Estimate how much you need to save for retirement
Enter your current age, desired retirement age, current savings, monthly contribution, expected annual return, and desired retirement income. Click Calculate to see your projected savings at retirement and whether you're on track.
Key Output — This is the primary number the calculator returns. It represents the answer to the question you asked, calculated using standard financial formulas.
Breakdown Details — These supporting numbers show you how the result was reached. They help you understand what's driving the outcome and where you might adjust your inputs.
What to Look For — Pay attention to how small changes in inputs affect the outputs. The relationship between your inputs and results is where the real insight lives — that's what helps you make better decisions.
Every calculation uses standard financial math — the same formulas banks, lenders, and investment platforms use. The inputs you provide determine the accuracy of the result.
Priya and her husband want to retire at 67. They currently have $18,000 saved across old 401(k)s and a Roth IRA, and can set aside $500 per month together. They're unsure if that monthly amount is enough, and whether they need to increase it now or can wait until their salaries grow.
"I honestly thought $500 a month would give us a lot more. Seeing that it only covers basic expenses makes me realize we need to push for $700, or find a way to increase our income in the next few years."
Takeaway: Starting early helps, but the monthly number still needs to match your lifestyle goals. Don't assume time alone will make up for a small contribution.
Marcus has $142,000 in a 403(b) and a small pension expected at age 65 worth about $1,100/month. He can only contribute $350 per month due to child support and other expenses. He plans to work until 67 but is worried about losing years of compounding from his divorce settlement a decade ago.
"I've been beating myself up for not saving more after the divorce. But seeing that the pension fills a big gap is a relief. I still need to be careful, but I'm not as far behind as I thought."
They want to retire at 64 (Tom) and 66 (Evelyn). They have $780,000 in IRAs and taxable accounts, plus a rental property that nets $1,400/month. They can contribute $2,000 monthly total until retirement. They're unsure whether retiring at different ages creates a shortfall in the early years before Social Security kicks in.
"We always planned for the same retirement date, but it made more sense for me to keep working a bit longer. I was nervous about the overlap period, but running the numbers showed we'd be fine as long as we don't touch the rental income during that time."
Takeaway: Staggered retirement dates create a cash-flow gap that many couples overlook. Running the calculator for each partner's timeline separately reveals whether that gap is survivable or requires a mid-course correction.
See how different inputs affect the result:
| Scenario | Key Input | Result A | Result B |
|---|---|---|---|
| Priya (32) | Monthly contribution | $500 → $840k at 67 | $750 → $1,130k at 67 |
| Marcus (48) | Include pension? | Without pension: $2,300/mo | With $1,100/mo pension: $3,350/mo |
| Evelyn & Tom (61/63) | Return rate assumption | At 5.5%: $870k at 66 | At 4.5%: $798k at 66 |
| Late starter (45) | Starting age vs. monthly amount | $400/mo at 45 → $337k at 67 | $800/mo at 45 → $674k at 67 |
The most powerful lever changes by age: for younger savers, increasing monthly contributions has decades to compound. For mid-career savers, factoring in all income sources (pensions, rentals) often outweighs small tweaks to return assumptions.
