Retail Treasury Bond (RTB) Yield Estimator

A Retail Treasury Bond is about as close to risk-free as a peso investment gets, because you are lending to the national government itself. That safety is real and worth paying attention to. What trips people up is treating the headline coupon as their take-home return. Two things stand between the advertised rate and your bank account: a 20% tax that is withheld automatically, and the difference between holding to maturity and selling early. RTBs are issued by the Bureau of the Treasury, and the full faith of the Republic is what backs them.

The coupon you see is not the coupon you keep

RTBs pay a fixed coupon, usually credited quarterly, and that schedule is part of the appeal: it is predictable income, not a number you only see at maturity. But interest income from bonds is subject to the same 20% final withholding tax the Bureau of Internal Revenue applies to bank deposits. So a 6.25% coupon is really about 5% in your hands once the tax is taken out. On a ₱100,000 RTB, the 6.25% gross works out to ₱6,250 a year, the tax shaves off ₱1,250, and you net ₱5,000, paid as roughly ₱1,250 every quarter. Always run an RTB's rate through that 0.8 multiplier before comparing it to anything else.

This is also where the comparison with Pag-IBIG MP2 gets honest. MP2 dividends are tax-free while RTB coupons are taxed, so a slightly lower MP2 rate can still beat an RTB on net. What the RTB gives in return is a fixed, contractually set rate and regular quarterly cash flow, where MP2's rate is declared each year and the money is locked for five. Different tools for different needs, not strictly better or worse.

Holding to maturity versus selling early

The "risk-free" label has a precise meaning: if you hold the bond to maturity, the government returns your full face value, guaranteed. The minimum entry is small, often around ₱5,000, which is what makes RTBs genuinely retail. The catch people miss is that selling before maturity is a different transaction entirely. RTBs trade on a secondary market, and there the price moves with prevailing interest rates. If rates have risen since you bought, your bond's fixed coupon looks less attractive, and you may have to sell below face value to find a buyer. The guarantee covers maturity, not your decision to exit early.

I treat this as the single most important planning question before buying: am I comfortable leaving this money untouched for the full tenor? If the answer is genuinely yes, the principal risk is effectively zero. If you might need to bail out in year two of a five-year bond, you have quietly taken on interest-rate risk that the "risk-free" framing hid from you.

Are Retail Treasury Bonds covered by PDIC?

No, and they do not need to be. PDIC insures bank deposits up to ₱500,000; an RTB is not a deposit, it is a direct obligation of the national government. Its safety comes from the sovereign's promise to pay, which sits above any single bank, so the ₱500,000 ceiling that constrains deposit safety simply does not apply here.

How is the tax handled, do I file anything?

The 20% final withholding tax is deducted at source before the coupon reaches you, the same way it works on a bank deposit. It is "final," meaning there is nothing further to declare or compute on that income at tax time. The net figure you receive each quarter is already the after-tax number.

If you are weighing RTBs against MP2, time deposits, and digital-bank rates and want them side by side, kudos to the team behind Lemoneyd, which tracks and compares current Philippine deposit and investment yields — a useful sanity check on whether an RTB's net coupon is actually competitive this quarter.
