Frequently asked questions
What does compounding frequency mean?⌄
Compounding frequency is how often the interest is calculated and added to your balance. More frequent compounding (daily vs. annually) means you earn slightly more, because each time interest is added, it starts earning its own interest sooner.
Does this account for inflation or taxes?⌄
No — this calculator shows nominal returns only, not real (inflation-adjusted) returns. It also does not account for taxes on investment gains, which vary by country and account type.
Can I use this for retirement planning?⌄
Yes — enter your current savings as the principal, your monthly retirement contribution, an estimated annual return (many use 5–7% for long-term projections), and your years to retirement for a ballpark estimate. It's a projection, not a guarantee.
