How much to save each month to reach a target. Enter goal amount, timeline, and interest rate for a monthly savings plan.

How it’s worked out
  1. What you still need = goal − what current savings grow to = $10,000.00 − $0.00
  2. Monthly saving = still needed × r ÷ (((1 + r)^n − 1) × (1 + r)), with r = 2% ÷ 12 and n = 60 months (deposits at the start of each month)
  3. = $158.35 a month

Savings Goal Calculator

What this calculator does

This calculator determines how much you need to save each month to reach a specific financial goal by a target date, or how long it will take to reach your goal given a fixed monthly savings amount. It accounts for interest earned on your savings along the way.

Whether you are building a $1,000 emergency fund, saving $20,000 for a down payment, or setting aside money for a vacation, wedding, or new car, this tool gives you a clear savings plan with concrete numbers. Seeing the monthly amount broken down makes even large goals feel achievable.

Financial experts consistently recommend having three to six months of living expenses in an emergency fund before tackling other goals. This calculator helps you map out a realistic timeline for that foundation—and any goal that follows.

How to use it

  1. Enter your savings goal amount (e.g. $15,000).
  2. Enter your current savings toward this goal (e.g. $2,000).
  3. Enter the annual interest rate on your savings account (e.g. 4.5% for a high-yield savings account).
  4. Enter either your target date or your planned monthly contribution—the calculator solves for the other.
  5. Review the required monthly savings (or time to goal) and total interest earned.

Formulas used

  • Monthly savings needed to reach a goal: C = (G − P × (1 + r)^n) / [((1 + r)^n − 1) / r] where G = goal amount, P = current savings, r = monthly interest rate (annual / 12), n = total months, C = monthly contribution.

  • Months to reach a goal with fixed contributions: n = ln[(G × r + C) / (P × r + C)] / ln(1 + r) This solves for the number of months when the monthly contribution is known.

  • Total interest earned = Goal amount − Current savings − (Monthly contribution × months)

Examples

Example 1 — Emergency fund: Goal = $10,000, current savings = $500, rate = 4.5%, timeline = 18 months. Required monthly savings ≈ $510. Interest earned ≈ $320.

Example 2 — Down payment: Goal = $40,000, current savings = $8,000, rate = 4%, saving $1,000/month. Time to goal ≈ 30 months (2.5 years). Interest earned ≈ $2,100.

Example 3 — Vacation fund: Goal = $3,000, current savings = $0, rate = 4.5%, timeline = 12 months. Required monthly savings ≈ $244. Interest earned ≈ $72.

Tips and common mistakes

  • Use a high-yield savings account. Traditional savings accounts pay 0.01–0.1% interest, while high-yield accounts offer 4–5%. Over a multi-year goal, this difference can amount to hundreds or thousands of dollars.
  • Automate your contributions. Set up automatic transfers on payday so the savings happen before you have a chance to spend the money.
  • Start with an emergency fund. Before saving for discretionary goals, build a buffer of 3–6 months of essential expenses. This prevents you from dipping into goal-specific savings when unexpected costs arise.
  • Adjust for irregular income. If your income varies, commit to saving a percentage rather than a fixed dollar amount.
  • Don't forget about inflation. A goal five years away may cost more than today's estimate. Add a 2–3% buffer for long-term goals.
  • Celebrate milestones. Breaking a large goal into smaller checkpoints (25%, 50%, 75%) helps maintain motivation without derailing your plan.

Common questions

How do I calculate how much to save each month?

Divide your goal amount by the number of months until your target date. The calculator factors in interest so your required monthly deposit is lower than a simple division.

Should I include interest when planning a savings goal?

Yes. Even modest interest (e.g., 4–5% in a high-yield savings account) reduces the amount you need to contribute out of pocket, especially over longer timeframes.
