Formula
const investment = inputs.initialInvestment; const contribution = inputs.annualContribution; const years = inputs.investmentHorizon; const rate = inputs.expectedReturnRate / 100; const fee = inputs.managementFee / 100; const tax = inputs.taxRate / 100; let futureValue = investment; for (let i = 0; i < years; i++) { futureValue = futureValue * (1 + rate - fee) + contribution; } const totalCost = investment + (contribution * years); const capitalGains = futureValue - totalCost; const taxLiability = capitalGains > 0 ? capitalGains * tax : 0; const futureValueAfterTax = futureValue - taxLiability; return { totalInvestmentCost: totalCost, estimatedFutureValue: futureValue, estimatedFutureValueAfterTax: futureValueAfterTax };Initial Investment

GPT-6 Investment Cost Analyzer projects Total Investment Cost, Estimated Future Value (Before Tax), Estimated Future Value (After Tax) using Initial Investment, Annual Contribution, Investment Horizon (Years), Expected Annual Return Rate (%). Investment returns are never guaranteed — historical averages don't predict future results, and fees, taxes, and inflation reduce real returns. Use this as a planning tool, not a promise of outcome, and consider professional advice for large decisions.
Use this finance calculator to compare scenarios before committing money, time, or a provider conversation.
The estimate combines Initial Investment, Annual Contribution, Investment Horizon (Years) and returns Total Investment Cost, Estimated Future Value (Before Tax), Estimated Future Value (After Tax).
If the result changes your decision, verify the current quote, rate, eligibility rule, or provider term before acting.
