Most FIRE calculators ignore CPF entirely, or treat it like a magic 401(k). This one models your actual Ordinary, Special/Retirement, and MediSave accounts โ contribution rates, allocation by age, the Special Account closure at 55, and an honest CPF LIFE payout estimate โ alongside the cash and investments you actually control.
Everything recalculates live. Figures are in today's dollars.
CPF is locked until 55 (partial) and CPF LIFE payouts don't start until 65 โ so your real "quit date" depends on your liquid portfolio, not your CPF balance.
Ordinary, Special/Retirement, and MediSave accounts stacked together โ this money isn't accessible on your own schedule.
Cash and non-CPF investments โ this is what has to fund your life between "financial independence" and age 65.
We use the 2026 Ordinary Wage ceiling of $8,000/month and CPF's published age-banded allocation percentages (share of wage going to OA / SA-RA / MA), which shift as you age โ roughly 23/6/8% under 35, down to 15/11.5/10.5% at 51โ55. For ages above 60 we use simplified, lower-confidence estimates since CPF's published tables get sparser there โ check your own CPF Statement for exact figures at that stage.
OA at the 2.5% floor, SA/MA/RA at the 4% floor (extended through end of 2026), plus extra interest on your first $60,000 combined balance (1% under 55; 2% on the first $30,000 and 1% on the next $30,000 from 55). We split extra interest proportionally across accounts as an approximation of CPF's actual OA-first allocation order.
Since January 2025, everyone's Special Account closes at 55. Your SA savings move into a new Retirement Account up to the Full Retirement Sum (FRS); anything above that spills into your OA, where it stays withdrawable. We model that exact mechanic.
For members turning 55 in 2026: Basic Retirement Sum $110,200 (~$950/month from 65), Full Retirement Sum $220,400 (~$1,780/month), Enhanced Retirement Sum $440,800 (~$3,440/month), all Standard Plan estimates. We linearly interpolate/extrapolate your projected payout from these three published reference points โ your real payout depends on the CPF LIFE plan you choose and prevailing rates at 65.
Singapore doesn't have a special flat rate for rental income โ it's simply added to your other chargeable income (like salary) and taxed at ordinary progressive resident rates, which run from 0% on the first $20,000 up to 24% above $1,000,000. We apply IRAS's 15% deemed expense deduction (covering property tax, mortgage interest, repairs, insurance, and agent's fees without needing receipts) to get your taxable rental amount, then compute the marginal tax it adds on top of your salary โ since tax brackets are layered, the same rental income costs more in tax the higher your salary already is. We don't model claiming actual (non-deemed) expenses, which can be higher or lower than the 15% deemed figure depending on your mortgage.
We model portfolio growth at 7% real for equities and 2.5% real for bonds — "real" meaning after inflation, so every figure on this page is genuinely in today's money.
What changed: this calculator previously used 7% and 3% nominal returns while holding your retirement spending flat at the figure you entered, and still described the results as being in today's dollars. That combination was internally inconsistent: if growth is nominal, spending has to rise with inflation too. We have aligned this page with our main calculator's real-return assumptions. The effect on your date is modest — roughly 0.1 to 1.2 years later depending on your settings, with the largest change for bond-heavy allocations, since only the bond figure moved.
What we have not resolved: whether 7% real for equities is itself too optimistic. It sits at the upper end of current long-run expectations. We would rather show you the assumption plainly than defend a single number, so the Expected real investment returns selector above lets you re-run everything at 6% / 2% or 5% / 1.5%. If your date moves a lot between those settings, that gap is your real exposure to market risk.
Annual Wage (bonus) CPF ceiling, employer CPF for wages above $8,000 in ways beyond the ceiling, SRS accounts and their tax relief (contributions are 15% of a $102,000 income base for Citizens/PRs, giving a $15,300/year cap โ but 35% for foreigners, so up to $35,700/year, which makes SRS a far larger lever for EP and S Pass holders than for locals), housing withdrawals from OA, and self-employed MediSave contribution formulas (based on net trade income bands, not modelled here โ self-employed users should use the voluntary top-up slider to approximate their own MediSave contributions). CPF balances are projected deterministically (CPF pays a fixed rate, so there's no market risk to simulate). Your non-CPF liquid portfolio, however, is also shown as a single deterministic growth line here for simplicity โ it does not run the full Monte Carlo range-of-outcomes simulation our main calculator uses, so treat the "years to liquid FI" figure as a rough midpoint estimate, not a probability-weighted one.
