Overview

How the Savings Goal Calculator Works

A savings goal is just a number, a date, and a starting balance. This calculator solves the future-value-of-an-annuity equation for the monthly contribution you need to bridge the gap — accounting for the interest your money will earn along the way.

Formula

The Math Behind the Calculator

FV = PV(1 + r)^n + PMT × [((1 + r)^n − 1) / r], where PV is your starting balance, r is the monthly rate, n is the number of months, and PMT is the monthly contribution. Solving for PMT: PMT = (FV − PV(1 + r)^n) × r / ((1 + r)^n − 1).

Example

A Worked Example

Goal: $30,000 down payment in 4 years (48 months). Starting balance: $5,000 in a 4% APY high-yield savings account. Required monthly contribution ≈ $470. Total contributed ≈ $22,560; interest earned ≈ $2,440.

How to use

How to Use the Savings Goal Calculator

  1. 1Enter your goal amount and target date (or number of months).
  2. 2Enter your current savings — even zero is fine.
  3. 3Use a realistic expected return: 4–5% for HYSAs and CDs, 6–8% for diversified stock-heavy portfolios.
  4. 4If the monthly contribution is uncomfortable, either extend the timeline or trim the goal.
Interpretation

What the Results Mean

  • Monthly contribution is what you need to set aside on autopilot.
  • Interest earned shows how much of the gap is closed by compounding rather than by you.
  • If the contribution is zero, your starting balance and rate already get you there — but check if your assumed rate is realistic.

Common Mistakes to Avoid

  • Assuming stock-market returns for a goal you need in 1–2 years — short-horizon money belongs in a savings account, not the market.
  • Forgetting taxes on interest in a taxable account.
  • Skipping a few months 'just this once' and pushing the deadline back without recalculating.

Frequently Asked Questions

What rate should I assume?+

Match it to the account: 4–5% for high-yield savings, 5%+ for CDs, 6–8% long-term for diversified stock portfolios. Conservative beats optimistic when a real deadline is involved.

Are contributions taxed?+

Contributions to taxable accounts aren't taxed, but the interest they earn is. Tax-advantaged accounts (Roth IRA, 401(k)) shelter the growth.

What if I can't afford the monthly?+

Stretch the timeline, lower the goal, or do both. The math always balances — the only question is which lever you'd rather pull.
