What this calculator helps you answer

The most practical savings question is simple: if I save this much every month, when will I reach my target?

This tool uses just four inputs:

  • Current savings
  • Target amount
  • Monthly savings
  • Estimated annual interest rate (optional)

It then shows:

  • Required months
  • A year/month summary
  • Total contributions
  • Estimated interest earned

How the calculation works

This tool runs a simple monthly simulation.

  1. It starts from your current savings.
  2. It adds your monthly contribution each month.
  3. If you entered an annual rate, it applies a monthly compound rate.
  4. It stops when the balance reaches or exceeds your target.

That makes it useful for quick planning without getting lost in banking details.

Example

  • Current savings: 2,000,000 KRW
  • Target amount: 10,000,000 KRW
  • Monthly savings: 500,000 KRW
  • Annual interest: 3%

→ Required time: about 16 months
→ Period summary: 1 year 4 months
→ Total contributions: 8,000,000 KRW
→ Estimated interest: about 253,661 KRW

FAQ

Can I use this for both recurring savings and deposits?

Yes. It works well for goal-based planning whenever you start from a current amount and add money regularly.

Does a higher interest rate shorten the timeline a lot?

It depends. If your monthly contribution is large, interest may have a smaller effect at first. Over longer timelines, the gap becomes more noticeable.

Are taxes or promotional rates included?

No. This is a quick planning calculator, so taxes, bonus rates, and withdrawal conditions are not included.
