How to use this calculator
What this calculator does
Estimate the monthly deposit needed to reach a target savings amount by a chosen date, including a simple interest-rate assumption when relevant.
How to use it
Enter your savings goal, current balance, interest-rate assumption, and timeline. Use the monthly deposit as a planning target, then compare shorter and longer timelines to see what feels realistic.
What the result means
Use the result as a planning estimate. Compare it against your budget, then account for fees, taxes, timing, and lender or account rules before making a decision.

Scenario guidance
When to use this
Use this when turning a savings target into a monthly action plan for an emergency fund, down payment, major purchase, or short-term cash goal.
Example scenario
A household planning a $20,000 down-payment fund can compare a 24-month timeline with a 36-month timeline before deciding how aggressive the savings plan needs to be.
Inputs that usually matter most
- Savings goal, because it defines the target balance.
- Current savings, which reduces the remaining amount needed.
- Time to save and assumed interest rate, which affect the monthly deposit estimate.
Common mistake to avoid
Do not rely on interest alone to close a large savings gap. Rate changes, fees, taxes, and missed deposits can make the target harder to reach.
How to interpret the result
Use the result as a monthly savings target. If the required deposit is too high, adjust the goal, timeline, or current savings plan before assuming the interest rate will make up the difference.
Results are estimates for planning and education. Actual progress can vary with account rates, taxes, fees, deposit timing, emergencies, inflation, and changes in income or expenses.
Formula
The calculator compounds the current balance monthly, then estimates the recurring end-of-month deposit needed to reach the goal. It assumes deposits are consistent and the interest rate stays unchanged.
Example savings plan
To grow $5,000 into a $20,000 goal over 24 months at 3.5% annual interest, the estimate is about $590 per month. Extending the goal to 36 months lowers the monthly target, while shortening it raises the required deposit.
Frequently Asked Questions
What if I already have enough saved?
The required monthly deposit is shown as $0 when the current balance is projected to meet or exceed the goal under the assumptions entered.
Does this account for taxes?
No. Interest taxes, account fees, and changes in savings yield are not included.
