Frequently Asked Questions

Is this calculator accurate?

Our calculations use standard financial formulas and are accurate for the inputs provided. However, real-world conditions (fees, rate changes, taxes) may cause variations.

Should I rely on these results?

Use this calculator for educational planning and rough estimates. For major decisions, consult qualified professionals who can review your complete financial situation.

Methodology

Uses the future value formula: FV = P(1 + r/n)^(nt) + PMT x [((1 + r/n)^(nt) - 1) / (r/n)], accounting for compounding frequency and regular contributions.

Disclaimer: Past performance does not guarantee future results. Market returns are variable and this calculator assumes constant returns for illustration only.

Frequently Asked Questions

Compound interest is interest calculated on the initial principal and also on the accumulated interest from previous periods. This creates exponential growth over time — the "magic" of compounding.

More frequent compounding (monthly vs. annually) yields slightly higher returns because interest is added to the principal more often, so future interest is calculated on a slightly larger base.

"Begin" means contributions are added at the start of each period (earning interest for that full period). "End" means contributions are added at the end (earning interest starting next period).

Inflation reduces the purchasing power of your money over time. The "real balance" adjusts for inflation — showing what your future balance would be worth in today's dollars.
