OSRS Bond Calculator

How bonds work

An Old School bond bought from Jagex is tradeable. Redeem it for 14 days of membership, or sell it on the Grand Exchange for GP. Sellers pay the normal 2% GE tax (5M cap) — the same rule as other items.

This page loads the live GE high for item 13190 and lets you override it. Use Sell for GP for net coins after tax, Sustain membs for bond burn vs your daily income, and Target GP for store cost and bond count.

Sustaining membership

Rough daily cost is bond price ÷ 14. At 10M per bond that is about 714k GP/day, or ~21.4M per 30 days. Herb runs, dailies, and mid-tier bossing cover that for a lot of accounts; if you are short, raise GP/hr or hours played rather than assuming a flat “3 bonds a month” pack.

FAQ

How much GP do you get from selling a bond?

You sell the tradeable bond on the Grand Exchange. You receive the sell price minus the standard 2% GE tax (capped at 5M per item). There is no separate “redeem for GP” button — membership redemption gives days, not coins.

How many bonds per month for membership?

Each bond is 14 days. Covering 30 days needs about 30 ÷ 14 ≈ 2.14 bonds on average. This calculator uses that rate for the monthly GP burn, not a rounded-up pack of 3.

Where does the live bond price come from?

The OSRS Wiki Prices API latest endpoint for Old school bond (item id 13190), using the current GE high when available. You can override the field if your offer differs.

Is buying bonds worth it vs earning GP?

Compare $/M from a store bond sold on the GE with how long that pile would take at your GP/hr. High-end PvM often beats working IRL for GP; short sessions and startup cash are where bonds usually make sense.
