Savings Formula Notes

Quick answer: Savings growth usually combines compound interest on the starting balance plus the future value of recurring deposits.

  • Compound growth: Balance grows based on the annual rate and compound frequency.
  • Recurring deposits: Each deposit may earn interest depending on timing and compounding.
  • Total contributions: Starting balance + all deposits made over the plan period.
  • Interest earned: Future value − total contributions.
  • Real value: Future value adjusted for inflation over time.

FAQ

What is the difference between interest rate and APY?

The interest rate is the nominal annual rate. APY includes the effect of compounding over the year.

Why does contribution timing matter?

Deposits made at the beginning of each period have more time to earn interest than deposits made at the end.

What does inflation-adjusted value mean?

It estimates what your future balance may be worth in today's dollars after inflation reduces purchasing power.

Can I use this for an emergency fund goal?

Yes. Enter your current balance, planned deposits, and time horizon to see how quickly you may reach your target.
