover path.

Track contributions as well as interest in MiniWebtool’s Compound Savings Calculator. Initial savings, recurring deposits, rate, and compounding assumptions produce a projected balance, with inflation-adjusted values to compare future purchasing power.

Estimate a required shareholder return in MiniWebtool’s Cost of Equity Calculator. Choose the dividend discount model or CAPM, then provide dividend-growth or market-risk inputs to see the modeled cost of equity.

Project share accumulation in MiniWebtool’s Dividend Reinvestment Calculator. Initial investment, dividend yield and growth, price appreciation, contributions, and tax assumptions model how reinvested distributions affect future shares, income, and portfolio value.

MiniWebtool’s Dollar Cost Averaging Calculator models fixed investments made at regular intervals. Contribution amount, frequency, horizon, expected return, and optional initial balance produce a projected portfolio under those assumptions, rather than a historical backtest.

MiniWebtool’s EPF Calculator projects an Indian Employees’ Provident Fund balance from salary, contributions, raises, and interest assumptions. It separates the employer amount diverted to EPS and models monthly accrual with financial-year-end interest credit.

Project price levels beyond an initial move in MiniWebtool’s Fibonacci Extension Calculator. Three A-B-C points define extension targets on the selected scale; these are technical-analysis reference levels rather than predictions of future prices.

Mark Fibonacci-based levels for a move in MiniWebtool’s Fibonacci Retracement Calculator. Start and end prices produce retracement and extension references on a visual price ladder; a calculated level does not guarantee support or resistance.

MiniWebtool’s FIRE Calculator projects a financial-independence timeline from savings, income, expenses, assumed returns, inflation, and withdrawal rate. The target and retirement timing describe a scenario, not a promise that a portfolio will fund spending indefinitely.

Project health savings account growth using MiniWebtool’s HSA Calculator. Age, contributions, employer match, and assumed returns feed a comparison with a taxable account, while annual-limit checks help you review the contribution scenario.

Find the discount rate at which a cash-flow series has zero net present value. MiniWebtool’s IRR Calculator analyzes variable investment cash flows and illustrates NPV sensitivity; unusual cash-flow patterns can complicate IRR interpretation.

MiniWebtool’s Kelly Criterion Calculator estimates a capital fraction from your assumed probability and payoff. Full and fractional Kelly comparisons illustrate the model’s risk implications; inaccurate input assumptions can substantially change the suggested fraction.

Fees can compound against investment growth. MiniWebtool’s Mutual Fund Calculator models contributions and assumed returns after expense ratios and front-end loads, with side-by-side scenarios showing their estimated long-term cost.

Calculate your National Pension System maturity corpus, the tax-free lump sum and the monthly pension you can expect with MiniWebtool’s NPS Calculator. Watch your wealth grow year by year and use the annuity-versus-lump-sum slider to find the split that suits you.

MiniWebtool’s NPV Calculator discounts projected cash flows to compare them with an investment’s initial cost. NPV, IRR, profitability index, and payback calculations provide different views of the same cash-flow assumptions.

Estimate expiration profit probabilities for supported option strategies with MiniWebtool’s Options Probability Calculator. Implied volatility and break-even prices drive the model; the probability estimate depends on its assumptions and does not predict an actual trade’s outcome.

Calculate and visualize the profit/loss potential of Long Call and Long Put option strategies at expiration with MiniWebtool’s Options Profit Calculator, including interactive payoff diagrams and comprehensive risk analysis.

See when an investment recovers its initial cost in MiniWebtool’s Payback Period Calculator. Year-by-year cash flows produce simple and discounted payback estimates, with a timeline distinguishing nominal recovery from recovery after discounting.

Enter salary, years of service and the benefit multiplier in MiniWebtool’s Pension Calculator to estimate the pension, an early-retirement cut and COLA-adjusted income.

Model Indian Public Provident Fund savings with MiniWebtool’s PPF Calculator. It uses a 7.1% rate assumption to build a year-by-year passbook and compares deposit timing and five-year extensions; rates and applicable tax treatment can change.

Explore retirement funding under explicit assumptions with MiniWebtool’s Retirement Calculator. Savings, contributions, spending, inflation, and return estimates drive annual projections and Monte Carlo scenarios, with optional Social Security income; modeled success is not a guarantee.

Estimate a US retirement-account distribution with MiniWebtool’s RMD Calculator. Account balance, age, and applicable life-expectancy factors determine the modeled minimum, with projections and optional tax assumptions for planning.

MiniWebtool’s Roth IRA Calculator projects account growth from ages, balances, contributions, and assumed returns. Compare Roth and Traditional IRA scenarios using current and retirement tax brackets; projections depend on those assumptions.

MiniWebtool’s Savings Calculator projects a balance from an initial deposit, regular contributions, and an assumed interest rate. Choose compounding and duration to view yearly growth and optional inflation-adjusted values.

Work backward from a target balance with MiniWebtool’s Savings Goal Calculator. Current savings, time available, assumed return, and contribution frequency determine the estimated regular savings needed to reach the goal.

Calculate your portfolio's Sharpe ratio with MiniWebtool’s Sharpe Ratio Calculator using return, risk-free rate, and volatility, or enter periodic returns. Review the calculation steps.

MiniWebtool’s Short Selling Profit Calculator calculates short selling profit or loss including stock borrow fees, margin interest costs, and commissions. Visualize your short position breakdown with interactive charts and detailed cost analysis.

Project regular investing with MiniWebtool’s SIP Calculator. Monthly contributions, an assumed return, and investment duration determine modeled growth, with options for annual contribution increases and an initial lump sum.

MiniWebtool’s Social Security Benefits Calculator estimates US retirement benefits from birth year, average earnings, and filing age. Compare claiming from 62 to 70 with assumed COLA, break-even ages, and lifetime totals.

Evaluate downside-adjusted performance with MiniWebtool’s Sortino Ratio Calculator. Use summary inputs, calculate from periodic returns, or compare up to five portfolios against a chosen minimum acceptable return.
