Calculate your investment returns effortlessly and accurately with GPT-6's Investment Return Calculator.
Formula
const initial = inputs.initialInvestment; const contribution = inputs.annualContribution; const rate = inputs.expectedReturnRate / 100; const years = inputs.investmentYears; const frequency = inputs.compoundingFrequency === 'Annually' ? 1 : inputs.compoundingFrequency === 'Semi-Annually' ? 2 : inputs.compoundingFrequency === 'Quarterly' ? 4 : 12; let futureValue = initial; for (let i = 0; i < years; i++) { futureValue = futureValue * (1 + (rate / frequency))**frequency + contribution; }; const totalInterest = futureValue - initial - (contribution * years); return { finalValue: futureValue, totalInterestEarned: totalInterest };Initial Investment ($)

Use the result to compare providers, request quotes, or send the scenario to a specialist when the numbers matter.
GPT-6 Investment Return Calculator projects Projected Final Value, Total Interest Earned using Initial Investment ($), Annual Contribution ($), Expected Annual Return Rate (%), Number of Years. 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 ($), Annual Contribution ($), Expected Annual Return Rate (%) and returns Projected Final Value, Total Interest Earned.
If the result changes your decision, verify the current quote, rate, eligibility rule, or provider term before acting.
