Calculator guide
Find the monthly deposit required to meet a savings goal. Use the explicitly labelled inputs below; rates, dimensions, and costs are assumptions, not live quotes.
Formula or method
Grow existing savings for the stated months, then solve the end-of-month deposit annuity for the remaining goal. At 0% interest, monthly deposit = (goal − saved) ÷ months.
How to use this calculator
- Set Savings Goal. The interface starts with 10000; replace it with the value for your scenario.
- Set Already Saved. The interface starts with 2000; replace it with the value for your scenario.
- Set Months to Save (months). The interface starts with 12; replace it with the value for your scenario.
- Set Annual Savings Rate (%). The interface starts with 3; replace it with the value for your scenario.
- Compare the result with the worked example, then vary one assumption at a time so you can see what changes.
Worked example
Enter Savings Goal = 10000; Already Saved = 2000; Months to Save = 12 months; Annual Savings Rate = 3 %. With those assumptions, the calculator gives Required Monthly Savings: $652.55; Amount Still to Fund: $8,000.00. These outputs are calculated from the same implementation as the interactive tool.
Understanding the result
In this example, Required Monthly Savings is $652.55. Amount Still to Fund is $8,000.00. Estimates exclude charges and rules not represented by the inputs. Rates and prices are assumptions; results are not a quote or guaranteed return.
Limitations and assumptions
- Estimates exclude charges and rules not represented by the inputs. Rates and prices are assumptions; results are not a quote or guaranteed return.
- The worked example demonstrates the stated assumptions, not a recommendation about your personal circumstances.
