How it works

Plan your financial future by calculating how much you need to save regularly to reach a specific savings target, considering your initial deposit, interest rate, and time horizon.


The Formula
P = FV_needed_from_contrib * r_contrib / ((1 + r_contrib)^n_contrib - 1)

Where:
P = Periodic Payment
FV_needed_from_contrib = Target Goal - Future Value of Initial Deposit
r_contrib = Rate per contribution period (derived from effective annual rate)
n_contrib = Total number of contribution periods

Worked Example
  1. Example: Saving for a Down Payment

    You want to save $20,000 for a down payment in 3 years. You have an initial deposit of $1,000 and expect an annual interest rate of 4%, compounded monthly. You plan to contribute monthly. How much do you need to save each month? Inputs: Target Savings Goal: $20,000 Initial Deposit: $1,000 Annual Interest Rate (%): 4 Time Horizon (Years): 3 Compounding Frequency: Monthly Contribution Frequency: Monthly Result: You would need to save approximately $510.87 each month to reach your $20,000 goal.


Tips, Assumptions & Limitations
  • Start saving early to take advantage of compound interest and reduce your required periodic contributions.
  • Even small, regular contributions can add up significantly over time, especially with consistent compounding.
  • Review your savings goal and contributions periodically to stay on track and adjust for changing financial circumstances or interest rates.
  • Consider setting up automatic transfers to ensure consistent contributions towards your goal.
FAQ

A Savings Goal Calculator helps you determine the regular periodic payments needed to reach a specific financial target by a certain date, taking into account your initial deposit, the interest rate, and how often interest is compounded and you contribute.

Compound interest means you earn interest not only on your initial deposit and contributions but also on the accumulated interest. The more frequently interest is compounded and the longer your money is invested, the faster your savings grow, potentially reducing the amount you need to contribute regularly.

Yes, this calculator works for any currency, as long as you use consistent currency units for your target goal, initial deposit, and periodic contributions. The results will be in the same currency you input.

If you have an initial deposit, the calculator will factor in its growth due to compound interest over your time horizon. This reduces the amount you need to contribute periodically to reach your goal, as part of your target is already covered by your starting sum.
