What to do next
What this means
2025 Contribution Limit is $4,300.00. This projects how your contributions and assumed return compound over the horizon you entered.
Is this good or bad?
The result is healthy when contributions — not the assumed return — do most of the work.
What's the risk?
Projections assume a steady return. Real markets deliver the average through very uneven years.
What should you do next?
Re-run the projection with a lower return assumption and confirm the plan still works.
Your action plan
- 1
Capture the full employer match
It is the only guaranteed return available to most savers.
- 2
Automate contributions on payday
It removes behaviour risk from the plan.
- 3
Re-run at a lower return
If 5% breaks the plan, the plan is too fragile.
- 4
Check fund expense ratios
A 1% fee compounds into a large lifetime cost.

Common U.S. scenarios

$25k IRA balance at 35 → ~$220k at 65 at a 7% real return with $500/month added.
Seattle high earner
Backdoor Roth is the go-to for filers above the $161k (single) direct Roth income cap in 2025.
Florida retiree
RMDs start at age 73. A partial Roth conversion in early 60s can shrink future RMDs.

What your result means
- Term life is typically 5–10x cheaper than whole life for the same coverage amount.
- Your coverage should replace 10–12x your annual income for dependents.
- Premium quotes vary widely by carrier — always compare at least 3.
How does the formula work?

Common mistakes to avoid
- Under-insuring based on today's income only, not future needs.
- Confusing sum assured with maturity value.
- Skipping riders that materially change the premium.
Pro tips
- Get quotes from at least 3 carriers before renewing.
- Level-term policies are often cheaper than annual renewable term over 10+ years.
- Match the coverage term to the length of the obligation you're protecting.
Why use this calculator
- Estimate premiums without giving up your phone number.
- Compare term lengths and coverage amounts in one view.
- Understand the drivers of your quote before speaking with an agent.
- Unbiased — we don't sell policies or take commissions.
Limitations to keep in mind
- Actual premiums depend on underwriting, medical exam and carrier.
- Does not account for state-specific mandates or riders.
- Estimates only — final quote must come from a licensed carrier.
- Not a solicitation, offer to sell insurance or advice.
Key terms explained
- Term life
- Coverage for a fixed period (e.g. 20 years). Pays out only if you die within the term — the cheapest way to buy pure protection.
- Whole life
- Permanent coverage with a cash-value component. Premiums are 5–10x term for the same death benefit.
- Rider
- An optional add-on to a base policy — waiver of premium, accidental death, critical illness. Riders change the price and coverage.
- Underwriting class
- The risk tier a carrier assigns based on health, lifestyle, and family history. Preferred Plus can cost half of Standard for the same policy.
- Deductible
- The amount you pay out of pocket before the insurer starts covering claims. Higher deductibles usually mean lower premiums.
Before you decide
- Compare quotes from at least 3 A-rated carriers before signing.
- Match the term length to the obligation (mortgage payoff, kids through college).
- Read the exclusions section — that's where claim denials usually start.
- Have an independent advisor review the policy illustration for whole/universal life.
