How much should I save every month?
For a specific goal, subtract what you have already saved from the target and divide the remaining amount by the months available. That gives a simple monthly target before investment returns, taxes or changing contributions.
Run the scenario.

- A goal with a deadline is easier to calculate than a vague percentage of income.
- Already-saved money reduces the amount that still needs to be funded.
- A shorter deadline increases the required monthly contribution.
- This simple goal calculator intentionally ignores investment returns so the target is easy to audit.
Turn the goal into a monthly number
If your goal is $12,000, you already have $2,000 and you have 20 months left, the remaining $10,000 divided by 20 gives a $500 monthly target.
You can use the same structure for a trip, emergency fund, purchase or other fixed goal. Change the deadline to see how much flexibility time creates.
Do not confuse a goal calculation with a complete financial plan
A monthly savings target does not decide whether the goal should come before debt repayment, retirement contributions or other priorities. Those are broader planning choices.
NumLuma keeps this tool narrow: it answers how much must be added each month to move from the current amount to the stated goal by the stated deadline.
Quick questions.
Does the calculator assume interest or investment growth?
No. It uses a simple straight-line savings target so the result is transparent.
Can I use it for an emergency fund?
Yes. Enter the emergency-fund amount as the goal, what you already have, and the number of months you want to take.
