T. Rowe Price Retirement Income Calculator: Conservative or Pessimistic?

What the calculator does differently

T. Rowe Price's retirement income calculator takes a household's age, savings balance, contribution rate, target retirement age, and produces a projected monthly income figure for retirement — broken down by source (portfolio withdrawals, Social Security, pensions if applicable). The output is in current-dollars, monthly, with a distribution showing the conservative case (worst 10% of trials) and the median case.

Compared to Schwab's, Fidelity's, Vanguard's, and Empower's equivalents, T. Rowe's tool consistently produces the lowest median income figure on identical inputs. We benchmarked using a household scenario to quantify the gap.

The benchmark scenario

Couple, ages 45 and 47, combined income $210,000, $385,000 in retirement savings, contributing 15% of gross annually, target retirement at 65. Current allocation 75/25.

Median monthly retirement income projections (in 2025 dollars):

Calculator	Monthly	vs. Average
Schwab	$8,920	+12%
Fidelity	$8,210	+3%
Vanguard	$8,050	+1%
Empower	$7,940	-0.4%
T. Rowe Price	$6,540	-18%

T. Rowe's projection lands roughly $1,500/month below the next-lowest competitor. On an annual basis, that's an $18,000 gap from the next tool down.

Where the conservatism comes from

Three drivers, in order of impact:

Equity return assumption. T. Rowe's calculator defaults to a 5.7% real equity return for long-horizon projections. Schwab uses 6.4%, Fidelity 5.9%, Vanguard 6.0%. T. Rowe's number is at the low end of the major-firm range but consistent with several recent forward-looking analyses (Vanguard's own 10-year capital markets assumption is in this neighborhood; GMO's is meaningfully lower).

Inflation assumption. T. Rowe defaults to 3.0% annual inflation. The Fed's recent 2.9% trailing reading would suggest this is roughly accurate, but the decade preceding 2022 averaged closer to 2.0%. T. Rowe's 3% is appropriately conservative looking forward; Schwab's 2.5% default is more optimistic.

Sequence-of-returns penalty. T. Rowe applies a more aggressive Monte Carlo approach that gives more weight to bad-early-decade outcomes than some competitors. The mathematical logic is sound — sequence-of-returns risk is real — but it produces lower median outputs.

Together, these assumptions explain about 15 of the 18 percentage-point gap to the average competitor.

What the tool gets right

The healthcare cost modeling is genuinely better than competitors. T. Rowe applies a 5.0% annual escalator on projected healthcare costs in retirement, versus the 3% general-inflation assumption competitors typically use. This produces healthcare cost projections that are roughly 30% higher at age 80 than what a flat-CPI-inflation model would produce.

This matters. Healthcare has historically inflated faster than general CPI by 100-300 bps annually. A retirement plan that assumes flat-CPI for healthcare is structurally understating long-horizon costs.

The sequence-of-returns modeling is also more rigorous. The tool surfaces the conditional outcome assuming a 25% drawdown in years 1-5 of retirement — a scenario most competitors don't display by default.

What the tool can't do

T. Rowe's tool can't import your actual portfolio holdings. It uses a generic asset-allocation-based approach that abstracts away from individual fund selection. For investors holding factor-tilted funds, mid-cap value, emerging markets at non-standard weights, or other non-vanilla allocations, the calculator's projection won't reflect your actual expected return distribution.

The tool also can't model after-tax outcomes for taxable accounts in detail. The output assumes everything is in tax-deferred accounts unless explicitly told otherwise, and even then, the tax-aware drawdown logic is generic.

Should "conservative" win?

Long-horizon retirement projections are inherently uncertain. The right framing is not "which calculator is most accurate" — none of them can be — but "which calculator produces output that's most useful for planning?"

A planning tool that produces an aggressive estimate may flatter the user but fail to flag a real shortfall. A planning tool that produces a conservative estimate may scare the user but signal a problem early enough to address.

We'd rather be flagged early. T. Rowe's tool is doing what a planning tool is supposed to do: surfacing the downside cases prominently so they can be addressed.

The user who runs T. Rowe's tool, sees a conservative median projection, and adjusts their plan accordingly is better off than the user who runs a more optimistic tool, sees a comfortable projection, and discovers the shortfall five years from retirement.

The verdict

T. Rowe's retirement income calculator is the most conservative in the major-firm comparison set, and the conservatism reflects defensible methodology choices rather than pessimism for its own sake. The 5.7% real equity assumption is at the lower end of forward-looking analyst consensus; the 5% healthcare inflation is closer to historical reality than competitors' general-CPI defaults; the sequence-of-returns weighting is more rigorous.

For retirement planning specifically — where being wrong on the conservative side is recoverable and being wrong on the optimistic side is not — T. Rowe's tool is the one we'd pair with another (Schwab or Fidelity) to bracket the realistic range.

Plan against the more conservative number. Bank the upside if the optimistic case turns out right. The asymmetry favors T. Rowe's framing.
