How retail treasury bonds fit into a savings plan
Retail treasury bonds appeal to savers who want a predictable income from a government issuer. You know the coupon, the payment dates and the maturity, which makes it easy to plan around.
This calculator turns the coupon into peso amounts after tax and compares the net yield with inflation, which is the number that matters for buying power. It does not reinvest interest, so the real result may be a little higher if you do.
Compare it with a Pag-IBIG MP2 plan and a savings goal for money you may need sooner.
How the bond estimate works
- Gross interest per year equals the amount invested times the coupon rate.
- If the interest is taxed, the final tax rate is withheld from it. The auto option treats bonds under five years as taxed and longer bonds as exempt, as a planning shortcut.
- Net interest per quarter is the yearly net interest divided by four.
- Yield after inflation compares the net yield with the inflation rate you enter.
Tips to save more
- Match the maturity to when you need the money.
- Do not put your emergency fund in a bond you cannot sell quickly.
- Read the tax and early sale rules in the offer.
- Spread money across savings, bonds and funds.
